Join the Ice Age Trail Alliance for the 2026 Mammoth Hike Challenge!
Spend October outside! On the Ice Age Trail. In Trail Communities. At events.
Discover Wisconsin’s wild beauty, support Ice Age Trail Communities, and take on 46 miles of adventure to earn a certificate and limited-edition patch celebrating your accomplishment.
Accumulate miles solo, as a pair, with a group, on a team. Hike, walk, backpack, run, skip, craw, saunter, it’s up to you! Log your miles and Trail Community visits over days, weekends, weeks, or one big adventure. However, you choose to do it, you'll finish October with unfortgettable adventures, new discoveries, and a patch you've truly earned.
