Your Guide to the 2026 Sea Ice Marathon in Luleå

Only a few months left until the coolest marathon in the world. On 22 February 2026 you finally stand on the frozen Gulf of Bothnia with runners from many countries. You run on natural sea ice which makes this race feel different from any road marathon. The open landscape, the cold air and the shifting surface create a challenge that keeps you sharp from the first step to the finish line.

Make sure you prepare with the right clothing and footwear. Spiked shoes give you the stability you need on the ice. Follow the weather forecast in the days before the race so you can adjust your outfit and stay comfortable. Enjoy your training and keep your focus in the final weeks.
