All races will start on time, so schedule enough time to travel to PIR, get all your stuff together, ride your bike from the parking lot to the infield, and get registered.

Course Description:
All races will be held on the infield of PIR. The course - which we will change up every week - is a combination of grassy flats, twisty singletrack (under the trees), and rolling dirt track (on the motocross course). The typical lap distance is about 1.5 mile and racers will do multiple laps for the duration of their race. The elevation gain per lap is 20 to 40 ft.

The short track course and surrounding area will be open for pre-riding on race days from 4:00pm through 5:45pm, when the Cat 1 Kids are ready to start their race. If time allows, racers will also be able to pre-ride the course outside the motocross track in between race heats (but you have to stay behind the last rider, as to not interfere with the race). No pre-riding the infield/motocross track after 5:45pm!

Like last year, we will host every week two FREE short track pre-ride & skills clinics, one for Women racers and one for Junior and Novice Men racers. Click here for more details.

Race Plates:
All racers will receive a special series race plate at their first race of the season. These are the only race plates that will be honored by our officials (no OBRA MTB XC series race plates or cloth bib numbers!). If you forget or lose your race plate, you'll have to buy a replacement plate at the registration desk (cost: $5). If - anytime throughout the series - you upgrade to another category or decide to race a second race, you have to get a new plate for your new category at registration (and turn in the plate of your old category, so we can reuse it). Please make sure to attached your plate to your handlebars using 3 (THREE) pipe cleaners or zip ties (to prevent your plate from flipping over) and IN FRONT of your brake/shifter cables. If your plate is not readable, you might not get scored correctly.

Results, Series Points, Series Standings, Team Competition & Awards:
- Weekly results, series points, series standings and team standings are managed and published by OBRA. If you have questions or corrections about results, please email the OBRA person listed at the top of the results page. They will use the same series points system as last year.
- Points will be awarded 30 deep in each category.
- Best seven out of eight races count toward overall results.
- Series awards (3 deep) & final series raffle will take place at the series grand finale.
- Since we are racing for eight weeks this year, two sets of Oregon BAR (Best All-Around Rider) points can be earned (one set of BAR points for the first 4 races and another set for the last 4 races).

Upgrade Rules & Guidelines:
Racers who podiumed in last year's series in 3 or more races (or who ended top-3 overall in the series) are asked to upgrade to a higher category (except for Cat 2 Men 55+, Cat 2 Women 35-44, Cat 2 Women 45+, Singlespeed, Clydesdale, Elite Men, Elite/Cat 1 Women, and Juniors). Cat 3 (Beginner) racers who had at least one top-3 finish in last year's series are also asked to upgrade to Cat 2 (or an open category like Singlespeed or Clydesdale), so any "true beginners" and other "progressing Cat 3 racers" get a chance of placing. Further, any Cat 3 racers who are racing at a level that is deemed "head and shoulders" above the rest of their field may be asked to upgrade during the series.
Note: the upgrade rules do not apply to junior racers. Moreover, racers are free to upgrade mid-series and transfer 50% of their points for up to 3 races.

- $750 cash purse for Elite Men and Elite/Cat 1 Women (distributed to "Top 3 Overall" in each category).
- More than $2,500 worth of product and prizes.

This series is only possible thanks to the dedication and commitment of many volunteers. We are always in need of volunteers to help with course set-up, course marshaling, registration, lap counting, kids races, food station and clean-up. If you volunteer for 3 or more 30' shifts, you get to race for free (or get a free race entry for a friend). If you commit to the whole series, you get a free Series Pass. Volunteer positions are filled on a first-come first-serve basis. If you are interested in volunteering and helping us making it all happen, just contact Kris Schamp at kris@portlandracing.com.


1) Helmets are mandatory at PIR and at all OBRA-sanctioned races. Make sure to bring one and wear it any time you are on your bike, including on your way from your car to the infield and back.

2) Follow proper race etiquette. Be courteous to other riders on the course, especially when passing/lapping slower riders. Make slower riders aware of your intent to pass in a friendly, non-intimidating manner. Be patient and wait until there is enough room to pass. Whe passing, leave plenty of room and don't cut off riders. Be extra careful around junior riders.

3) Race defensively and within your limits. This is not the world championship of Monday night short track racing! In other words, it's not worth to take unnecessary risks that could result in injury. On the motorcross course, use proper pumping and weight shifting technique and avoid getting airborn. A bad landing on the hard clay sole can be unforgiving. Also race defensively around trees, fence posts, and other static obstacles. Prior to your race, pre-ride the course to familiarize yourself with technical sections and hazards along and on the course. If you don't manage to pre-ride the course, ride a bit more conservatively on the the first lap and go harder on the next lap.

4) Do not bring any beer or alcohol into PIR. There is an explicit rule (posted at the main entrance) that prohibits people (racers and spectators) to bring in alcoholic beverages into the venue. Please help us ensure that everyone abides by this rule. For all clarity: when the PIR concession stand is open, you will be able to buy beer from them (as well as other non-alcoholic drinks, ice cream, hot food and snacks).

5) No dogs please. We all like animals, but they add another element of complexity.
