All-Mountain World Championships

Two-Day Mountain Bike Stage Race, featuring:
Point to Point Cross Country Race and Downieville Downhill Race

Bike companies spend thousands of dollars and countless hours engineering office bound gizmos to mimic the most extreme trail conditions. Here in Downieville, we have the All-Mountain Class, which not only tortures the bikes, the riders get to learn what they’re made of too.

Racers compete in both the Point to Point Cross Country and the Downieville Downhill, on the SAME bike. Riders must choose their weapons wisely; a bike that climbs efficiently, descends with precision, and can handle a high-speed beat down for 42 miles on the way to victory.

There will be a mandatory bike weigh-in and a parts check prior to the XC Race, either at registration Friday in Downieville (3-7PM) or Saturday in Sierra City (6-8AM). No switching of parts, or modifying of parts. The bike must weigh the same each day, or the racer is bumped from the All-Mountain class. All Mountain racers must also weigh in 30 minutes before their Downhill start time on Sunday at the Start on Packer Saddle.

Pro All-Mountain category- there will be a timed cut-off for reaching Downieville in the Cross Country race. Riders have 3 hours to complete the 26.5 mile course, or they are pulled from the All-Mountain category.

In the spirit of competition, we'll be using a Points System to determine our All-Mountain World Champions. Lowest total wins. A points tie will default to the riders DH finish position.

"Stick to the Track"
Some riders seem to be all too familiar with racing events like Megavalanche, and other big mountain enduros, where the fastest man or woman down the mountain, regardless of the route, is crowned champion. This type of racing became a problem in the 2010 Downieville Classic, as we had several riders using what we like to refer to as "Hillbilly Lines". We are officially ending this method of racing, by placing course marshals in known “cutter” areas. Riders that do not stick to the track will be disqualified.
