IronHike Endurance Series 2026–27: Choose Harder. Choose Your Summit.
At Mohawk Mountain, Cornwall, Connecticut & Amicalola Falls State Park, Dawsonville, Georgia, USA
IronHike enters its 4th season after expanding in 2026 to two venues and three Series. With its 2026 Mohawk Mountain Series now complete, the IronHike Endurance Series proudly extends a hearty invitation to Mountain Athletes from around the globe for the three Series on the 2026–27 calendar: Thu–Sun, December 10–13, 2026 on the Appalachian Trail Approach at Amicalola Falls, then Thu–Sun, June 3–6 and Thu–Sun, October 7–10, 2027 back at Mohawk. These Endurance Events are more of a personal odyssey than a competition, beckoning Mountain Athletes to reach the highest summit in their own mind, to choose harder, and to choose their summit.
🌊 The Newest Venue: The Appalachian Trail Approach at Amicalola Falls, Georgia
Amicalola Falls State Park is the Series’ newest venue, home to Georgia’s highest waterfall and the official southern gateway to the 2,197-mile Appalachian Trail. The course is the park’s iconic staircase: 604 stairs down to the Reflection Pool, 604 stairs back up, 1,208 stairs every lap. An Olympus Mons Ultra finisher there climbs 144,960 stairs. Base Camp sits at the top of the falls, the on-site Lodge offers a special Mountain Athlete rate, and Atlanta is about an hour and 15 minutes away.

A Personal Odyssey, Not a RaceThe IronHike Endurance Series strips away the conveniences, pushing participants to rely on their own resilience and determination. It is raw and uncompromising, offering a true test of endurance and spirit.
“There is nothing out there like IronHike. The camaraderie, the shared suffering, the sense of brotherhood. I’ve done Tough Mudders, Spartans, and marathons. Nothing compares.”
— Paul, IronHike Everest FinisherAbout the IronHike Endurance Series, Mohawk Mountain & the Appalachian Trail ApproachFounded by John Kolker (Founder/CEO), a US Army Intelligence Veteran and sudden cardiac arrest survivor, the IronHike Endurance Series is a call to those who seek to redefine their boundaries.
