This trail race on St. John features beautiful views, diverse ecosystems, and challenging single track climbs and descents. The course from Cruz Bay to Coral Bay follows a renowned series of National Park trails that traverse peaks, ridges, ravines, and beaches across the entire island. The total distance is 13.6 miles with an elevation gain of 2,772 feet. The course is technically challenging with several steep ascents and descents on very rugged trails. The finish line and post-race celebration and awards ceremony will be at Skinny Legs in Coral Bay.
Runners will be largely self-supported, carrying at least one water bottle. There are several transition checkpoints across roads that will have replacement water and supporters can also wait there to cheer runners along. The longest segment between checkpoints is 4.5 miles (Fish + Reef Bay). There are several public toilets along the route, including at miles 0, 2.5, 7, 9, and 11. The maximum time for this race will be 4.0 hours. As a guide to estimating your time, assume it will take 2.5 times as long as the 8 Tuff Miles road race. With that in mind, we suggest that you should have less than a 1 hour and 35 minute recent finish or equivalent. This cutoff is intended to avoid taxing our volunteers or St. John Rescue in their sweep of the course. We will also set a mid-race cutoff at the top of the Reef Bay trail (mile 9).
Before registering please review the course description and make sure this race is a good match for your abilities and training goals.

- If you don’t have any trail running experience, this race is not for you.
- If you have never run a trail race or half marathon before, this race is not for you.
- If your 8 Tuff Miles time is greater than 1 hour and 35 minutes, this will probably put you over the 4.0 hour time limit so this race is not for you.
