-Right before you go out on your run, weigh yourself naked on a very accurate scale.

-When you return home, strip down and weigh yourself again.
-Subtract your pre-run weight from your post-run weight. Multiply the number of pounds lost by two. That’s the number of pints of water you need to drink per hour (during your run or immediately after) in order to stay properly hydrated.
