Top Ten Half Marathons in Ireland for 2026

Whether you're a keen runner looking to set a new PB, or you have your eyes on a new medal and a post-race pint, here are some of the best half marathons to pencil into your running in Ireland calendar for 2026.

1. The Irish Life Half Marathon: Dublin's Royal Run

Since the race takes place entirely within the park walls, you get a mix of city race energy and trail scenery.

If you're looking to smash a new PB half marathon time, the Irish Life Dublin Half Marathon is where to do it.

Part of the wider Dublin Marathon Race Series, this 13.1-mile course is designed for speed and is a perfect warm-up to the full Dublin Marathon in October.

Held entirely within the limestone walls of Phoenix Park, a former royal deer park, it's where city energy meets wild scenery. It's also a rare opportunity to see one of Europe's best-loved capitals partially traffic-free and in full cheerleader mode.

📅 The Essentials

  • When is the Irish Life Dublin Half Marathon?: Sunday, September 20, 2026.
  • Start time: 9:00 AM, with wave starts strictly enforced.
  • Start/finish line: Chesterfield Avenue or near Furze Road.
  • Entry fee: Usually €48.15 (€45 plus €3.15 fee). This race is notorious for selling out by April or May.

👟 The Route: City Park Vibes

Don't let the park setting fool you — this course is as challenging as it is beautiful. This course is famously rolling, so you'll rarely be on perfectly flat ground.

You'll spend a significant portion of the race on Chesterfield Avenue, a tree-lined boulevard that feels endless on the return leg. It never lets you get too comfortable, though, as the route ducks into more scenic, twisty sections like the Upper Glen Road.

Most runners find the 10-mile mark a real highlight. This is usually where they spot some of the park's 600+ fallow deer grazing by the roadside. But just as you start getting distracted by the wildlife, the steady drag up towards Castleknock Gate kicks in ahead of the final sprint.

🏅 Perks and Logistics

  • Race pack: Note that there's no race-day collection for this run. Packs are either posted to Irish addresses or you can collect them at a city centre hub on the week of the race.
  • Parking: Parking in the park is a nightmare on race day. Take a Luas Red Line tram to Heuston Station or Parkgate Street and walk in. 
  • The goodies: You get a high-quality technical tee and a chunky medal that usually locks into the other medals from the Dublin Race Series, to form one giant commemorative piece.
  • The finish: The atmosphere at the finish funnel is electric, with local athletics clubs out in force to support runners. 
💡 Insider Tip: Split for the Win

Aiming for a negative split, i.e., finishing the second half faster than the first, is the smartest strategy for conquering the Irish Life Dublin Half Marathon. By keeping your heart rate steady in the early park miles, you'll have the fresh legs you need to fly down the final Furze Road stretch. 

2. Cork City Half Marathon

Cork's colourful cityscapes and world-class food will spur you to the finish line of its popular half marathon

For a premier half marathon Ireland experience, Cork is unbeatable. The Cork City Half is a masterclass in urban running, taking you through the heart of Ireland's 'Rebel City,' with a finish line that feels like a rock concert.

Corkonians call their city the real capital, and during the June Bank Holiday weekend, the atmosphere backs up this claim. 

📅 The Essentials

  • Date: Sunday, 31 May 2026.
  • Start time: 10:15 AM, starting after the full marathoners.
  • Location: Starts on Monahan Road and finishes on St. Patrick's Street.
  • Entry fee: €70.00, which often includes a high-spec finisher's jacket or tee.

👟 The Route: Riverside Miles and 'Pana' Glory

The course is famously flat and fast, but it's the scenery that keeps your mind off the miles. Starting on Monahan Road, you'll head out toward the lush, leafy banks of the River Lee.

A major highlight is the stretch along Cork Marina — a long, shaded riverside road where you can really lock into your target pace.

The finale is legendary. You'll turn onto St. Patrick's Street, known locally as 'Pana', where the crowds are packed ten-deep. The wall of sound here is enough to carry even the most exhausted runner across the finish line.

🏅 Perks and Logistics

  • The vibe: Unlike many city races, Cork residents treat this like a giant street party. Expect unofficial water stations from residents in the suburban stretches.
  • Post-race: You finish in the heart of Ireland's food capital. The English Market is just a short walk away for a world-class post-race brunch.
💡 Insider Tip: The Energy Conserve

The real secret to Cork is 'pacing the Marina.' It's tempting to fly through this shaded, flat section because it feels so easy, but save that 5% extra effort for the final two kilometres through the city streets. The adrenaline from the crowd on 'Pana' is great, but you need the legs to match it.

