Every race participant must utilize a season plate for race scoring and timing. After registering for an event, you will be asked about your season plate status. If you pre-purchased your plate through the website or you picked up a plate at a previous event, then put your number in the box provided. Otherwise, select “Yes, assign a NEW plate.” if you do not already have one.

    We realized we left all our race plates at home and are already registered online for the race. What are our options as far as getting race plates for tomorrow’s race?
