Park City, United States • 25 Oct 2025

The Mammoth Cave 50K/25K is a trail running event held in Mammoth Cave National Park, Park City, Kentucky. Scheduled for October 25, 2025, it features two distances: a 50K and a 25K. The race takes place on the scenic Bike & Hike Trail, a crushed gravel out-and-back route named after a historic railroad, offering wooded surroundings with challenging ascents and descents.

The event is suitable for both first-time trail runners and those seeking a fast personal record. There is a strict 8-hour cutoff for both distances, and the race is "cupless," requiring runners to bring their own hydration gear. Registration is limited due to park restrictions, and no refunds or deferrals are allowed. Visit the organization's website for the most recent information.
