Mountain weather is part of the Event. Pack for it. Plan for it. Earn it anyway.
What is an IronHike Series?Just the nitty gritty... Getting up there and back down.
- ▲Four Signature Mountains drive 7 Events across 3 formats. From a 12-hour entry point to one of the world's top ultra endurance experiences. Something for every level, every shape, every skill set. First-time Mountain Athlete or seasoned ultra veteran, there is an Event with your name on it.
- ▲Register Solo, as a Trail Buddy pair, or as a Trail Family of up to 4. The FlexRelay format means teammates share laps. You go when your teammate rests. Everyone earns the same summit.
- ▲Base camp is yours for the duration. Tenting, fire pit, hydration, and Tribe camaraderie included. The Cadre treks every Event alongside you.
- ▲This is not a race. There is no finish line, no podium, no age group awards. The Cadre rings the Final Bell. What you earned between the start and that bell is yours forever.
- ▲Every Event starts at noon except the two 84-hour Events, Olympus Mons and Answer the Bell Full, which start at midnight. You set up camp, meet your Tribe, and get your bearings. Then the mountain opens and you go. Lap after lap, summit after summit, through daylight and dark, until the Final Bell rings or you choose to stop. The Cadre and your Tribe are with you every step.
