We could not promote the series and host each event without support. Since the series is independent with 4 event directors means you may or may not see each of these brands at each event. Overall though they make the Champion Jerseys happen and add the necessary stoke and support to keep XC growing and sustainable moving forward! With over 2500 racers over 7 events we hope you will consider them for your next cycling related purchase.

Categories 2020

Categories are listed below and offer a wide array of ways to participant in any of the series races. To be more inclusive for all ages and abilities, we have added Cat 3 (Novice) 60+ for 2020, and Cat 1 Junior Men and Women.

Each event may offer a unique age group inside of any Series category as long as it is clearly identified as a non-Series category. These categories

Series Champions in each of 31 categories will have a chance to win this jersey post-event from Pactimo if you race the 5 races required.

Champion Jersey 2020


Please know that the Categories for mountain biking do not extend to Cat 4 or Cat 5 currently. Road, CX (Cross) and other diciplines do. Ability groups at best should be used sparingly to keep the camaraderie of a good day of racing and to avoid the nitpicking that can happen when abilities are present. Elite = Pro or highest ability, Cat 1 = Expert and advanced endurance and skills. Cat 2 = Intermediate or Sport. Racers at this level enjoy the longest course with the Cat 1's, but have more opportunity to race against your peer group. Cat 3 = Novice or new to mountain biking. We won't fault someone starting out as a Cat 3, as long as your not a Cat 1/2 Road Cyclist and or Cat 1 CX Rider.

The spirt of MTB is steeped in the ability to take care of yourself and be self-sufficient. Our task as race directors is to provide an inclusive and safe environment for all to participate and have fun while maintaining competitive fairness. We are part of the Oregon Bicycle Racing Association Rules that include licensing and insurance for the production of the Oregon XC Series.

Any rider may self-select any category except Elite Men or Women and Junior Cat 2 or Junior Cat 1. Please request an upgrade to membership@obra.org or for juniors please look OBRA Junior Racing page on this site to submit the google form.

This Junior form is looked at for overall dominance and experience to allow OBRA to upgrade from Cat 3 to Cat 2 and Cat 2 to Cat 1.

All Cat 2 Juniors will stage with the Cat 2 19-39 Men or 19-39 Women and Cat 1 Junior Men will stage with the Elite/Cat 1 wave. Please make sure to stage in the 3rd or 4th row as a Cat 1 or Cat 2 of your particular field if at all possible.

Mandatory upgrades will occur through Race #3 per OBRA rules of 5 top 3 finishes in full fields in 12 months, so if you are fast, you may want to upgrade before being asked to.

If you did win your category the previous year, please upgrade to the next ability unless you do not meet the OBRA guidelines. In that case feel free to repeat your attempt at the XC Series.

If you need to downgrade, please e-mail membership@obra.org Please do not upgrade outside of the XC series for any reason and expect to downgrade from race to race. The cash purse at any event is combined overall Elite/Cat 1 and equal pay for men and women.

Each race will issue a custom plate at each event to know who you are on course. You will not use OBRA numbers for Mountain bike events.

There are a lot of Categories?

Mountain bike categories in Oregon are self-selected besides Elite, which requires an upgrade or prior USAC Pro License. You can request this upgrade to our local association OBRA but to the ELITE category. If you want a Pro license, you can race at a USAC State or Regional race outside of Oregon and go for it! We love seeing riders succeed!

Faster adult racers should move up or start at Cat 2 (Sport) or Cat 1 (Expert) to prevent sandbagging and allow more space in the Cat 3 novice and Cat 2 sport fields.

This means go ahead and enter Cat 3 Novice and go for the glory, but if you ride a lot, Cat 2 Sport is the best option to start out!

Please remember that if you are 50+ Men or 40+ Women, you do not have to upgrade beyond Cat 2 (Sport) as we do not have any 50+ Cat 1 (expert) categories as we top out at 45+ or age-graded Cat 1 (Expert) women's groups. We have tried this and had low participation in the past.

Juniors should begin by racing their age class and ability of Cat 3 (Novice); they can 'race up' but it's best if they remain in their age category and Cat 3 before moving to Cat 2 Junior and a minimum age of 14. The series site includes an upgrade form to move up faster than the OBRA upgrade if you feel you can handle longer 20+ mile routes. Also for 2020 we have added Cat 1 Junior for Men and Women to accommodate the USA Cycling and OBRA reciprocity. Post event OBRA will send Junior MTB results to USAC for better staging at Nationals. We really want juniors to succeed!

