Notes
Barefoot. Sand.
FREEZING. Air temp 42 F. Water temp 75 F.
Interesting experiment. I wore a hoody and a beanie for this run and carried a pair of socks in case my feet couldn't handle it. I was warm and feeling good until I turned around and was running towards the current instead of with it. Water splashed up on my shorts and a few minutes later I started feeling cold. Not good, lol. The warm water kept my feet warm and I made it back no problem, but it wasn't the most pleasant experience.
I don't think I'd run barefoot in weather much colder than this.
