You put the number in either Transition 1 ( swim to bike ) or Transition 2 ( bike to run ).
You'll keep the number on a 'race belt' ( elastic strap that you pin/attach the number too before the race ). You put on the race belt in one of your transitions.
Some races want you to wear it on the bike, some don't require you to, and you just put it on for the run. Depends on your race, read the guidelines for the race, or ask someone else that is doing it.
Race belt will be about $5 or so, and you re-use it for every race you do. Ask at your local running store or bike/tri shop. Or order online if you don't have a good shop close by.
