A unique “25 Hour” endurance event challenges riders, solo or in various team formats, to complete as many laps as possible on a 13-mile loop within 25 hours. The event is produced by premier regional operator Gro Races and is rated by Strambecco as one of the best MTB events in the Southwest. 25 Hours in Frog Hollow is also part of the N24 Series, an emerging 24-Hour MTB race series produced in collaboration with GroRaces, Zia Rides, and Mudslinger Events.
The course for the race takes riders through a mix of rocky terrain, technical descents, and some smooth singletrack. The Frog Hollow region of southwestern Utah lies in the shadow of Gooseberry Mesa and Zion National Park just outside Hurricane, Utah. The region is known for its unique geology, which includes colorful sandstone formations and towering mesas. The course takes riders through various environments, from sagebrush flats to high desert forests. The terrain is rocky and technical in many places, with steep climbs and descents that test even the most skilled riders.
The event attracts riders from around the world, with many participants camping at the race site for the duration of the event. There are different categories of riders, including solo riders, teams of two, four, six, and eight, and even corporate teams. The goal of the race is to complete as many laps as possible within the 25-hour time limit, with the team or rider that completes the most laps being declared the winner.
In addition to Frog Hollow, the N24 Series includes 24 Hours in the Enchanted Forest and Oregon 24/12.
