Flagstaff to Grand Canyon Stagecoach Line Races
The event is a multi-discipline endurance weekend presented by Babbitt Ranches and scheduled for September 19–20, 2026. It uses sections of the Arizona Trail north of the San Francisco Peaks, including course mile 19. Registration for the event is open and closes on Monday, September 14 at midnight.
Distances and event types include:
- 100-Mile Run
- 55K Run
- 100-Mile Mountain Bike Race
- Relays for run and bike events
There are separate race manuals and course information documents for the run and the bike events. Past race results and photo galleries are maintained for reference. The event also documents production of the finisher buckles for the 100-mile run and the 100-mile bike race.
A linked opportunity called the Under the Shadow of the Peaks Endurance Double pairs this event with the Flagstaff Marathon. To qualify for that double award, a participant must first finish either the 100-mile solo run or the 55K solo run on September 19–20, then return on October 3 to complete the 26.2-mile Flagstaff Marathon; the double carries a special finisher award.
All descriptions above reflect published event materials for the 2026 Stagecoach Line races. Visit the organization's website for the most recent information.
