What is the deal with number/name bibs on athletes? Watching the trials and these guys have these things pinned in all directions, some blocking their sponsor logos. Nike/Adidas pays big $ to design and develope high tech apparel, only to have safety pins poke and tear it. And what about the little numbers they are forced to attach to their sweaty quads? most do not stick and never make it the entire race.
The olympic swimmers have to stay in lanes and don't need to wear anything.
