We Bring the Highest Mountains to You!

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.
  • All Mountain Athletes show up Friday evening. You will set up your tent in the base camp right off the course with other Mountain Athletes and tenting spectators and all events in the series start at 7 am sharp on Saturday morning. This is an all-weather event.
  • We provide the mountain, parking, basecamp, spectator areas, restrooms, facilities, electronic timing, custom and personlied bibs, bib belts, and a beastly blinged-out finishers’ medal for Individuals, Trail Buddy FlexRelay, and Trail Team FlexRelay teams!
  • Hike it, run it, alone or together, or in our unique FlexRelay format with your trail family.
  • Rest when you need to.  Eat and water up when you need to.
  • This is your extreme mountain long-haul to manage and conquer!
  • There are four events in the IronHike Endurance Series:
  • 12-hour single-day 15-miler, 48-hour 43-miler, 72-hour 62-miler Everesting Trek and the holy grail of Ultra, our 84-hour, 72,000 feet of elevation gain and loss Ultra, named Olympus Mons after the highest mountain in the solar system on Mars!
  • You versus you, you versus the mountain.  Prove yourself right about you!  You will be in great company with your new tribe of mountain athletes.
