“The race route for the North Fork 50k.”— Dave Caldwell
Featured Race - Jun 1, 2019
The are several burn areas that are completely exposed to the sun for several miles at a time. Make sure you have adequate sunscreen and a hat!
From the aid station, runners turn onto Charlie's Cutoff to do the 4.8-mile "Charlie's Loop," a fun descent on Charlie's Cutoff and Homestead (right turn) Trail for about half that and then a climb up Miller Gulch (sharp right turn) back to a right turn on Homestead Trail and a second visit to Homestead aid station at 10.1 miles.
Runners then turn around and go back down Homestead to Miller Gulch Trail, turn right and head gradually uphill for just over a mile on Miller Gulch and Gashouse Gulch (left turn) Trails, and then a big downhill begins on Gashouse Gulch to the Buffalo Creek aid station at 14.7 miles.
After 4/10 mile of gradual uphill along Buffalo Creek, the 50K and 50 Mile courses split at 15.1 miles at the junction of Buffalo Creek and Tramway Creek Trails. The 50K turns left up Tramway, and the 50 Mile continues straight along Buffalo Creek. The course climbs up Tramway Creek Trail to the Colorado Trail, where the course turns left. The Colorado Trail section rolls up and down for 3.6 miles, the first half mostly up and the last half mostly down, to a left turn on the Shinglemill Trail, followed by a quick descent to the Shinglemill aid station at mile 20.2 (mile 38.2 for the 50 Mile).
From the aid station, the Shinglemill and Morrison Creek (left turn) Trails take runners back down to Buffalo Creek on a lovely 3.3-mile downhill. A left turn onto Buffalo Creek/FS 543 takes runners on a gentle uphill along the creek to the Buffalo Creek aid station at 24.3 miles.
From Buffalo Creek, the last big 3-mile climb begins up Baldy Trail, followed by a gentle section on Gashouse Gulch (right turn), Miller Gulch (right turn) and Homestead (left turn) Trails, taking runners back for one last visit to the Homestead aid station at 28.4 miles.
The 3.6-mile run from Homestead to the finish in Pine Valley is almost all downhill (just one more short climb!), some of it steep, on Homestead, which becomes Strawberry Jack, and Buck Gulch (right turn) Trails and then along beautiful Pine Lake (right turn), pictured above, to the finish line at the large picnic shelter.
