OBRA Junior MTB Racing Series

Racing: It’s Easy to Get Started! 

By default, the regular Juniors age 10 – 18 are run on the shorter beginner-friendly course at each event. This encourages juniors to try mountain bike racing and most riders finish between 60 – 90 minutes. New junior racers are encouraged to try a local race in their area and introduce themselves to the other riders at the start line. Get connected, get involved and have fun racing bikes!
The Oregon XC Series has 7 events with junior categories; within that, we have identified all races as part  “OBRA Junior Mountain Bike Series” to make it easy for teams, parents and riders to select the best events for their young racers.
The best 5 events will count in the OBRA Junior MTB Series with custom leader jerseys and medals given out at the series finals.

6. Junior Cat 2 Upgrade Request

By default, juniors should race on the short course in their appropriate junior age category because mountain biking can be very challenging for young riders and we want to ensure that their race experience is enjoyable.

Junior riders cannot “race up” into an older junior age-group, but they may request an upgrade into “Junior Cat 2” once they have met these requirements:

Please note that on occasion OBRA reserves the right to award a Cat 1 (Expert) 19-44 Men or Cat 1 Women Open upgrade to a select few 16 or 17-year-olds that have achieved in both efforts and DNA the all out horsepower and skills needed for this upgrade.

  • Age 14 – 18 by the end of the current year and:

  • Previous XC or Junior Mountain Bike Series Winner or

  • Three podiums in mountain bike races within previous 12 months.

  • Must consent to racing with adults on challenging courses with long distances and race times of over 2 hours.

Some very exceptional juniors may race Elite once they have received their USAC Cat 1 license and or once they have dominated the  Cat 1’s at OBRA can race up with the 19-44 year old men or Cat 1 Women open for OBRA.

We are not holding riders back from upgrading as needed, but we want to ensure riders progress through the appropriate category levels for their safety on course.

If you have met these requirements, please fill out this form at least 1 week prior to your event:

Faster, experienced juniors who desire a bigger challenge on a longer course can apply for an upgrade into the “Cat 2 14-18” category.

These Junior Cat 2 waves will usually be run in with the adult sport categories or Cat 2 19-39 men or women.Check staging for each event for confirmation. Race times will vary and may be over 2 hours at some events so this is for advanced and prepared riders only. See the form below or click here to request your upgrade.
