Organiser's Description
Join us for the 4th running of MAMMOTH CAVE 50K/25K trail race on Saturday, October 26, 2024, 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!
The race will start at 7:00 AM (Central), for both distances, from the Bell's Tavern Pavilion in Park City, KY, and will end by 3 pm. A HARD CUTOFF OF 8 HOURS WILL BE IMPOSED FOR BOTH DISTANCES.
Pricing:
*
Those who register on opening day (April 15th) will receive last years pricing ($85 for the 50K, $65 for the 25K).
*
The very next day (April 16th), pricing will INCREASE to $95 for the 50K and $75 for the 25K.
*
Fees will then increase to $105 (50K) and $85 (25K) on September 1st for any remaining spots.
All runners will receive a t-shirt if they register by 9/1/24. We will order extra shirts but we cannot guarantee that we will have your size.
Due to National Park restrictions, registration will be capped. At present, we are opening registration to 150 runners, with the hopes of increasing pending permit approval. Based on demand, we may open additional spots in the 50K distance by eliminating open spots in the 25K, or vice versa and adjust as needed.
_THIS EVENT SELLS OUT QUICKLY!_
_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 time of the event.
