IronHike Endurance Series - Spring 2025 - Mohawk Mtn, CT, USA

IronHike: The Mountain Comes to You

For four epic days, we rent a mountain—so you can conquer IronHike.

Choose Your Path to the Summit

• Solo – Go it alone, but surrounded by a tribe.

• Trail Buddy – Partner up for shared endurance.

• Trail Family – A team of four tackling mileage and elevation together.

Each event spans 12, 24, 48, 72, or 84 hours, with self-managed pacing, hydration, and sleep in our FlexRelay format.
Some events require night trekking by headlamp.
