Organizer's Description
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.