3. Half on the Head: Kerryhead Half Marathon

As you climb past Glenlea and Tiershanaghan, look back for views of the Kerry coastline towards Ballybunion

Don't fancy the crowded start lines of a city race? The Half on the Head takes you into the untamed beauty of North Kerry for a loop around the Kerryhead peninsula.

Starting in the seaside village of Ballyheigue, this is a road race in the way only the West of Ireland can do it. You're in for a real delight, with quiet winding country lanes, salty air, spectacular coastal exposure and possibly the most scenic 13.1 miles in the country.

If you like your running with a side of Atlantic spray and dramatic cliffs, The Half on the Head Kerryhead Half Marathon is your 2026 must-run. 

📅 The Essentials

  • Date: Saturday, 13 June 2026
  • Start time: 11:00 AM
  • Location: Ballyheigue Village, Co. Kerry. Starts on Ballyheigue Beach and Finishes at Ballyheigue Castle Gates.
  • Entry fee: €35 for the first 100 participants, €45 standard.

👟 The Route: Sky, Sea, and Stone

This isn't a PB course, it's an experience course. You start on the sands of Ballyheigue Beach, tide permitting, and immediately begin a steady climb onto the Kerryhead loop.

You'll be running on narrow, paved roads with the Atlantic Ocean crashing below you and ancient stone walls on the other.

The route is a single loop, meaning the views are constantly changing. On a clear day, you can see across the Shannon Estuary to the cliffs of County Clare and the fabled Cliffs of Dooneen. The final three miles are a glorious, fast descent back into the village, finishing right at the historic gates of Ballyheigue Castle.

🏅Perks and Logistics

  • The vibe: This is 100% community-run. The post-race hospitality in the village is famous — expect a festival atmosphere where the whole town turns out to cheer.
  • The medal: You'll bag a high-quality medal and a technical tee, which usually features a cool, locally-inspired design.
  • Parking: Plenty of parking available in the village and near the beach car park, but arrive early as the village is small.
💡 Insider Tip: Conquering the 'Nine-Mile Hill'

Locals joke that there's only "one hill" on this course... it just happens to be nine miles long. The first half of the race is a relentless, gradual climb as you wind toward the point of the Head. The Secret: Don’t fight the incline. Keep your head up and soak in the views of Mount Brandon; if you pace yourself through the first 14km, the final seven-kilometre descent is a "free ride" to the finish line.

4. Galway Bay Half Marathon

The Salthill Promenade: Flat tarmac, sea air, and pure PB potential

Picture the scene: you're running along the Atlantic edge with the sea breeze in your hair and the distant silhouette of the Burren across the water. If you want to experience the City of Tribes at its most energetic, Run Galway Bay is the ultimate autumn race.

This event is famous for its pancake-flat course and incredible Atlantic views, making it one of the most popular half marathons for runners chasing a late-season PB.

📅 The Essentials

  • Date: Saturday, 3 October 2026.
  • Start time: 10:30 AM
  • Location: Nimmo's Pier, starting and finishing at The Claddagh.
  • Entry fee: €55, includes a famously cool Galway Bay finisher's tee.

👟The Route: The Salthill Swing

This course is a runner's dream if you're looking for a flat route. Starting at the iconic Nimmo's Pier, you head out along the Salthill Promenade. You'll pass the famous Blackrock Diving Tower before looping back. Because it's a multi-lap course, with two loops for the half, the crowd support is constant. Runners are never more than a few minutes away from a cheer.

The terrain is 100% flat tarmac, but while the course lacks hills, the challenge comes from the elements. On a calm day, it's one of the fastest courses in Ireland. On a wild day, the Atlantic will give you a 'Galway facial,' i.e., a face full of sea spray, for the final few miles.

🏅Perks and Logistics

  • The vibe: Relaxed, welcoming, and very Galway. It's a late-season race, so the atmosphere is usually a mix of serious PB-hunters and people enjoying a weekend away in the West.
  • Post-race: Because it's a Saturday morning race, the celebrations start early. By mid-afternoon, the Latin Quarter and the West End are filled with runners wearing their medals and finishers' shirts, creating a city-wide race afterparty that lasts well into the night. The mandatory post-race move is a pint and some live music in a pub like The Crane or Tigh Neachtain.
💡 Insider Tip: The 'Prom Wall'

The Salthill Promenade is beautiful, but the wind direction will be your biggest competitor. If there's a headwind on the way out, don't try to maintain your goal pace, as you'll burn out. Tuck in behind a group of runners (drafting is your friend) and save your energy. The wind almost always flips to a tailwind for the return leg, allowing you to sail home for a fast finish.

