Ultra Marathon

Ultra Marathon Iceland Challenge - is a private two-day run & hike challenge organized by British travel company Action Challenge and hosted by Iceland Challenge DMC. 

​

Held from 10–13 July 2025 in South Iceland, near the Selfoss area, the event was designed exclusively for a selected group of participants and offered a total of 84 kilometers of running and hiking across Iceland’s extraordinary natural landscapes.

​

Participants completed 42 kilometers per day, traversing highland trails, lava fields, moss-covered valleys, hot springs, thermal rivers, volcanic lakes, glacial basins, and colorful rhyolite mountains in remote wilderness areas. A highlight of the route was a marathon starting from Þingvellir National Park, allowing runners the rare experience of crossing the geological divide between the North American and Eurasian tectonic plates.

​

The routes were developed specifically for this challenge by the Iceland Challenge team, requiring over 100 hours of hiking and route testing to ensure a perfect balance between adventure, safety, and visual impact.

Full logistics and infrastructure — including basecamps, route marking, support vehicles, rest stops, and accommodation services — were handled by Iceland Challenge DMC. The operational team included 15 professionals ranging from project managers and route specialists to drivers, cooks, and field assistants.

​

Trusted partners for this event included Gray Line Iceland, Keahotels, Fontana Spa, and Midgardur by Center Hotels.

The Ultra Marathon Iceland Challenge was amazing and unforgettable experience for all participants.
