Racers in 2009, helped us create and build the never before before raced Irvine Lake Course….it was a big community undertaking.

Orange County Mountain Bikers’ own local race series!

Going into our 6th season this year, Over the Hump Mountain Bike Race Series, kicked off our inaugural season in 2009 with 2 races. Both sold out!  That lit the fire.  2010’s 12 race series saw 1,500 people racing, with 2012’s season rolling 2,500 racers through the finish line. Watch out! It could be you who catches the racing bug in 2016!

Midweek, and easily accessible after work from all over Orange County.OTH is designed to be a fun, relaxed event for everyone. Our race course has been designed to challenge all levels of riders, and give you a great place to experience the fun and excitement of mountain bike racing. Our beautiful course offers a variety of scenic terrain with views of Irvine Lake and Santa Ana Mountains. Weave through the pine trees above the lake to single track in the cottonwoods.

Come out and give racing a try, or just enjoy the buzz, as a fan club for your racer or team!  Irvine Lake’s course sends racers by the staging area 3 times every lap. Looking forward to seeing you out there with us.

What’s the rest of the Over the Hump Mountain Bike Race Story?

You’re in the middle of writing it. Everyday someone puts their leg over the bike, and heads to Castaic Lake, or Irvine Lake, trains or even visits as a part of a races “pit crew” they are writing the Over the Hump Story.

Throughout the year, we’re going to be introducing you to the people who make Over the Hump, the amazing, vibrant, and exciting community that it is.  Over the Hump is people, not a race. It’s a community, not a racer, or a team.  We have witnessed turn into a family, from the first time you rolled under the start banner, and put rubber to dirt (and asphalt).  Over the Hump, is our Tuesday night home, and we’re glad we get to share the backyard with so many amazing people.

Matt, OTH co-ounder shares his story, and an overview of where Over the Hump came from.

Now you get to help us write the story of where it’s going.

This is your Race, this is your Community, this is your Family. We’re just glad to be a part of it. Thanks for including us in the journey.
