Sunscreen that stays?

New to OW swims longer than what's in an Olympic tri and am registered for 2 this spring. I'm worried about frying my back and legs. What is a good sunscreen/block that stays put for a couple of hours? Thanks in advance. You guys are so inspiring (and funny in places).

  • For swims lasting under 2 hours, I use Banana Boat Sport 50 spray, usually two coats. Over 2 hours, I use Coppertone Kids pure and simple 50, which has zinc oxide in it. That is probably the most important ingredient to look for.
