Mammoth Cave 50K/25K

🏃‍♂️ Race Overview

Join us for the 5th running of Mammoth Cave 50K/25K trail race on Saturday, October 25, 2025, in beautiful Mammoth Cave National Park!

Named after the historic railroad that once roared through Mammoth Cave National Park from 1886 through 1931, the Bike & Hike Trail provides a scenic, wooded experience within the Park on a crushed gravel surface. The out-and-back trail offers some challenging ascents/descents along its scenic route, and is perfect for the first-time trail runner or racers looking to set a lightening fast PR!

🌲 Course Details

Understand this is a trail race. We are limited based on where the trail goes. So unlike a road race, the distance is never exact. This is common knowledge to most everyone who has run trail races in the past, but it never fails and there is always one who is upset that their GPS watch showed 16.5 miles when the race said it was a 25K. Everyone is racing the same course: therefore, it’s an even playing field.

This will be a "cupless" race. Runners will need to provide their own collapsible cups, bottles, or hydration packs for refill at the aid stations.

COVID precautions & safeguards may be enforced based on CDC guidelines at the time of the event.
