Prepare for an unparalleled endurance challenge at the Iron Hike - Spring Denali Ultra Trail Marathon Relay, set to unfold from June 5th to June 7th, 2026, in the breathtaking Northwest Hills of Cornwall, CT. This epic 48-hour event, based at Mohawk Mountain Ski Area, invites participants to run, hike, or walk over 43 miles while conquering a staggering 20,825 feet of elevation gain, aiming to match the vertical ascent of Denali itself. Typical race day conditions in early June offer pleasant highs around 71°F and lows around 52°F, with a modest 21% chance of precipitation, providing an ideal backdrop for this rigorous mountain footslog.
What sets the Iron Hike apart is its unique "FlexRelay" format, encouraging individual athletes, "trail buddies," or "trail family" teams to tackle the relentless ups and downs of the course at their own pace. Organized by a US military veteran-owned business, the event transcends a traditional race, focusing instead on personal transformation through shared suffering and resilience, fostering a powerful sense of community among participants. Reviews consistently highlight the strong support system and tribe-like atmosphere, with runners describing the experience as uniquely positive and profoundly challenging, pushing both physical and mental limits.
The rugged, entirely self-powered course demands day and night trekking, offering a raw and intense immersion in the stunning natural beauty of the area. A comprehensive "Base Support Station" at Mohawk Mountain provides essential amenities, including shade, a fire pit, hydration, snacks, and "tribe support," ensuring runners have access to vital resources on each lap. Tenting is also provided on the mountain, allowing participants and their support crews to manage rest and recovery directly off the trail. Expect an event that is "much harder than we thought," yet leaves finishers feeling "invincible, but humbled and full of gratitude."
