About the Rabbit Run 5k & OC Challenge Wild Hare 5k & Half Marathon
The course runs out and back along a landscaped trail shared with cyclists, dog walkers, and other runners. The surroundings are planted and kept up, and the path feels more park-like than urban. The whole event has an Easter theme woven through it, with eggs to find along the route and a chance to take photos with someone dressed as the Easter Bunny at the finish.
All packet pickup happens on race morning at Jeffrey Trail Middle School, with registration opening well before the first wave. The school also serves as the parking lot. Restrooms are inside the school buildings on both sides of the expo area, and signs point the way.

The Rabbit Run 5k & OC Challenge Wild Hare 5k & Half Marathon has been held every year since at least 2018. That is as far back as RunSignup's records for this race go, so it may well be older.
How we calculate these stats: RunSesh calculates these figures from the most recent published results of past editions, sourced from RunSignup. We show aggregates only: field size, winning and median times, and the cutoff. We never publish individual finisher tables. Last updated Oct 22, 2026.
