This is a 152-mile ultra trail marathon relay starting at midnight on October 1st at Mohawk Mountain Ski Area in Cornwall, Connecticut. The Iron Hike Fall Olympus Mons Ultra combines running, hiking, and walking over an 84-hour window with 72,590 feet of elevation gain. As a relay format, teams rotate through the course, making it accessible for athletes who want to tackle an ultra-distance event without running the entire distance solo.

Given the substantial elevation and extended time limit, participants should prepare for mixed terrain and variable conditions across the autumn mountain environment. This relay structure allows endurance athletes to compete at their own intensity while contributing to a team effort across the demanding mileage and vertical.