Special groups like Singlespeed, Clydesdale (200+ lbs)

Masters have many options, and for most, the Cat 2 (Sport) is where most end up if you self-identify as a person who typically does not "Race." Older riders over 60 like any rider can start out in the Cat 3 60+ and move up per the upgrade rules or self-select at any time to Cat 2 or even Cat 1 45+.


What Category am I?

If it's your first race and you want to take it one step at a time, you're in the "Novice" division or "Category 3" (Cat 3). These races take most people about an hour and are accessible to all abilities. Once you move up, you cannot downgrade unless you send a written request.

If you've done several races or come in from racing in other sports or are a fit person, you can choose to race "Sport" (Cat 2). Equivalent categories may be Cyclocross B or Faster C Riders, or Road Category 4. These races vary from 1 to 3 hours (average 2 hours) and may include technical features and sustained climbs.

If you can ride anything and can go fast for over two hours, then try the Cat 1 (Expert) field. If you race cyclocross A or place in the Top of the B field or road 1/2/3, then this may be your category or likely is.

If you are the previous years Champion in Cat 3 (Novice or Cat 2 (Sport) and under 49, please move to the next ability level for the subsequent season. If you have not met the OBRA upgrade policy you may stay in place.

OBRA Rules mandate 3 top 3's in 15 person men and 10 person women's fields in 12 months to upgrade from Cat 3 (Novice) too Cat 2 (Sport) and Sport to Cat 1 (Expert). Anyone 50 and over (Racing age as of 12/31/current year) does not have to upgrade to Cat 1 or Elite, and 50+ riders can stay in Cat 2 (Sport) per OBRA rules.

This also applies to Cat 2 (Sport) 40+ Women. This allows for the competition to stay high and field sizes to be at twenty or so per event.


60% of all racers are Cat 2 (Sport), and having fun on your bike is the name of the game. One other constant is there will always be that fast guy or fast girl, especially from other states or sports that will beat you or try to.

From Lycra to Baggie Shorts to Jeans and a t-shirt….just remember to have a good helmet and good shoes and warm clothes when necessary.

2020 Oregon XC Series Categories

Please note all USA Cycling Juniors will have their USAC numbers tracked and scored for rankings in 2020. What this means is to please let us know your USAC number when registering and if you are a Cat 1 Junior MTB we will report those results to OBRA if you are currently racing up with the Cat 1 Men 19-44 Men or Cat 1 Women. More details coming

19 more extended course categories and 12 shorter loop categories.

At select events, a third longer course may be present that is 35 miles or less for the Elite, Cat 1's, and Singlespeed's to race on. In some cases the Junior Cat 1's may be racing on the Cat 2 course staging with the Cat 2's and split out for awards. Although this is rare, it may happen and be denoted on each series events webpage.

Please, if you did win your category in novice the previous year, you need to upgrade or self-select Cat 2 Sport or Cat 1 Expert.

The Cat 1 or 2 Junior category 14-18 is not self-selected. This is because the courses are much longer and more remote. Also If you can't fix your own flat you cant move up! This is for independent, faster kids who can be accountable for the course and race with the adults!

All riders must request your upgrade from Mike Ripley mike@mudslingerevents.com or jfeatheringill@obra.org

A race resume with at least 3 top 3's from the previous year or previous year champion will be allowed to race in the Category 2 Junior category. The Oregon Xc Series does not want to limit your options but only guide you to the best experience possible. NICA racing counts as does USA Cycling, so if you're going to go big in the spring and summer before NICA, please e-mail me.

Please do not race in different ability levels from race to race. If you start out and are over your head, you can downgrade officially through OBRA and move to your appropriate ability.

Participants can select any of the above skills through Cat 1 (Expert) without an official Upgrade from OBRA. Annual licenses are recommended and only $40.00 for adults and $10.00 for Juniors. You can purchase it HERE. One day licenses are available through registration or on site that each event collects and passes on to OBRA. These fee's are 5.00 for adults and 2.00 for junior riders 10-18. Racing age 12/31 current year!

A typical time or distance of each and definition

Elite. Super Fast requires an upgrade Time to win 1:45-2hrs + depending on Distance versus Elevation

Cat 1 (Expert)

Fast and the longest course! This group stages with the Elites, People race this for either the distance or because they are fast or like the longer courses.

