Mammoth Cave 50k/25k
The Mammoth Cave 50K/25K is a trail running event held in Mammoth Cave National Park, Kentucky. Scheduled for October 25, 2025, this race features two distances: a 50K and a 25K, both set on a scenic, crushed gravel trail that offers a mix of challenging ascents and descents. The event is designed for both novice and experienced trail runners.
Registration is capped at 150 participants, and the race is noted for its quick sell-out. Runners are required to bring their own hydration solutions, as the race will not provide cups. Visit the organization's website for the most recent information.
