 Yeah, hydration was a big thing for this swim. This was by far the hottest swim I've ever done. The water was like 15 to 20 degrees warmer than most of my swims. And the air temperature was even hotter than that. And Joe and my husband and I had talked out a kind of big plan of hydrating a little more aggressively than I do in other swims. So every half hour, they signal to stop and throw me a water bottle that's attached to a line so they can pull it back.
