IronHike Endurance Series - Fall 2025
About
We Bring the Highest Mountains to You!
NEW! - IronFest After-Series Celebration - Sunday afternoon, with food, prizes, awards, music, open mic, and more!
We rent a mountain for 4 days to bring you IronHike… The IronHike Endurance Series at Mohawk Mountain is a single or multi-day event that is part hike, part trail run, part group camping trip, part one-of-the-hardest-damn-things-you’ve-ever-done, and full-on badass mountain footslog.
Three ways to IronHike!
1. Go it alone, together.
2. With a Trail Buddy.
3. With a Trail Family.
You do the whole event alone, with a trail buddy, or with 3 other team members who choose to share the mileage and elevation from 12, 24, 48, 72, and/or 84-hour Events. Events may require night trekking by headlamp. Manage your laps and pace in our FlexRelay format. You also manage your rest, food, hydration, and sleep in your tent right off the trail.

You versus who you were yesterday and you versus the Mountain...
The IronHike Endurance Series is part of a new classification of events that combines physical, mental, and spiritual gumption. These are NOT races. There is no Podium, no age group awards, and no records to break. These challenges will change your life! Extraordinary Events for a broad range of fitness and skill levels, from ordinary people to seasoned and elite Mountain Athletes reaching beyond their comfort zones!
Invest in yourself...
Change your story. Do something hard, either for the first time or again! This is about you and the mettle in your own heart. It is about your journey toward becoming the best version of yourself. Each summit takes you closer to overcoming the super-hard and allows you to let this epic experience change you for the better.
What you'll do...
Hike it, run it, alone or together, or in our unique FlexRelay format with your trail buddy or your trail family.
Rest when you need to. You will summit and descend the same mountain until reaching the equivalent elevation of the namesake mountain of your event. This is your extreme mountain long haul to manage and conquer!
Five simultaneous events...
12-hour 15-miler, 24-hour 30-miler, 48-hour 43-miler, 72-hour 61-miler Everesting Trek and the most vertical gain and loss of any Ultra under 200 miles in the world, our 84-hour, 72,000 feet of elevation gain and loss event Olympus Mons Ultra - powered by Skratch Labs ®, named after the highest mountain in the solar system on Mars!
We publish a Mountain Athletes' Guide (MAG) for each Event Series a few months before the Series, with a full detailed schedule.
You can download the latest version of the MAG here