5. Regeneron Great Limerick Run Half

The beige stone King John's Castle with a bridge over the River Shannon in Limerick, Ireland.

With views like King John's Castle overlooking the River Shannon, you'll have to resist stopping mid-half-marathon to take photos

Famous for its red-carpet finish and incredible urban energy, Limerick is a bucket-list half marathon for anyone who loves big-city buzz.

It turns Limerick into one giant street party, and the atmosphere is arguably the best in the country outside of Dublin.

📅 The Essentials

  • Date: Sunday, 3 May 2026.
  • Start time: 11:00 AM
  • Location: Pery Square for the start, finishing at O'Connell Street.
  • Entry fee: €67, which includes a technical tee and a chunky finisher's medal.

👟 The Route: A City Tour on Foot

Limerick Half Marathon's course is famously fast and relatively flat, although it has a few character-building drags in the suburbs.

You'll kick off in the scenic Georgian quarter before heading out towards the suburbs of Raheen and Dooradoyle. This is where the local support shines — expect high-fives at every corner.

The highlight for many is crossing the Shannon via Sarsfield Bridge, giving you a sweeping view of King John's Castle as you head toward the home stretch. You'll loop through the North Circular Road before a grandstand finish on a packed O'Connell Street.

🏅 Perks and Logistics

  • Race pack: There is strictly no race-day collection. Pack pickup is at the UL Sport Arena on Friday and Saturday.
  • The goodies: You'll bag a technical tee and a chunky finisher's medal. 
  • Post-race partying: The post-race scene is what makes this weekend truly special. Limerick is Ireland's sporting capital, and the local support here is famously passionate. And because the race coincides with the city's bustling Riverfest, Limerick's streets go into full fun mode, with live music, fireworks, and food stalls around every corner.
💡 Insider Tip: The Merger Mental Game 

Because the Half Marathon starts two hours after the full, you'll merge with the marathon runners for the final few miles. Don't let the slower pace of the marathoners trick you into slowing down. Keep your blinkers on and use your fresher legs to power through the congestion. 

6. Waterford Viking Half Marathon

The dramatic stone seven-arch limestone Durrow Viaduct, a historic railway landmark on Ireland's Waterford Greenway.

The Waterford Viking Half takes runners past landmarks such as the Durrow Viaduct and the Ballyvoile Tunnel

If you want to run through 1,100 years of history in Ireland's oldest city, the Waterford Viking Half is unmissable.

This midsummer race blends ancient Viking heritage with some of the most incredible coastal and countryside scenery in South-East Ireland. It's a real voyage that takes you from the medieval Viking Triangle, out through world-class gardens, and back for a hero's welcome in the city centre.

📅 The Essentials

  • Date: Sunday, 21 June 2026.
  • Start time: 9:00 AM
  • Location: The Mall for the start, finishing at O'Connell Street.
  • Entry fee: The early bird rate of €57.46 (€52.80 plus €4.66 fee) currently applies.

👟 The Route: City Walls to Country Gardens

The course is famously scenic and relatively fast, starting right between the iconic Waterford Crystal and the Bishop's Palace. The highlight of the 13.1 miles is the stretch through the world-famous Mount Congreve Gardens. Running through its vibrant, world-renowned blooms is easily the most Instagrammable mile in Irish racing.

Runners are also treated to sweeping views of the River Suir as the route joins the Waterford Greenway. The final leg brings you back into the city for a grandstand finish on O'Connell Street, where the local crowd support is at its peak.

🏅 Perks and Logistics

  • The medal: You'll bag the iconic Viking Medal, which is consistently voted one of the best-designed medals in Ireland.
  • The vibe: It's a full-on festival. Expect live bands, DJs, and entertainment zones dotted along the route to keep your spirits high.
  • Charity bonus: This race has a big heart. By registering, you're supporting the RNLI, the crews that keep Ireland's coastlines safe.
💡 Insider Tip: The Greenway Glide

While the half-marathon course is mostly flat, the transition onto the Waterford Greenway can be deceptively breezy. Focus on maintaining a steady effort rather than a specific pace during the river stretches. The wind coming off the Suir can fluctuate, so once you hit the sheltered paths of Mount Congreve, you can use your stored energy to enjoy the most beautiful mile of the race.

