Description

The Mountain Bike start is 7 a.m. at the 1A Base Area of Aspen Mountain, located at S. Aspen St. and Gilbert St.

Riders will launch directly into a sustained 3,300 ft. climb over 5 miles, ascending the Summer Road (CR -14) to the summit of Aspen Mountain. AID #1 will be distributed here, as well as, an enforced 9:00 AM CUT-OFF.

Departing the Ski Area boundary riders set off over a rolling traverse on Richmond Ridge Road (CR-15E).

At mile 9.5, riders begin their second sustained climb of 1,292 ft. over 3.4 miles. After an intervening 300 ft. descent, leading back into a 300 ft. climb, followed by another 300 ft. descent, racers arrive at AID #2 (mile 16.8) and the Taylor Pass Checkpoint. A 11:30 a.m. CUT-OFF will be imposed.

Riders continue on a moderate doubletrack descent for 4.5 miles. At mile 18.3, the route begins an alpine ascent to the top of Star Pass, and the doubletrack transforms into singletrack at mile 20.5. Once over Star Pass, riders embark on a relentless 11.4 mile descent down the Brush Creek drainage.

Singletrack turns back into doubletrack at mile 23.4 (FS Road 738.2B). Continuing to mile 28.5, riders will divert off the jeep road, forking to the south (LEFT) onto the Death Pass singletrack traverse, a narrow off camber section skirting a steep escarpment. Take caution on this exposed section! Arriving on the opposite end of the singletrack, riders continue STRAIGHT, regaining the doubletrack road (FS Road 738.2B)

The road descends briefly, crossing a cattle guard, soon leading to the wide, West Brush Creek crossing. Immediately after the water crossing, the road gently climbs on a cross slope trajectory. The top of this climb opens into a meadowed area with numerous dispersed campsites. CAUTION - vehicular traffic becomes a hazard from here until AID #3. The route continues onto a sustained descent to the valley floor where doubletrack transitions to dirt grated Country Road 738. The course continues down valley on level road surface, until crossing over the East River bridge, the road begins a 0.25 miles climb up to AID #3 (Mile 35.8) Riders unable to depart this check point by 2:30 p.m. will be CUT-OFF and asked to ride themselves into the Town of Crested Butte via Brush Creek Road to Hwy 135.

Departing AID #3, the route returns to singletrack (FS Trail 435.1 - “Upper Upper Trail”), presenting racers a 470 ft. stinger over 0.5 miles. After twisting descents through the “bridges” section of the Upper Upper trail, riders will continue on to their last climb, ascending through a technical rock section. This last 700 ft. climb over 1.4 miles tops out at Hunter Hill Road.

Intersecting pavement, racers bare to the RIGHT, following course marking to the San Moritz condo parking lot connecting to the San Moritz singletrack trail. This trail propels racers on to a descending finish at the base of Crested Butte Mountain Resort.

This is my new favorite. It has tons of steep climbing and descending. It has long sections of remote alpine terrain and forests too. Incredible. 39mi — 6h 50m

Really hard start going up Ajax but super fun after that, even after having run the trail the day before.

There are so many options to ride around here - this one is not worth the time. Seems like better for motorcycles than mountain bikes. Too many hike a bike steeps and lose rocks. Only fun section was on descent after Star Pass. Riding from base of Aspen Mountain is a long slog followed by more slow climbing and walking til peak Star Pass. Sep 15, 2018
The Grand Traverse route epitomizes a Rocky Mountain mountain biking adventure. It has alpine terrain, forests, stream crossings, steep sections where one pushes the bike, a fast descent, incredible vistas and aspen groves, jeep roads and single track. It gives one a taste of remoteness and the seriousness of the Rocky Mountains. Bring some fitness and a grin when you really want to grimace. Sep 29, 2018
