Text Message Race Notifications

Last season we used SMS/Text messages to communicate with racers when there were major changes or delays at our races.  For 2019 we will again use this system and you will need to sign up again for notifications.  Please follow the link below to sign up.

We will only use this system to tell you if the race has had a change in the following:

  • Cancelation - the race will NOT be held.
  • Change in Race Times - the race will move the race start times, but the race will go on that day.

For all other normal notifications you will want to check our Facebook or Twitter feed.  We also send emails with the latest news and you can signup on the home page of our web site.  If you choose to sign up for this we hope you will never get a text this year, because all of the races are going as planned.
