High Point

The Crested Butte Big Mountain Enduro will encompass 18,000 feet of descending over the course of three days. Expect big days on the bike averaging 21 miles per day, high alpine elevations surpassing 12,500′ and definitely some exploratory hike-a-bike climbs thrown into the mix. The terrain and descents will contain a variety of above-tree line stages, many high speed sections that CB is known for, technical rocky/rooty trails, steep and raw trails that will keep riders on their toes, some classic bench-cut Colorado singletrack, mixed with endless scenery that will leave lasting memories of this rugged mountain paradise. Riders should be prepared with necessary parts, clothing and food, as each day will be deep in the backcountry, with river crossings and mountainous weather that can be threatening at any moment this time of year. This race will be a true test of mental strength, fitness and require a huge sense of adventure to get through all three demanding race days.

mandatory dismount for a downed aspen about halfway down. If i recall correctly, it was on that small climb section, unfortunately, i dont know the trail well enough to give an exact location. other than that though, the trail was in awesome condition. there were a few mud puddles in the woods at the top, but nothing to be concerned about.
