Saturday, June 1 I Wompatuck State Park 


Massachusetts, we are back for a second edition of MammothMarch at Wompatuck State Park! Hike 20 miles in 8 hours through one of South Shore’s hidden attractions, located just 20 miles south of downtown Boston. 

June 1 will be the official “2024 National Trails Day”, and we’d like to take you on a journey through everything this undeveloped and heavily wooded State Park with its 3,500 acres of forest, streams and ponds has to offer. 

Mastering our challenge, 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 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 for the ones that need a bit more time. 

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 a previous edition or different MammothMarch events should bring their Hiking Pass to collect their 2024 stamps on site. 

Merchandise: Our 2024 merchandise collection is available right here
