Race Location

THE “OTH” MAGIC CONTINUES- This is the RACE FOR EVERYONE; what began in 2009 was MAGIC. We have live, breathe and love the race day magic of Over the Hump at Irvine Lake, and we continue to be passionate about serving the Orange, Riverside, Los Angeles and San Diego racers that are family, with a central race location.
What began as a dream to provide a to connecting experience for the mountainbike community continues to galvanize YOUR people. If you haven’t been here ever or in a while we doubt you’ll be able to stay away after you come this year.
