Spartan Race World Championships took place yesterday at the iconic Squaw Valley in Lake Tahoe, California. The race brought athletes in from all over the world, in total about 20 countries where in attendance. The first seven miles of the course were a climb up to the peak of Squaw Valley, and it was immediately clear that experienced mountain runners would have an advantage. Robert Killian quickly surged into the lead on the men's side, a position he would not relinquish for the remainder of the day.
