Liquids lost swimming in hot water distance swim?

Given water is 87 degrees Given air is 90 degrees Distance 2 miles Time swimming time around 50 min. How much fluid will be lost (sweat)? Anyone want to hazard a guess? I am thinking 3 pints? = 3 pound... I plan to weigh myself prior to and after the race. Results should be interesting.

  • Into Chris Greene Lake weighing 187. Out of Chris Greene Lake 46 and 1/2 minutes later weighing 182. Five pints of Virginia "sweet tea" later weighing 187. As a homebrewer I must chime in. If by sweet tea, you mean your typical Southern brew of sugared tea, 5 pints would have left you somewhere in the neighborhood of 187.3 pounds. Water, by definition has a specific gravity of 1. Add enough sugar to make it sweet tea, and we're closer to a specific gravity of 1.06 (or possibly more). These are the kind of nerd experiments I like. They're even better when you go ahead and ferment the sugar to reduce the specific gravity back down to 1.
