We bring the highest mountains to you. No podium. Just proof.
An elevation-based Series of 7 Events in Solo, Trail Buddy, or Trail Family FlexRelay formats, at varied elevations, lengths, and distances. All run, hiked, or power-hiked by Mountain Athletes from all over the world, on a real mountain course or a staircase, with one common goal: crush the damn mountain while pushing hard on personal limits.
💬 "Growth hides in discomfort, and in the pain most people avoid. That's what's so special about IronHike Events. It forces you into rewarding suffering, surrounded by a Tribe of people who choose to prove themselves right."
— Isabelle · Age 17 · First-Ever Answer the Bell - Basic Finisher

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.
