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.

  • Kid’s Races
  • Big Expo of Sponsors and Exhibitors
  • Easily accessible from Riverside, San Diego, and Orange County after work.
  • Dinner Available for purchase
  • Docent Brewing Beer Garden

Trailwork Kickoff Party tomorrow AM for last minute “rallyers”

Saturday, June 19 – 9am to 2pm

Location: Lakeview Park, 5305 E Santiago Canyon Rd, Orange, CA 92869

Come help make this year’s trail connections and prep the course for the best season ever. We need all hands on deck as this will be the most creative course since 2015 when the lake was empty and the fire burned the hill climb.


Gloves water, and hand tools if you got ’em (shovel, rake, McLeod, etc.)

It doesn’t have to be racey to be fun. Hope you’re enjoying the flow of your weekend. #happytrails …. 5 weeks left till we’re all together for your favorite bike party. ...

And so the story begins. Don’t miss your chance tomorrow at 8pm the moment we have been waiting for. 100 season passes have already been sold back in 2020 and some 1 race entries rolled over. That leaves us with only 400 Main Event races to sell each week and tomorrow we’re only selling race #1: July 20. #raceoth #mazdaoth ...

Happy 58 days till OTH 2021. The @linkedcycling guys and gals have been the glue holds the whole kids race together (even back to when there was water in Irvine lake) 📸 @gielishtroy
we’re so thankful for these peeps and their service to our community #thereason #mazdaoth

Trailwork days are coming! Supported by your volunteer effort and @kawasakiusa #kawasakimule support.
