Race description
A new ultratrail race on Adelsö on 16 May 2027. Adelsö is one of the Mälaren islands on the outskirts of Stockholm. We have worked hard on the course and are proud to present a scenic marathon-distance XL that combines coastline and technical forest trails with 600 metres of climbing. Beyond the natural experience, the race offers a journey through historically significant landscapes, which we have made an effort to highlight along the route. One of the most exciting ultraraces in Stockholm in spring 2027 for those who love trail running.
