MammothMarch Texas ​​​
​
MammothMarch is coming to the Lone Star State!
​
We will welcome you for an unforgettable hiking adventure in one of the most fascinating and scenic State Parks in Texas: Dinosaur Valley. Our 20-mile, single-circuit hiking route will put every inch of the Park’s beauty on full display, including its hilly, hardscrabble limestone terrain, multiple diverse trails, and the Paluxy River. ​
​
Explore where 113 million years ago, dinosaurs left footprints in the mud at the edge of an ancient ocean and walk their tracks in the bed of the Paluxy River. ​ ​
​​​Dinosaur Valley State Park is located less than 90 minutes southwest of Dallas/Fort Worth and less than 3 hours northwest of Austin. It not only features our beautiful 20-mile hiking route but also options to camp, picnic, mountain bike, swim, fish, paddle in the river, watch for wildlife, ride your horse, or visit the Park’s interpretive center, all which makes for an unforgettable weekend getaway.
Master the challenge and spend a beautiful day hiking 20 miles at a stretch. Getting your finisher medal, you will be exhausted but proud and happy... as well as part of our amazing community of nature-lovers, hikers and MammothMarch addicts!

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 7:00 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 7:00 a.m. – 7:15 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.
​
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.
​
Hiking Pass: MammothMarch Hiking Passes will be made available for all new participants. All participants from previous editions or different MammothMarch events should bring their Hiking Pass to collect their 2025 stamps on site.
​
Merchandise: Check out our Texas event store right here. Our full 2025 merchandise collection will be available later in 2024.
​
Route: The single-circuit loop will cover 20 miles along beautiful and scenic trails inside Dinosaur Valley State Park, including the Cedar Ridge Trail, Buckeye Trail, Paluxy River Trail, Denio Creek Warbler Trail & more. The final route will be made available around 2 weeks prior to the event.
​
Total elevation gain: Around 1,400 ft.
Terrain: Mainly unpaved hiking trails, rock/dirt trails, horse trails, gravel roads and forest floor.
