Enduro is a form of Mountain bike racing in which there is a greater proportion of downhill sections, which are timed, to uphill and cross country sections. This aims to test rider’s technical bike handling skills as well as providing endurance and climbing. Enduro’s ‘All Mountain’ discipline therefore favours riders with a breadth of skill, on multi discipline cycles; lightweight XC bikes may lack sufficient suspension travel for fast downhill control, whilst full DH bikes may not allow a rider to climb the uphill sections.

Official Race Rules

We at the Oregon Enduro Series like to make things as rider friendly as possible. We limit our “Official Rules” to the basics. We want to make sure everyone is as safe as possible and participants are participating on an equal playing field.

Number Plate

Number plates must be placed on handlebars. DO NOT BEND, CUT, TRIM, ALTER SHAPE OR TAMPER WITH NUMBER PLATES IN ANY WAY!! Alteration of number plates may cause misreads by the officials. If we find that you have altered your number plate, or if you damage or lose your number plate there may be a $10 fee for replacement.

Foot Down At The Start Line

Racers must have one foot on the ground at the start line until the starting buzzer sounds; There will be a five second penalty applied to riders who lift both feet off of the ground within less than three seconds of the final buzzer. There will be a one minute penalty applied to riders who lift both feet off of the ground more than three seconds before the final buzzer.


Refreshment stations will be located throughout the transition stages as well as the Expo area with cups. HOWEVER, we ask that you use your camelback whenever possible to reduce waste and come prepared with your own hydration just as you would going out for a ride.

Transition Stages

We request that you move through transition stages promptly so as not to hold up other category racers.


Flat tires and/or “mechanicals” are a part of Enduro racing, and therefore no one is allowed to re-start a stage.

Protective Gear

A good working helmet is required. Full face helmets and knee pads are mandatory for selected courses. Please check website for individual event requirements.


You may only race one bike per event. Your frame sticker must be placed on your bike frame, and be visible to race officials.

No Headphones

Racers are not allowed to wear headphones at the starting lines, or during any part of the race for the safety of the rider and others.
