North Fork 50

50 Mile | 50K

Buffalo Creek
Buffalo Creek Rd, Pine, CO

The North Fork 50 Mile/50K is 100% trails, mainly single track and some double track, starting and finishing along lovely Buffalo Creek, in the mountains about 50 miles southwest of Denver.

This is a pure ultra, a very special and unique race, deliberately kept small so each runner gets personal attention.

There are no non-ultra distances and no crowds on the beautiful trails.

*Distances may vary slightly each year due to permitting.