7. Wicklow Half Marathon

The 12th century ruins of Black Castle on the coast of Ireland near Wicklow on a sunny day.

Runners pass the 12th-century Norman ruins of Black Castle overlooking the Irish Sea early in the race 

Want hills? You've got them. This is the race for runners who love a challenge and don't mind a bit of vertical gain in exchange for world-class views.

Considered to be one of the toughest runs in the country, the Wicklow Half is the perfect way to shake off the winter blues in the Garden of Ireland.

📅 The Essentials

  • Date: Sunday, 22 March 2026.
  • Start time: 10:30 AM
  • Location: Wicklow Town, starting along the Quays.
  • Entry fee: €49.50, includes a unique medal and access to the historic finish line.

👟 The Route: Coastal Cliffs and Historic Gaols

The route is a scenic, single-loop masterpiece that kicks off along the picturesque quays of Wicklow Town.

You'll head out along the coastline, where the air is salty, and the views of the Irish Sea are wide open. Be prepared for a famously hilly course. Its winding country roads will test your resolve, not to mention your glutes, before rewarding you with a spectacular finish.

The grand finale is one of the most unique in Ireland. You'll finish in the courtyard of Wicklow's Historic Gaol, running through the gates of this 18th-century prison to grab your medal. It's a spectacular, atmospheric end to a gruelling 13.1 miles.

🏅 Perks and Logistics

  • The goods: You'll bag a high-quality technical tee and a commemorative medal, which usually features a historic Gaol-themed design.
  • Accessibility: Located only 40 minutes from Dublin, it's one of the easiest scenic races to get to if you're staying in the capital.
  • The vibe: Wicklow Town brings a massive community energy to race day, with locals lining the quays to cheer you home. The atmosphere inside the prison walls at the finish is electric, as it fills with the clatter of medals and post-race high-fives. Because it's an early-season race, the local pubs and cafes are always packed with runners soaking up the spring sunshine and the town's harbour-side charm.
💡 Insider Tip: The Prison Break Push

The final kilometre into the Gaol is a slight incline, and after 20km of hills, it can feel like a mountain. Listen for the finish line music as you pass the town bridge. Once you hear it, pick a target runner ahead of you and chase them through the prison gates.

8. Dingle Half Marathon

A view from Ireland's Slea Head Cliffs looking over Coumeenoole Beach, with green cliffs and a bright blue sea.

Dingle Half Marathon offers the ultimate backdrop, as participants pass Coumeenoole Beach from the Slea Head road

Dingle is a jewel when it comes to Irish half marathons and is arguably the most beautiful race in Ireland.

Held on the Dingle Peninsula, it takes you along the rugged Wild Atlantic Way, where the road is yours, and the views are absolutely world-class.

Run through the colourful streets of Dingle Town out onto Slea Head Drive, enjoying panoramic views of the Blasket Islands and a rugged Atlantic coastline that feels like it's on the edge of the world.

📅 The Essentials

  • Date: Saturday, 5 September 2026.
  • Start time: 9:00 AM
  • Location: Dingle Marina for the start, finishing at Dunquin near Krugers Pub.
  • Entry fee: €74, this legendary race usually sells out a year in advance.

👟 The Route: The Slea Head Loop

The course is famously scenic and entirely traffic-free on race day. You'll start at the Marina and head west along the spectacular Slea Head Drive.

While the hills are challenging, the constant views of the Atlantic act as the perfect distraction. Runners pass beehive huts and jagged cliffs before a spectacular finish at the most westerly point of the peninsula.

🏅 Perks and Logistics

  • The goods: Participants get a high-quality medal and a technical finisher's tee.
  • Transport: Complimentary buses are provided to take you back to Dingle Town to continue the celebrations.
  • The vibe: Dingle has a festival energy that's hard to match. Because the town is a tourist hub, the pubs and streets are packed with supporters and musicians from early morning. The post-race scene is legendary, with finishers filling the local harbourside bars to swap stories over fresh seafood and pints, turning the whole weekend into one big Kerry celebration.
💡 Insider Tip: The Ventry Stretch

This run features a long, steady drag at mile four near Ventry. It's easy to get distracted by the blue flag beach views, but this is where the real work begins. Hold a steady, conservative pace through Ventry so you have the energy to tackle the famous Slea Head cliffs between miles eight and 11.

