Terrain Race | Irvine 2026

Terrain Race Irvine is a mud-and-obstacle 5K at Oak Canyon Park, starting in Silverado, California. The race is scheduled for November and covers about 3 miles. It is short in distance but built around getting dirty, climbing, crawling, and hanging on. The course includes mud pits, walls, ropes, monkey bars, and more than 11 other obstacles shaped around the park terrain. It suits runners who want a playful obstacle course more than a standard road race, and the event also has a festival area with vendors after the run.
