About

The Weld Your Mettle Running Festival takes place in Eaton, Weld County, Colorado, in late May, and offers running and rucking events for every level. The lineup includes a 100 mile, a 100K (62.1 miles), a 50 mile and a 50K (31.1 miles), all starting at 6:00 a.m., then a marathon (26.2 miles), a 14 mile and a 7K walk or run (4.3 miles) at 8:00 a.m.

The setting is a private 146-acre property with views of Longs Peak, where participants race on a dirt loop. The festival offers glamping, camping, a sauna, cold plunges, bonfires, food, drinks, film screenings and plenty of time to socialize, which creates a community feel for runners, friends and families. Check the weather, since Colorado's Front Range can swing from warm to cold in late May.