9. Connemarathon 

The valleys of Ireland's beautiful and quiet Maumturk Mountains, with a waterway passing through long grass fields.

Runners are treated to the silent, rugged valleys of the Maumturk Mountains during the Connemarathon Half

The Connemarathon Half is a journey through the wild heart of County Galway. Starting in the village of Leenane and finishing at Maam Cross, the course features a landscape dotted with deep lakes, roaming sheep, and the towering Twelve Bens mountains.

If you're looking for a raw, "man vs. nature" experience, the Connemarathon is as close as it gets. The remote, lunar-like landscapes and 'four seasons in a day' weather make it a true badge of honour for any Irish runner.

📅 The Essentials

  • Date: Sunday, 19 April 2026.
  • Start time: 11:00 AM
  • Location: Leenane for the start, finishing at Maam Cross.
  • Entry fee: €70, which includes bus transfers from Galway, Oughterard, and Clifden.

👟 The Route: The Quiet Man Country

This is a point-to-point race through some of the most unspoiled terrain in Europe. You will start in the fjord-side village of Leenane and wind your way through the boglands and valleys of Connemara. The road is a mix of long, sweeping straights and two notorious hills that have broken many PBs over the years.

🏅 Perks and Logistics

  • The medal: You will receive a chunky, commemorative medal and a technical tee at the finish line.
  • The vibe: There is a real sense of camaraderie here. Because most runners arrive by bus together, the start line at the Killary Harbour is buzzing with shared nerves and excitement.
  • Post-race: Once you cross the line at Maam Cross, there is a dedicated race village where you can refuel before the buses head back to the main city hubs. For post-race celebrations, the primary hub is Peacockes Hotel. Here, runners gather to warm up and share a meal. It's a quiet, scenic kind of victory that feels deeply connected to the wild West of Ireland.
💡 Insider Tip: The Hell of the West

The final two miles of this race are known as 'The Hell of the West'. It's a relentless, steep climb that kicks in just when you think you are finished. When you see the Maam Cross tower in the distance, don't sprint. Keep your breathing rhythmic and focus on the person's heels in front of you until you crest the final hill. Then, the last 200 meters are a flat dash to the clock.

10. Bord na Mona Tullamore Half Marathon

An Irish farmhouse sitting in the middle of a green field, surrounded by colourful flowers and a blue sky.

Tullamore Half Marathon has one of the flattest routes in Ireland — ideal for smashing your PB before the autumn marathon season

Serving as a major highlight of the late-summer racing calendar, Tullamore Half Marathon is a distinguished event that attracts the best club runners in the country.

Tullamore is famous for being one of the best flat half marathons Ireland has to offer. It's also noted for its exceptional organisation, its scenic loop through the Offaly countryside, and a stadium finish that makes every runner feel like an elite athlete.

📅 The Essentials

  • Date: Saturday, 29 August 2026.
  • Start time: 10:00 AM
  • Location: Charleville Road for the start, finishing with a lap of the Tullamore Harriers Stadium track.
  • Entry fee: €50, including a technical tee and a finishers' medal.

👟 The Route: Country Lanes and Stadium Glory

The course is a scenic, single-loop route that winds through the quiet rural roads of Mucklagh, Killurin, and Cloonagh. It's mostly flat with some gently undulating sections, making it a prime choice for those looking to set a personal best or as a key warm-up for the Dublin Marathon.

Runners are met with an unforgettable experience in the race's final 400 metres. Entering the Tullamore Harriers Stadium, they get to complete a full lap of the tartan track to the sound of the announcer and roar of the crowds. It's one of the most professional-feeling finish lines on the Irish running calendar.

🏅 Perks and Logistics

  • The Goods: Finishers receive a bespoke medal and a high-quality technical tee. Because these are posted to you before the race, you can arrive on the day ready to run without queuing for registration.
  • The vibe: This race has a prestigious, big-event feel, as it often hosts the Leinster and Offaly Half Marathon Championships.
  • Post-race atmosphere: The Tullamore Harriers club grounds become a massive hub of activity post-race, with a friendly, community-focused atmosphere where runners gather to compare times over tea and sandwiches. It's the kind of race where everyone knows your name (or at least cheers for your number), making the post-race celebration feel like a massive neighbourhood homecoming.
💡 Insider Tip: The Stadium Sprint

The transition from the road onto the stadium track can be a shock to the system if you have spent all your energy on the rural miles. The Secret: Treat the first 12.5 miles as the race and the final 400 metres as your victory lap. The springy surface of the track will naturally make you want to sprint, so keep a little bit of power in reserve to make that final dash in front of the grandstand look effortless.

