How am I meant to wear a race number?
Officially, race numbers must be clearly visible at all times during the race. That means it’s not under your vest or folded up. There are a whole host of reasons why this is required. For example, a race numbers lets the sag wagon know who is still out on course or if grades are mixing. It is important and covered in the Technical Regulations under Section 1, rule 3.3. Race numbers are the difference between you and that joker sprinting into Mordialloc. Wear it proudly, you are for real.
