STHLM Loop

STHLM X is the race that changes shape every year – the 2022 concept is STHLM Loop! STHLM Loop consists of a starting area, four loops (from 2.1 to 6.7 km) and a total of ten starts (laps) over five hours, with a new start every half hour. You choose which loop you want to run and how many laps you aim to participate in. How fast you run each lap determines how long you get to rest before the next lap begins. More info on the website.
