Trail Challenge - The Dublin 26 2026

The race.

The Dublin 26 is a challenge event running from September 7 through October 11, 2026, in Dublin, CA. Participants choose between two options: complete 26 miles of walking, hiking, or running, or complete 65 miles of biking. Miles can be accumulated all at once or spread across multiple days and must be tracked using the RaceJoy application. For the running/hiking/walking challenge, miles may be completed on recommended trails, neighborhood parks, or participant-selected routes within Dublin. Biking participants should start in Dublin but may extend into surrounding cities. All registered participants who record their miles by the October 11 deadline receive a commemorative t-shirt.
