Even though in some races nowadays, body marking comes together with race kits in the form of temporary tattoos, it is still common to have this body marking process on the morning of the race itself. In some races, number stamps are used, while in other races like this one, a big fat black marker is used.
I read some articles in which some athletes disagreed or question about the purpose of body marking. The points being, it is covered anyway by the long suits which athletes are wearing during swim leg (in colder places) and for bike leg, numbers are displayed on the bike and helmet, while on running leg, it is clearly displayed on number belt or on the shirt.
But for kiddie triathlon, let me tell you, it’s a cool thing to have body marking. The kids are proud of it. If it’s possible, they don’t want to wash the numbers off until Monday when they go back to school, so it can be the subject of conversation during recess time :-).
