Chainbreaker Race Series

Established 1996

All abilities welcome from beginners to professionals, juniors to masters!

While the Two Bulls fire impacted the area in 2014, the conditions are improving every year and damaged trails are being restored every spring. Riders take several trips through the stadium area to make spectating and cheering fun for families, along with free kids races, food and drinks available on site.

The cross-country race is the part of the Oregon Off Road Series which encourages racers from across Oregon to travel to select races over the duration of the season.

These events are fundraisers for the Bend Endurance Academy.

Course Preview Pre-Ride


  • Open to the public and all BEA Junior Riders and families
  • Meet at BEA office to car-pool by 9:00AM
  • Or rendezvous at the Start Line at 9:30AM if you know where it is
  • We will provide a few volunteer ride leaders that you can follow around the course, or explore on your own, but you must be capable of riding on your own at this event! We offer no guarantee of support.
  • Plan on riding between 2 – 2.5 hours.
  • Course will be provisionally marked by the end of the day Friday — this is an open forest with lots of users so we cannot guarantee the markers will remain up at all times. BRING A COURSE MAP / GPS.

Although the course will be provisionally marked, we highly suggest you use the maps and GPS files — we will post them with the new maps in April.
