 No podium. No records. No age group awards. Your only competition is yesterday's version of you.

The Mountain keeps no score. You finish what you finish. That's enough.

Your first summit or the hardest endurance Event on Earth. Both live here.

IronHike is a veteran-owned elevation-based endurance event Series and New England's premier vertical trail endurance event Series. No lifts. No shortcuts. No gondola. Earn every up and every down. The self-powered Everesting alternative on the East Coast — where you earn every descent.

If you've done 5Ks, half marathons, or weekend hikes and keep asking what's next — this is what's next. No running required. If you can walk up a mountain repeatedly, you can do this.

You won't go up alone. The Tribe is already there — at 2 AM, at the base, on the trail. Shared suffering builds something that finish-line medals don't.

 "The descent is harder than the climb. The mental battle is the real deal."

— Marcus · IronHike Denali Finisher

 Fall 2026 | When and Where

For four days, October 1–4, 2026, we rent Mohawk Mountain Ski Area in Cornwall, Connecticut, so you can conquer IronHike. Fall in the Litchfield Hills means peak foliage, crisp mountain air, covered bridges draped in color, and farm-to-table harvests minutes from the Mountain. October is when the Mountain is at its most dramatic, and so is the Mountain Athlete in you.

 What to Know

Mountain Athletes' Guide — Mohawk Mountain

Everything you need to know about the course, the venue, training, gear, and what to expect on the Mountain.

 Read the Mountain Athletes' Guide

The FlexRelay Format

Each team member in the Trail Buddy or Trail Family Event has no minimum or maximum laps, mileage, elevation, or time on the course. Teams manage who is on the Mountain for how long and when, according to conditions, fitness levels, and the needs of the team.

Common Questions

Do I need to be a runner? No. IronHike is a hiking Event. If you can walk up a mountain repeatedly, you can do this. Running is never required.

What if I can't finish? The Mountain keeps no score. Every lap is earned. Every Mountain Athlete sets their own ceiling — the Event ends when you decide it ends, or when the Final Bell rings.

Cancellations, Deferrals & Transfers

Policy: No refunds, deferrals, or transfers between Series. Upon request, you may receive an 80% credit toward any future Event (no expiration). All sales final.

If you are unable to attend, we can provide a single-use coupon for 80% off any future registration with no expiration date. Transfers within the same Series are allowed on a case-by-case basis.

We produce elevation-based endurance events and multi-day mountain endurance events at Mohawk Mountain Ski Area in Cornwall, Connecticut. The Mohawk Mountain endurance event Series runs Spring and Fall each year. Our FlexRelay format lets Mountain Athletes compete Solo, as a Trail Buddy pair, or as a Trail Family of four. This is not a race endurance event. There is no podium, no finish line prize, and no gondola. Every foot of elevation gain is self-powered, earned one lap at a time, by athletes from 30 states and 3 countries and counting who came here to prove themselves right. The Events

IronHike offers seven elevation-based endurance events ranging from a 12-hour endurance event to an 84-hour endurance event, covering 7,140 to 72,590 feet of vertical gain at Mohawk Mountain in Cornwall, Connecticut.

We are the leading 29029 alternative and Barkley Marathons alternative in the USA, and the Olympus Mons Ultra is ranked as one of the hardest ultra events in the world and the hardest endurance hiking event in the USA. The Answer the Bell Ultra is a backyard ultra on a mountain and a last person standing ultra. Our FlexRelay team endurance event format makes multi-day ultra endurance and vertical trail endurance accessible to athletes at every level. The Tribe

The IronHike Mountain Athlete Tribe is a shared suffering endurance community built from the ground up by veteran endurance sports athletes who believe that personal transformation happens on a mountain. Athletes from across the country and beyond register as Solo Mountain Athletes, Trail Buddy pairs, and Trail Family teams to earn every foot of elevation together. The IronHike Tribe spans 30 states and 3 countries and counting, supported by the veteran-owned Cadre who trek every Event alongside them. You show up, you belong, and you prove yourself right one lap at a time. What Makes Us Different

IronHike is a self-supported mountain ultra Series where every foot of elevation gain is earned under your own power. No gondola, no lift, no shortcuts. As a veteran-owned endurance event operating at Mohawk Mountain Ski Area in Cornwall, Connecticut, IronHike delivers East Coast ultra endurance at a level that rivals the hardest events in the world. We are the most affordable Everesting alternative and the most accessible 29029 alternative on the East Coast.
