Dates & Location:
Monday Nights - June 3, 10, 17, 24 & July 8, 15, 22 & 29 on the infield of Portland International Raceway.
As usual, we will take a mid-series break (NO short track on Monday July 1st!), but we hope you will join us on Sunday June 30 at the Skibowl Mt Resort where we will host the Six Hours of Mt Hood.

Race Format & Course Description:
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 1.0 mile and racers will do multiple laps for the duration of their race (see schedule below). Everyone finishes on the same lap as the race leader in their race heat, regardless of whether you get lapped.

The course is pretty flat and doesn't feature any major climbing (elevation gain per lap is only 20 to 40 ft), so you don't need a lightweight bike to rock this race. Indeed, folks are racing on all types of mountain bikes, cyclocross bikes and gravel bikes at Short Track!

Race Categories:
Elite Men, Elite/Cat 1 Women, Cat 1 Men U45, Cat 1 Men 45+, Cat 2 Men U40, Cat 2 Men 40-49, Cat 2 Men 50-59, Cat 2 Men 60+, Cat 2 Women U45, Cat 2 Women 45+, Singlespeed, Clydesdale (200 lbs+), Cat 3 Men 10-13, Cat 3 Men 14-18, Cat 3 Men 19-39, Cat 3 Men 40-49, Cat 3 Men 50+, Cat 3 Women 10-13, Cat 3 Women 14-18, Cat 3 Women 19+.
IMPORTANT NOTE: all age categories are based on "racing age", i.e. your age on 12/31/2018. Also, all categories are self-selecting except the Elite Men, who are subject to OBRA upgrade rules.

All races will start on time, so schedule enough time to travel to PIR.

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, so you don't interfere with the race or confuse course marshals). No pre-riding the infield/motocross track after 5:45pm!

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 50-59, Cat 2 Men 60+, 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.


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.
