The 10 Best Running Trails in Iceland

Running Culture in Iceland

While Iceland may not be known as a major running destination, the country’s sporting culture is surprisingly rich and growing rapidly. The people of Iceland, known for their strong connection to the outdoors, have taken on trail running as part of their fitness routines and lifestyles. Trail running is an increasingly popular sport worldwide, and Iceland is no different.

Running is particularly popular in Reykjavik, the country’s capital, where both locals and tourists run along the many coastal and city trails. The city has an active running scene with clubs, groups, and events happening all year round. The annual Reykjavik Marathon is a big highlight of the local running calendar, attracting thousands of participants worldwide. However, what sets running in Iceland apart is the opportunity to leave the urban environment behind and practice this sport in a unique environment.

The Best Running Trails in Iceland

Iceland has a large network of trails suitable for walking and running. These trails vary in difficulty, scenery, and length, but all promise an unforgettable experience.

1. Laugavegur Trail

The Laugavegur Trail is probably one of the most famous trails in the country and arguably one of the most beautiful in the world. The trail is 55 kilometers (34 miles) long and goes from Landmannalaugar to Þórsmörk, taking you through a variety of landscapes that make you feel like you’ve crossed into different worlds.

You’ll run across vibrant rhyolite mountains, black volcanic sands, bubbling hot springs, and green valleys. It’s not an easy route, with steep climbs and descents, but the incredible scenery makes up for it. The trail is accessible only in summer, from late June to early September. It’s a great option for experienced runners.

2. Reykjavik Coastal Trail

For those staying in the capital and looking for an easy trail, the Reykjavik Coastal Trail is the perfect choice. This path runs along the bay that surrounds the capital, with great views of the ocean and nearby mountains. It’s not as wild and rugged as other routes, but it provides a great running experience with opportunities to explore nearby parks, art installations, and the famous Sun Voyager sculpture. It’s a great option for those who want to run while exploring or staying in Reykjavik.

3. Esja Mountain Trail

Another great option near Reykjavik, but a bit more challenging. Mount Esja is located just 30 minutes outside the capital, and it’s a popular hiking and running destination, with trails that wind their way up the mountain. The first part of the trail is relatively easy, but as you ascend, the terrain becomes steeper and rockier. Runners who make it to the top are rewarded with panoramic views of Reykjavik, the ocean, and the surrounding countryside.

4. Heiðmörk Nature Reserve

Heiðmörk is a stunning nature reserve also found close to Reykjavik, with a variety of trails perfect for running. This area is known for its pine and birch forests, lava formations, and peaceful lakes. The trails here range from easy to moderate, making them suitable for runners of all levels. In addition to the natural beauty, the reserve is home to many species of birds, which adds a nice touch to the run.

5. Þórsmörk Valley

We now move to one of the most dramatic trails in the country, nestled between three glaciers. The valley is a runners’ paradise, as it has a network of trails that go through green valleys, over glacial rivers, and with fantastic views of the surrounding glaciers. The terrain can be tough at certain points, with rocky paths and occasional river crossings, but the scenery is worth every step. The sense of isolation and wilderness here makes it one of the most rewarding running destinations in Iceland.

6. Skógafoss to Fimmvörðuháls

This iconic trail starts at Skógafoss, one of the most famous waterfalls in Iceland, and ends up at Fimmvörðuháls, a pass between the glaciers Eyjafjallajökull and Mýrdalsjökull. This route is 25 kilometers (15 miles) long and it’s quite challenging, with significant elevation gain. On the other hand, the diverse landscapes you’ll run through make it one of the favorites among trail runners and hikers. You’ll pass by many waterfalls on this route, each one more beautiful than the last, and the view from the top is unbeatable.

7. Skaftafell

Skaftafell, located inside Vatnajökull National Park, is another fantastic destination for trail runners. The area is home to various trails, ranging from easy loops to more challenging routes. One of the most popular ones in the park is the trail to Svartifoss, a stunning waterfall surrounded by black basalt columns. The trail then continues through beautiful valleys, with great views of the massive Vatnajökull glacier, the largest glacier in Europe. In this area, you can find routes suitable for all levels.

8. Reykjadalur Valley

This area is perfect for runners who want a unique Icelandic experience. Here you can find the Hveragerði Hot Spring River Trail, that takes you through a geothermal area filled with steaming vents, bubbling mud pots, and hot springs. The trail is moderate in difficulty, with a few steep sections. However, it offers the chance to end your run relaxing in a natural hot river surrounded by a volcanic landscape.

9. Álftavatn to Hrafntinnusker

This portion of the Laugavegur Trail is often considered one of the most beautiful sections. The 12-kilometer (7.5 miles) trail takes you through a remote landscape with views of glaciers, volcanic deserts, and colorful mountains. The trail is challenging, with significant elevation gain, but the scenery is unlike anything you’ve ever seen.

10. Hornstrandir Nature Reserve

If you go to the Westfjords, one of the most untouched and isolated areas in Iceland, this zone offers a remote and wild running experience. This reserve can only be accessed by boat, as there are no roads leading here. The trail goes along the stunning cliffs and fjords, and there are chances to spot the Arctic fox. The terrain is challenging, so it’s best suited for experienced runners looking for a true adventure.

Famous Trail Races in Iceland

If running for you is not just a hobby to do in your free time, Iceland has some cool running competitions you can join.

Laugavegur Ultra Marathon

The Laugavegur Ultra Marathon is one of Iceland’s most prestigious and challenging trail races. It covers the entire 55 kilometers of the Laugavegur Trail. The race is held in July when the weather is at its best, and the trail is open, but conditions can still be unpredictable. It’s a bucket-list race for trail runners from around the world.

