Date: Saturday, May 3, 2025

Location (start/finish): Fall Creek Falls State Park, 2009 Village Camp Rd, Spencer, TN 38585

Distance: 20 miles in 8 hours There is no timekeeping, there are no failures, we only recognize the incredible courage it takes to rise to our challenge. Every participant completing the distance will be awarded their finisher medal and considered a winner!


Starting time: You can choose from several time slots as early as 6:45 am with limited capacity when signing up. This ensures the most remote hiking experience as a maximum of 5 hikers will cross the starting line at the same time. The first ones will head out between 6:45 – 7:00 a.m. with the majority coming back in just about 8 hours. However, we will have our finish line open a little bit longer for the ones that need a bit more time – cut off time at either aid station will be sunset (meaning if you’re hiking at a pace that won’t let you finish before sunset, we will provide a shuttle service back to the venue).

Parking: Complimentary parking will be available on site.

Accommodation: Secure a discounted room at the modern Lodge at Fall Creek Falls right here. You can also give reservations a call and mention our MammothMarch group code “36159“. Phone numbers are 423-881-2001 or 423-881-2002.


Aid/refreshment stations: There are water stops and aid stations along the route (approximately positioned every 5-7 miles apart) providing toilets, food, and drinks for all participants. These refreshments are included in the cost of your ticket and vary between each station, offering water, energy drinks, electrolytes, fruits, cereal/protein bars, sandwiches and more.

Certificates: All finishers will receive their personalized certificate after crossing the finish line. For the ones who drop out, we will issue certificates stating the mileage covered.

Finisher medal/wall of fame: For all participants finishing MammothMarch.

Merchandise: Our 2025 merchandise collection will be available later in 2024.
