50 KM
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 entirely within the Park on a crushed gravel surface. The trail offers some challenging ascents/descents along its 9-mile crushed stone route, and is perfect for the first-time trail runner or racers looking to set a lightening fast PR!
The 50K race will start at 7:00 AM with the 25K race at 8:00 AM. The race is an out-and-back with the 50K runners repeating the route.
