We are excited to be back at Bear Brook State Park!
After our successful New Hampshire premiere in 2024, we are back in the Granite State for round two!
Our scenic 20-mile route leads through the heavily forested park, which includes seldom visited marshes, bogs, summits and ponds – all ready for you to conquer on September 27, 2025. The leaves will start to change, fall colors will be on display and provide a stunning scenery for a beautiful and challenging adventure.
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!

Please note that the route will be made available for download approximately 2 weeks prior to the event. Please note that the route is preliminary and may be adjusted due to weather issues, official directives and/or organizational matters. The route will be marked 1-2 days prior to event day. Should we notice parts of the route being inaccessible, extremely wet/muddy we will of course adapt it to local conditions at short notice.
