With approximately 21,000’ of vertical gain that includes monster climbs and the solitude of single-track ridge running, the Grindstone 100-mile race is considered by many to be the most incredible ‘hundo’ east of the 100th meridian.

100M

Offering 11,000’ of vertical gain, adventure awaits as you experience some of the most scenic and challenging sections of the 100-mile course in this 100K version of Grindstone by UTMB.

100K

With just over 5000’ of climbing, the Grindstone 50k offers a challenging and scenic course combining gorgeous single track with some fire road running as you get a little taste of both 100k and 100-mile courses.

The Grindstone half marathon course throws a killer climb, a fun ridge run, and a bombing downhill at you, all while still offering a blazing fast start and finish for those interested in a little taste of everything!
