Behemoth 50k & 25k

Behemoth 50k & 25k is a trail running event in Caldwell, West Virginia, on November 14, 2026. Two distances are offered: the Behemoth 50K (about 31 miles) and the Behemoth 25K (about 15.5 miles), both starting at 7:30 AM. Elevation figures are not published in the listing, so prepare for hills rather than assuming a flat, fast trail; the name alone suggests the organizers are not selling an easy day out.

The 25K is a natural step up from a trail half marathon, while the 50K is a classic first ultra distance. For either, build a 12- to 16-week block with a weekly long run on trails, add back-to-back weekend runs for the 50K, and practice hiking uphill efficiently. Test your fueling on long runs, since a 50K will keep you out for several hours. With a shared 7:30 AM start, a headlamp is not needed, but layers you can shed after the first miles are worth packing.
