Online registration for Short Track Race # 8 (July 29) has closed, but you can still register at the races on Monday.

Online Registration for a Single Race:
- Each week you can register for the next upcoming race.
- Online registration for each race will be open from Tuesday am through Saturday 12pm (Noon), the week before each race.
- If you have pre-registered online and ultimately can't make it to your race on Monday, we gladly let you transfer your entry fee to a later date. Just send an email to and we'll get it all figured out.

Day-of-Race Registration:
- You can register at the race from 4:30pm to 15 minutes prior to your start time.
- The registration tent is located on the infield of PIR near the start/finish area.
- 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).
- Please schedule enough time before the start of your race, as lines can be long at the first race of the series.

Whether you plan to register online or at the races, please make sure to fill out our online series waiver and accident release form. This document need to be filled out by every racer, but only once for the whole series. If you are not sure whether you have it already filled out or if some of the data on the form have changed during the course of the series (like your emergency contact and phone), please take the time to fill it out again, so we can update our records with the most current information.
