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**.

How It Works
**Summit, descend, repeat** to reach the elevation equivalent of your event’s namesake mountain. **Hike or run** solo or in the **FlexRelay format** with your trail buddy or trail family. **Self-manage** your rest, pace, fuel, and hydration—it’s all part of the challenge.
