How IronHike works at Mohawk Mountain
Every event uses the same lap: 1.25 miles up and down a Mohawk Mountain ski trail, with 595 feet of gain and loss.1 The organizer lists the summit at 1,600 feet and the base at 920 feet.1
The ski area's own figures differ slightly. Its statistics page gives a base elevation of 960 feet and a vertical drop of 650 feet, with the same 1,600-foot summit, and names Deer Run as its longest trail at 1.25 miles.3 The lap numbers above are the organizer's.
Each event sets a number of laps to finish inside a time window. The event ends when you decide it ends or when the final bell rings.1 There is no podium, no records and no age-group awards.1
The seven events
The events share the same lap and differ in the time window and the number of laps.1
- Kuwohi: 12 hours, 12 laps, 15 miles, 7,140 feet.1
- Double Kuwohi: 24 hours, 23 laps, 28.75 miles, 13,685 feet.1
- Answer the Bell, Basic: 24 hours, 24 laps, 30 miles, 14,280 feet.1
- Denali: 48 hours, 35 laps, 43.75 miles, 20,825 feet.1
- Everest: 72 hours, 49 laps, 61.25 miles, 29,155 feet.1
- Answer the Bell, Full: 84 hours, 84 laps, 105 miles, 49,980 feet.1
- Olympus Mons Ultra: 84 hours, 122 laps, 152.5 miles, 72,590 feet.1
Which event suits a first-timer
Kuwohi is the entry point.1 The organizer's rule of thumb is that if you can hike for four hours or finish a 5K, you are ready for it.1
At the other end, the organizer describes the Olympus Mons Ultra as recognized among the top four hardest ultra events in the world and says few people have ever finished it.1
The organizer reports that hundreds of people have taken part since 2023, from 30 states and 3 countries, aged from 10 into their 70s.1
Solo, Trail Buddy and Trail Family
The FlexRelay format lets people take part solo, as a Trail Buddy pair, or as a Trail Family.1 The organizer's description calls a Trail Family a team of four, while the registration options list it as a team of 3 or 4.1
Team members have no minimum or maximum laps, mileage, elevation or time on the course, so the team decides who is climbing and when.1 You can register without a partner and add one later at no charge.1
Answer the Bell follows the backyard ultra format, with a lap on the hour, every hour.1 The Basic version is solo only.1
2027 schedule
The spring series runs from Wednesday check-in through Sunday, June 2 to 6, 2027.1 The fall series runs October 6 to 10, 2027.2 The pattern is the same in both: longer events start earlier in the week, and every event apart from Kuwohi ends at the final bell at noon on Sunday.
- Olympus Mons Ultra and Answer the Bell Full: check-in Wednesday evening, start at 12:00 a.m. Thursday (June 3 or October 7).12
- Everest: starts Thursday at noon (June 3 or October 7).12
- Denali: starts Friday at noon (June 4 or October 8).12
- Double Kuwohi, Answer the Bell Basic and Kuwohi: start Saturday at noon (June 5 or October 9). Kuwohi ends at midnight that night.12

Listed drive times are 1 hour from Hartford, 1 hour 16 minutes from Springfield, 2 hours 20 minutes from New York City and 2 hours 35 minutes from Boston.1
