MammothMarch is back at Cuyahoga Valley National Park!
We are excited to welcome back hikers from all across the country for one of the most iconic hiking events in the US: Our unique National Park edition, MammothMarch Cuyahoga Valley 2026, will take place on September 20.
20 challenging yet scenic miles will once again lead along beautiful trails, such as Wetmore Trail, Valley Trail, Salt Run Trail and Ohio & Erie Canal Towpath.
Make sure to secure your tickets as we expect the event to sell out fast again.
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!
