Explore all of Dinosaur Valley across 15 scenic miles—Saturday or Sunday start
The 25K combines the 5-mile short loop with one full 10.5-mile main loop, covering the complete range of terrain Dinosaur Valley has to offer in a single outing. Two separate race starts—the Triassic 25K on Saturday morning and the Cretaceous 25K on Sunday morning—each carry their own awards, so runners get to choose the day that fits their schedule. Hiker-friendly cutoffs make this an accessible event for all fitness levels.
