The course is going up or down most of the time with only a few stretches that are flat. Equal ascent/descent of approximately 14,000’. Some of those hills, primarily on the 70% which is smooth gravel road, are quite steep. 27% of the course is on single track trail or jeep road, with only a small amount of that being lumpy.
Basically the footing is quite good overall. About 3% is on 5 segments of paved road, with the longest of those being 1.0 mile long. The last 30 miles are rather challenging.
