⚡ ARIZONA E-BIKE RACING STARTED HERE. ⚡

We’re beyond excited to welcome you to another incredible year at Bear Jaw Groove — Flagstaff’s premier mountain bike event, celebrating community, adventure, and the joy of riding together!
We’ve got a category for every kind of rider — from traditional analog/geared bikes and single speeds to e-bikes, with e-bike racing being part of the Bear Jaw Groove story for years.
We’re proud of our history of supporting e-bike riders and giving them a dedicated place on the starting line, helping make e-bike racing part of Arizona’s growing mountain bike community.
Whether you’re back to chase a personal best, racing with friends, lining up on an e-bike, or bringing along the whole family, this year’s race promises something for everyone.
Get ready to tackle the 10.5-mile loop course that starts on a fire road for roughly a mile to let the pack thin out before hitting the legendary Arizona Trail (AZT) with its tight, smooth single-track flowing into Rocky Moto. These trails offer a gradual, sustained climb with fun challenges like roots and rocks before you connect to Moto! From the top, you’ll swoop into an exhilarating 3.5-mile descent — mostly smooth and fast with one or two rock gardens — before looping back through single-track to the Start/Finish. Ride it solo, with a duo, or with a team of 4.
This year at Bear Jaw Groove you can choose from a variety of events designed for riders of all styles and abilities — from competitive racers to first-timers:
🏁 6-Hour Mountain Bike Relay

It started in the 90’s. Dusty singletrack. Big lungs. Bigger personalities. A race that circled the Peaks and became the stuff of local legend. Now… the Cosmic Solstice is back. Bear Jaw Events is reviving this classic Around the Peaks experience and bringing it into a new era — reimagined as a timed benefit race that blends grit, nostalgia, and community under Flagstaff’s wide-open cosmic skies.
This year, the Cosmic Solstice is a timed benefit event supporting the Flagstaff Biking Organization, the stewards who help build, maintain, and advocate for the trails we all depend on. Every stride helps sustain the dirt beneath our feet and tires.
Whether you remember the original 90’s edition or you’re experiencing the Cosmic Solstice for the first time, this is your invitation to be part of the comeback.
Dust off your retro vibes. Bring your crew. Chase the light. The legend returns on August 15, 2026. Registration coming soon!

Previously Gaspin' in the Aspens, Bear Jaw Events has resurrected this fun race by popular demand and renamed it Groovin' in the Aspens! This is a 6K/10K/20K/30K/50K trail run through the pines of some of Flagstaff's best trail systems!
