These are high altitude races, with lots of climbing, in the scenic foothills of the Eastern Sierra Nevada. The course is mainly run on 4 wheel drive dirt roads, with a couple of sections of single-track trail, and very short sections of pavement. There are very few trees, thus the race is exposed, often hot, usually dry, sometimes rocky, and mostly high! Much of the 100k and 50 mile courses are above 7000' in altitude. These races are the perfect training opportunity for upcoming mountain trail ultra distance events.

The weather can range from cold to hot, dry to snowing, breezy to very windy. We have experienced all weather types, but usually we can expect fine, sunny weather, with afternoon breezes and high temps for the second half of the day. Temperatures usually range from high 40's at the start to 90's in the late afternoon, and then cooling in the evening.
