Course: Start and finish at the Green River Lakes Road Parking area and follow the N loop. The racecourse is approximately 28 miles and has 2600 feet of elevation gain and loss.
Section 1: Start to Dollar Lake Aid Station
9 miles and 325-foot elevation gain
Racers will start by heading north along the road following the Green River for about 9 miles to the Dollar Lake Aid Station. This section of the course is fairly flat, wide, fast (pending snow conditions) and easy to follow. If you are struggling here, this is a good place to turn around as it only gets harder from here.
Section 2: Dollar Lake to Moose-Gypsum Intersection
4.5 miles and 300-foot elevation gain
From Dollar lake the trail continues North and then turns East following the river. Watch for and enjoy (but do not approach) elk in this area. At no time are racers allowed to leave the trail, this is a protected area. Your actions reflect this race-follow the rules, and respect any and all wildlife you encounter.
Section 3: Moose/Gyp intersection to Gypsum Creek Aid Station
8.3 miles and 1350-foot elevation gain and 750-foot elevation loss
Racers will turn right on Moose-Gypsum road, shortly thereafter begins the biggest climb of the course. Pay attention to your temperature here, do not soak clothes with sweat or the descent to the finish line will be a cold one!! Racers will gain 1200 feet over the next 4.3 miles to the course high point of 9200 feet. Give yourself a pat on the back, it’s downhill from here…mostly. The course flattens out for about a half-mile before starting a gradual 3.5-mile 600-foot descent to the Gypsum Creek Aid Station, only 6.5 miles from the finish.
Section 4: Gypsum Creek Aid Station to Finish
6.6 miles and 700-foot elevation gain and 1600-foot elevation loss
The course stays flat for about a mile before a 400-foot descent and then climbs over 2.5 miles. Be sure to layer up for a fast 3-mile 1000-foot descent to the finish line!
There are two aid stations. Racers must check in at each aid station. Both will have race volunteers, radio and basic first aid kits. While you may be able to grab a snack and top off your water, you need to be self-sufficient at this race. Do not rely on aid stations for safety, food, water, or major medical needs. This is a cupless race. Aid Stations are mandatory. If you do not stop and check in at an aid station, you will be called in as missing and a search party will be dispatched immediately. Remember cut-off times are strict!
