A Look at OTH History



You say, “That’s cool, but I don’t race.”  You know what? Neither did 1,300 of the 1,700 people who raced this past season. But they found an experience like no other…and their families loved it too!

We can’t wait for you to join us for the Family Gathering at OTH. Kids through grandparents have the time of their lives!

So Come for the Race, Stay for the Party.

  • Easily accessible from Riverside, San Diego, and Orange County after work.
