Bib Numbers

From Orienteering Wiki

noun, are provided for the Elite course competitors, and for relay competitors. They are only ever worn on your chest (that doesn't mean on your skin), and will be attached with the sometimes provided safety pins. Some runners seem to delight in losing their number in the forest. Don't be surprised if you are asked to return your number and pins at the finish.

At relays the number will also be colour coded, normally red for first lap, white second lap and blue last lap.

The premier relay classes for men may have 4 laps (Green/Red/White/Blue)
