Buffalo Creek, CO
The North Fork 50 Mile/50K takes place on the beautiful singletrack trails of the Buffalo Creek Recreation Area, about 50 miles southwest of Denver. Starting at an elevation of 6,700 ft. above sea level, runners will enjoy a variety of terrain in the Pike National Forest, including shady evergreens, burn-scar from the 1996 Buffalo Creek fire, and blooming mountain wildflowers that explode with color!
This is a classic mountain ultra, run 100% on soft-surface trails (primarily singletrack with just a few miles of doubletrack/4WD road), with a max elevation of 8,500 ft. 50 Mile & 50K runners will climb a total of 6,600 ft. & 3,900 ft. respectively, and will be well supported by 9 aid stations throughout the race.
