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.