Cat 2 (Sport)

Time to win 1.5 hrs to 2.25 hrs depending on if this group races a lesser distance than the Elite/Expert (Cat 1) distance.

May race as the longest course at some venues but not quite ready to step up to the fastest group (Largest fields by far)

Most age groups are offered by the Oregon XC Series in this intermediate field.

Clydedales 200+ race this distance!

This group at most events will have multiple waves starts to provide the best racing with Cat 2 (Sport) men 40-49 being the largest field.

The top 3 in this Cat 2 (Sport) category would place top 10 in Cat 1 (Expert) for the Men in some cases so don't underestimate your potential.

Cat 3 (Novice) Just starting out?

I like to race 1 hr to 1.5 hrs and am out for fun and the challenge of this sport. Not quite as much commitment, but equally rewarding.


You must participate in a minimum of 5 races to score for the overall in each of the 29 categories. We added Cat 3 Men and Women 60+ for 2020 and Singlespeed Women

The OBRA Junior MTB Series will be the same events and with series leader jerseys at each event and final special awards handed out at the Alsea Falls XC

Please check your Team Spellings and data before each race if a pre registered riders list is available for each event.

Make sure to register you check both your race result and also series result by Wednesday of each week and as necessary e-mail results@creativetiming.com for questions.

Best 5 races count for individual

Toss out low series scores to leave the best 5 results

Lowest points win the series points from individual scoring

1,2,3,4,5,6,7,8,9,10 etc for all categories

Points will not carry up to the next ability level. If you upgrade or are forced to upgrade before Chainbreaker, your points will stay in that category. You must upgrade from the previous year if you have won the previous year's championship except for riders not meeting the OBRA upgrade rule.

All riders with 5 results or more will be tracked for the series final placings with riders finishing. 5 points would win the series with the last series race deciding any ties. All Champions will receive not only a Champion Jersey, but 50% off the OBRA XC/ST Championships.


5 top 3's in 12 months in a full field (10 for women and 15 for men). You can finish the series in your current category if you do not meet the OBRA upgrade policy by Race #4, but need to upgrade the next year unless you are in Cat 2 Sport 50 or older for Men or Cat 2 40 or older for women where you can stay in place and race against your peers.

Remember, no mandatory upgrades past Cat 2 for Men 50+ or Women 40+ at any point for mountain biking unless you choose to move to Cat 1 for the season.

All Champions for the Oregon XC Series and OBRA Junior Series must have raced at least 5 times, including Juniors in the Oregon XC Series presented by Rivercity Bicycles to receive Champion jerseys provided by Pactimo.


Please wear a helmet at all times while on your bike. This includes before and after Events. You can be DQ'd for not doing this. OBRA rules apply!

Please use toilets and do not urinate where others can see.

Please sanitize your hands and limit unnecessary contact with others, especially older adults with the 2020 outbreak of COVID-19. The best policy is to skip the event if you have the Flu or any other condition that would put yourself or others at risk. The recent outbreak reinforces good hygiene each and every year whether or not something new pops up.

No bad language or attitude

Pay attention at all road and trail crossings as in all cases, the course is open to other users and traffic on forest roads. 99.9 PERCENT OF THE TIME COURSES ARE OPEN TO OTHER RECREATION SO PAY ATTENTION!

Always wear your helmet at all times when on your bike, before during and after the race

Do not drop gel packs or anything on the course except for your sweat.

Please pull over if vehicles are on the roads when warming up and remember that any course could have a car on it, so pay attention.

If arriving early to an event, please use proper safety gear, including lights and bright reflective clothing, as you see fit.

There is no insurance provided by OBRA if you crash. We will call the EMT or 911 in an emergency. PLEASE REMEMBER IT CAN AND WILL TAKE AT LEAST 30 MINUTES IN MOST CASES AND OVER 2 HRS DEPENDING ON THE SITUATION. RIDE WITHIN YOUR LIMITS

BE nice when passing slower riders. A common statement is "coming by," "track left," "Can I get by?" The rule is if a rider in your same ability and age group is ahead of you and in the same specific category, the rider in front owns the track. Now, if your sucking big time on the trail, do the right thing and pull over. I can't make ya, but you will surely catch them on the next climb.
