50 kilometers (???) of primarily groomed forest trails. The course consists of three repeats of a 10-mile loop, with a short loop at the beginning to make it 50km, more or less. If you don't like the recommended course, just run anywhere you want to - this is not a real event. We will not generally hang streamers, but hope to mark the two or three important turns. The trails are well-blazed. Any markings will be taken down by the third loop. So pay attention and learn on the first two loops.
