The Skinny on Race Numbers

Triathlon Event Hello, thank you for maintain such a wonderful web site. I’m new at triathlon, do I need to wear the race number during the swimming session? if yes, where is the most common place? thank you so much in advance for the answer.

Triathlon Event Hi Roberto,

Thank you for contacting and welcome to the sport!

  • You put the numbers on your bike (paper and/or sticker)
  • You attach numbers to your outfit: shirt or shorts (paper)
  • You put the numbers on your helmet (sticker)
  • You have the race organizers write the numbers on your body: both shoulders and your thighs (Sharpie marker)

Good luck with your triathlon and please let us know how it goes!

Be well.
