There's a lot of important information in the race manual for the Salomon Xreid Hardangervidda, but here's a note that will particularly catch your eye: "The route will be changed if there is a conflict with the wild reindeer population."
The 150-km mountain run takes place in the remote Hardangervidda National Park in Norway, on Europe's biggest mountain plateau. The training ground for Arctic adventurers is remote and beautiful – but harsh. Cold temperatures and wind must be dealt with year round. Xreid runners traversed trail and stream (and of course avoided the reindeer) during an epic trail run. Check out the pics below.