Honourable Mention: Clonakilty Waterfront Half Marathon

Yellow-speckled rocky causeways along the Atlantic Way, near Clonakilty on the coast of Ireland with blue skies and seas in the background.

Crossing the local causeways, the Clonakilty Half Marathon route is famous for its blue-flag beaches and panoramic Atlantic views

The Clonakilty Half Marathon is the ultimate season finale. Held in the picturesque coastal town of West Cork, it's famous for its rolling hills, sea views, and a post-race party that usually lasts well into the night.

📅 The Essentials

  • Date: Typically takes place in late November or early December, 2026 dates are not yet confirmed.
  • Start time: 9:00 AM
  • Location: Quality Hotel Clonakilty for the start and finish.
  • Entry fee: €60, which includes a technical tee and a finishers' medal.

👟 The Route: The Atlantic Edge

The course is a beautiful, undulating loop that takes you out of the town and along the rugged West Cork coastline.

You'll run past the Inchydoney blue flag beach and follow the waterfront for several miles. While there are a few character-building climbs, the sight of the Atlantic crashing against the shore provides a fantastic boost.

The final few miles bring you back into Clonakilty through a tunnel of cheering locals.

🏅 Perks and Logistics

  • The goods: Runners receive a high-quality medal and a technical tee. Clonakilty is famous for its unique medals, which often feature a rotating element or a distinct West Cork design.
  • Location: Just over an hour from Cork City, Clonakilty is one of the most popular weekend-break destinations in Ireland, so it is best to book your accommodation well in advance.
  • The vibe: This is more than just a race — it's a festival. Local pubs and cafes are packed with runners refuelling on the town's famous black pudding and locally sourced seafood long after the race has finished.
💡 Insider Tip: The Inchydoney Wind

The stretch along Inchydoney is spectacular, but because it is so open to the sea, you'll likely face a strong coastal breeze. Don't fight the wind on the outward stretch — keep a steady pace and tuck in behind other runners to save energy. Once you turn towards the town, the wind is usually at your back, giving you a massive boost for the final five-kilometre sprint to the finish.

FAQs: Top Ten Half Marathons in Ireland for 2026: Dates and Expert Tips

1.) What is the best half marathon in Ireland?

The Irish Life Dublin Half Marathon is widely considered the best overall race due to its world-class organisation and the prestige of running in Phoenix Park. Dingle Half Marathon in County Kerry is noted for being the most beautiful, featuring coastal views along the Dingle Peninsula. Connemara Half Marathon is believed to be the most challenging, with its demanding but scenic route, and Antrim Coast Half Marathon is considered one of the fastest and flattest and perfect for personal bests (it is, however, full for 2026).

2.) What is the flattest half marathon in Ireland?

The Charleville International Half Marathon in County Cork is officially the flattest and fastest half marathon in Ireland, specifically designed for PB hunting. The point-to-point course is famously straight with minimal elevation gain, attracting the country's top club runners every September who are looking to set national-level times.

3.) What should I eat before a half marathon?

A meal rich in complex carbohydrates and low in fibre, eaten three to four hours before the race, is optimal fuel for a half marathon. A bagel with peanut butter and a banana, or a bowl of porridge work best. The golden rule of performance nutrition is to never experiment with new foods on race morning.

4.) Which is the most beautiful half marathon in Ireland?

The Dingle Half Marathon is consistently voted the most beautiful race in Ireland, thanks to its breathtaking route along the Slea Head Drive. Running along the edge of the Atlantic with panoramic views of the Blasket Islands offers a bucket-list aesthetic that makes the challenging coastal hills feel entirely worth the effort.

5.) What are common mistakes during a half marathon?

The most common mistake runners make is starting too fast and banking time in the early miles, which almost always leads to a significant energy crash. Other mistakes include wearing brand-new shoes on race day, neglecting mid-race hydration, and failing to account for the impact of Atlantic headwinds on coastal routes.
