What we’re about
We are a group of riders that enjoy and are very passionate about mountain biking and all aspects of it. We believe in riding within a group for camaraderie, fun, knowledge and most importantly safety while out on the trails. Everyone that starts a ride with us will finish. Struggling or been off the bike for a while? No Worries!! The group who shows up to ride will always determine the pace. We will make sure everyone that shows up to ride has a fun and enjoyable time. We want to help you get better, faster and stronger! You get out of mountain biking as much or as little as you put into it!!
Many of our rides take place on the beautiful trails that Orange County has to offer. Additionally we are now starting to expand and offer rides in LA area, the Inland Empire and all the way down to San Diego County. Some of our favorite spots to ride are Fullerton Loop, Santiago Oaks, Whiting Ranch, Aliso and Woods Canyon and El Moro (Crystal Cove), Sycamore Canyon, Box Springs, Skyline, Chino Hills State Park, Big Bear and so on. In addition to this we occasionally will plan weekend getaways, as well as hit up trails that other places in So Cal and beyond have to offer.
So what are you waiting for? Come and judge for yourself. We encourage and welcome anyone and everyone to join us on our rides. Have ideas or want to ride somewhere? Drop us a line and we’ll make it happen.
"Sleep. Work. Eat. Ride and Repeat!"

Roll 8 AM // Distance 30 + miles // Elevation 5,500 + feet {Full Distance}
It is a Bommer Open Access Day, with so many open trails this is worth hitting. You must register, link below.
*** I posted a picture of my my full ride. It is close to 35 miles and over 5500' of climbing. Feel free to join and enjoy some or all, but keep in mind, to hit this distance/elevation there will be limited regroups and the ride will be kept moving. We need to be off the open space by 2 PM ***
We will start at Ridge Park and ride Lizard up under the 73. Ride Serrano Ridge to cattle, rabbit and fox trails. Make some decents, climb out.
Then ride Ridge Route, go up Turtle Rock Singletrack as an out and back, and climb West Fork back to the cars.You can do as much or as little as you want, it is easy to get back as I'm not sure of the mileage or distance on this, but it could be hefty.
This is a once a month opportunity so if you've ever wanted to hit this it is a great time to do so. Parking at El Moro can be tough and we will roll at 8 promptly as the open access stuff is available starting at 8. this gives us a little time to get there. Parking can be tough at El Moro too so keep that in mind.
Not sure of ebike rules, you're welcomed but knowing what and where you can ride is on you.
I posted maps of the trails for you to check out. REGISTER HERE:
