About us
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!"

🚴 Wed 3/11 5:20 pm | FUN RIDE SANTIAGO OAKS stay hydrated ride
Santiago Hills park, 8233 EAST WHITE OAK RIDGE, ORANGE, CA, USbring water, stay hydrated
Roll 5:25pm // Distance 8+ miles // Elevation 900+ feet depending on weatherroute: .. subject to change based on weather and unforseen circumstances
Let's take advantage of Daylight Savings for a super fun mid-week ride at Santiago Oaks.
Lying peacefully in east Orange alongside Santiago Creek, the 1,269-acre Santiago Oaks Regional Park is a nature lover's paradise. This secluded refuge offers hikers, bikers, and equestrians the natural charm of mountain vistas, an orange grove, a meandering creek, and a mature forest of many different species of trees. Wildlife abounds, and a series of interconnecting trails leads through shady groves and to a lookout featuring an awe-inspiring view of Orange and the surrounding foothills.
There is a little bit of everything for the outdoor enthusiast, with quite a few trails in a small area. Think mini-enduro park. You'll get a solid workout on the climbs and big smiles on the descents.BLUE LEVEL RIDE

🚴 WED 04/01 - SUN 04/05 | SEDONA BABY! | ADVANCED BLUE & UP 🚴
Sedona, AZ, USNOTE: E-bikes are technically not allowed on any singletrack in the Red Rock District of the Coconino National Forest. Ride at your own risk.
Join us for an unforgettable multi-day mountain biking getaway in the red rock paradise of Sedona, Arizona! This trip is all about epic singletrack, stunning desert scenery, good vibes, and riding some of the most iconic trails in the Southwest.
Sedona offers a perfect mix of flowy trails, technical rock features, punchy climbs, and rewarding descents. All set against jaw-dropping red rock formations. We’ll ride a variety of classic Sedona routes, tailored to the group’s ability and energy level, with plenty of time to regroup, session features, and soak in the views.
RIDE DETAILS
Intermediate to advanced riders recommended. You should be comfortable riding rocky terrain, ledges, and sustained climbs. This is not a beginner trip, but we’ll keep things supportive and fun.WEDNESDAY AFTERNOON
Adobe Jack Trails & Bike Skills Park
Distance 7 miles // Elevation 1,000 feet // Blue LevelThe Adobe Jack trails in Central Sedona are a great warm up to Sedona riding and a favorite "chill" ride for locals ranging in difficulty between blue and light black. We will start by climbing Adobe Jack to check out Devil's Kitchen Sinkhole at Soldier's Pass then climb up to Ant Hill for stunning 360 degree views of Central and West Sedona. This route does a double loop so you can descend the two best trails in the system: Grand Central and Javelina.
THURSDAY
Ride Option #1: Dry Creek Trails
Distance 15+ miles // Elevation 1,500+ feet // Advanced BlueThe Dry Creek trails in West Sedona are a great introduction to riding in Sedona. The area is more XC-oriented and less technical (at least for Sedona) than the other major trail systems (sans the Adobe Jack trails). This is my favorite intermediate ride in Sedona combining Chuck Wagon, Mescal, Canyon of Fools, Aerie, etc. to create an epic ride with stellar views and several different types of terrain. The area is also home to Devil’s Bridge, the most popular hike in Sedona, so make sure to get an early start because parking is a pain.
FRIDAY
Ride Option #1: Village of Oak Creek Trails
Distance 15+ miles // Elevation 1,500+ feet // Advanced BlueThings get a little more kicked up in the Village of Oak Creek. This is probably the most popular intermediate trail system in Sedona. We will start on Slim Shady, then Templeton to Cathedral Rock, down to Easy Breezy and depending on how everybody is feeling we will loop under the road to do the Hog Trails and Broken Arrow or do Little Horse to Llama.
