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 bumpy dirt track (motocross course). They typical lap distance is between 1.0 and 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. 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! It's too confusing for racers, course marshals and officials.

FREE Kiddie Races (for kids age 0-9):
Each week, Islabikes will organize three free kiddie races.
- The "Under 6 Kids" will do a short, 1-minute flat mini-loop on a grassy spot under the trees, close to the start area. This race is for the very young ones. Trikes, training wheels and push-bikes are all allowed in this race, as well as helping parents, as long as they don't obstruct the racing kids.
- The "Under 8 Kids" will do a slightly longer, 3-minute loop in the same area, with possibly some more technical sections and obstacles.
- The "Under 10" Kids will do one full lap on the regular short track course, off the back of the junior field. This race is restricted to expert kids who have the ability to race a more technical course.
- All kiddie races will start at 5:30pm, prior to the Cat 3/Junior race.
- Kiddie racers race for free but parents/guardians of kiddie racers still have to sign a waiver.

- Online registration for individual races: each week, from Tuesday through Saturday 12pm (Noon), you will be able to register for the next, upcoming race.
- Series pass holders and pre-registered riders will enjoy a weekly call-up at the start of their category, in the order that we have received their registration.
- Day-of-race registration: while we prefer racers to pre-register online (and enjoy a $5 discount), racers can register at the races from 4:30pm to 15 minutes prior to their start time.
- The registration tent is located on the infield of PIR next to the motocross tower and near the start/finish.
- OBRA membership required for all racers (except kiddie racers) - single day: $5 / annual membership: $25
Important: Per OBRA rules, all riders who claim to be OBRA members will have to show proof of current membership at their first short track race of the season. Without proof of membership (i.e. membership card or confirmation email from OBRA), you will have to purchase a single-day license ($5).
- If you plan to pay at the race, please bring cash or checks. WE DO NOT ACCEPT CREDIT CARDS AT THE RACE but there is an ATM at PIR (at the main entrance, across from the pay booths).

Upgrade Rules:
Racers who podiumed in last year's series in 3 or more races (or who ended top-3 overall) will have to upgrade (except for Cat 2 Men 55+, Cat 2 Women 35-44, Cat 2 Women 45+, and Singlespeed).
Cat 3 (Beginner) racers who had at least one top-3 finish in 2011 are also asked to upgrade, so the "real" beginner get a chance of placing. 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.

Race Plates:
Like last year, all racers will receive a special series race plate. 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).

FREE SHORT TRACK SKILLS CLINICS for Women, Juniors & Novice Men:
This year, we will host three FREE weekly skills clinics. Seasoned short track racer Elaine Bothe (from the Sorella Forte team) will again be leading the Women's clinic, Ted Byram (from Bike N Hike) will be teaching the Juniors and Novice Men. The clinics will include a guided bike-through of the course, various fun skill drills, tips on "safe and defensive racing", and a ton of race tips from folks who not only know how to race hard but also how to race smart. All clinics will run from 4:30 to 5:30 pm on the race course. Meet-up is at the bleachers on the right of the registration tent. You don't have to register in advance for the clinics, but you need to fill out a series waiver.

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

Series Points & Awards:
- Like last year, series points and series standings will be administered by They will use the same series points system.
- Points will be awarded 30 deep in each category.
- Best seven out of eight races count toward overall results.

- 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).
Some Important Safety Notes and PIR Rules:

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! Hence, it's not worth taking unnecessary risks that might result in injury. On the motorcross course, use proper pump 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 around 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) Be safe when crossing the track. On Monday nights between 6pm and 8pm there are ongoing road bike races on the PIR race track. Unsafe track crossings have been a recurring issue during last year's series. We urge everyone to use the bridge whenever possible to get to and from the motocross course. If you prefer to cross the race track through the main gate, you should use extreme caution, both on your way in and on your way out. Always look both ways and don't cross the track when oncoming road racers are in sight. Please respect the crossing marshals' instructions whenever they are present.

5) 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 food stand is open, you will be able to buy beer from them (besides soda, ice cream, hot food and snacks).

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