Reykjavik Marathon

The Reykjavik Marathon, held every August, is one of Iceland’s largest and most popular running events. It’s primarily a road race, but the marathon also includes scenic sections along Reykjavik’s coastline, providing beautiful ocean views and nearby mountains. The event attracts thousands of runners, both locals and international visitors, and includes different distances, from a full marathon to a 10K. The atmosphere is electric, with live music, cheering crowds, and post-race celebrations.

Fire and Ice Ultra

For those looking for a serious challenge, the Fire and Ice Ultra is one of the toughest races in Iceland. This multi-day marathon covers 250 kilometers (155 miles) of some of the most remote and rugged terrain in the country. Runners must carry all their gear, including food and sleeping equipment. The route goes through volcanic craters, lava fields, and glacier-covered mountains. The race is known for its extreme conditions, so it’s a test of endurance and mental toughness.

Mount Esja Ultra

The Mount Esja Ultra is a mountain race that takes runners up and down the steep trails of Mount Esja. The race offers various distances, with the longest being 42 kilometers. The race is popular among local runners and is known for its tough, technical trails.

Hornstrandir Arctic Marathon

The Hornstrandir Arctic Marathon is one of the most remote and unique races in Iceland. It’s held in the isolated Hornstrandir Nature Reserve, an area we explained before. The race is not for the faint of heart, as it requires self-sufficiency and careful navigation through rugged terrain. However, for those looking for a true adventure, this marathon offers an unparalleled running experience in one of Iceland’s most beautiful and secluded areas.

The Impact of the Weather on Trail Running in Iceland

Iceland’s weather is unpredictable, and each season has unique challenges and opportunities for trail running. Here’s a breakdown of what to expect during each time of year.

Spring (April and May)

Spring in Iceland is a transitional period. At higher elevations, there is still snow left from the winter, and some trails are muddy. Temperatures range from 0°C to 10°C (32°F to 50°F), with frequent rain and wind. Trails in low-altitude areas near Reykjavik may be clear, but many trails in the Highlands remain inaccessible until late spring. The increasing daylight hours, however, make it a great time to explore without the summer crowds.

Summer (June to August)

Summer is the best season for trail running in Iceland, with mild temperatures between 10°C and 15°C (50°F to 59°F) and long daylight hours. The Highland trails are open, and conditions are generally good and comfortable. Having said that, Iceland’s weather can still change quickly, so be prepared for rain or wind at any time. This is also peak tourist season, so popular trails can get crowded.

Autumn (September and October)

Autumn brings cooler temperatures, ranging from 5°C to 10°C (41°F to 50°F), and the landscape transforms with stunning fall colors. However, daylight hours get shorter each week, and highland trails may close by mid-September due to snow. The weather is similar to spring, with frequent rain and winds, and some areas may experience early snow, especially in the mountains.

Winter (November to March)

Winter in Iceland is challenging for trail running, with temperatures ranging from -5°C to 5°C (23°F to 41°F), snow, and limited daylight. Many highland trails are inaccessible, but coastal paths, especially near Reykjavik, remain open. Snow, ice, and strong winds make traction devices and proper winter gear essential. This season, though, offers the opportunity to see the Northern Lights, and running below them is an amazing experience.

What to Pack for Trail Running in Iceland

If you are an experienced trail runner, you probably know what items you need to enjoy your trip. However, Iceland has particular features that require some special equipment. The country’s unpredictable weather and challenging terrain mean you must be well-prepared for anything.

• Trail running shoes: Iceland’s trails are often rocky, muddy, and uneven, so a sturdy pair of trail running shoes with good grip is essential. Waterproof shoes are a good idea, as you’ll likely encounter wet conditions or you may need to cross a river.
• Waterproof jacket: Iceland's weather can change rapidly, and it’s not uncommon to experience rain, wind, and sunshine all in one run. Therefore, a lightweight, breathable, and waterproof jacket is needed.
• Thermal layers: Even in the summer, temperatures in Iceland can be cool, especially at higher elevations or in the early morning and late evening. Pack moisture-wicking thermal layers to keep yourself warm without overheating during your run.
• Hydration system: Whether you’re running a short trail or a long, remote route, staying hydrated is key. Consider bringing a hydration pack or water bottles.
• Snacks and energy gels: Trail running in Iceland can be physically demanding, so it’s important to keep your energy levels up. Pack energy bars, gels, or other snacks to keep your energy levels high.
• GPS device or map: Many of Iceland’s trails are well-marked, but some areas have no phone signal. A GPS device or physical map can help you stay on course, especially if you’re running in more remote locations.
• Sun protection: Despite Iceland’s cool climate, UV rays can be surprisingly strong, particularly in the summer. The sun reflected on ice or snow can also be particularly harmful. Pack sunscreen, a hat, and sunglasses.

Travel Tips

When planning your trail running adventure in Iceland, a little preparation can make a huge difference.

• Best time to go: All seasons offer their pros and cons. It’s true that the optimal time for trail running in Iceland is during the summer months, from June to September. During this period, the weather is milder, there are long daylight hours, and all the trails are open. However, remember that Iceland’s weather is notoriously unpredictable, so be prepared for rain and wind at any time of year.
• Accessing trails: Many of Iceland’s best trails are located in remote areas, so renting a car is the best way to get to them. If you’re planning to go to the Highlands or more rugged terrain, consider renting a 4x4 vehicle.
• Accommodation: For multi-day trail running adventures, a good idea could be staying in one of Iceland’s many mountain huts or campsites. The Laugavegur Trail, for example, has huts along the route where runners can rest and spend the night. If you are going during peak season, think about booking in advance.
• Respect the environment: Iceland’s natural landscapes are fragile, so it’s important to help preserve them. Stick to marked trails, avoid disturbing wildlife, and pack out all your trash to help preserve the environment.
