I have given my water intake recommendations before; half of your body weight in ounces (although I prefer a gallon a day). However, as I am sitting in our 100 degree Florida (which feels like 200), it occurred to me that I need to give an additional recommendation-
If you live in (or are visiting) an extremely hot climate like the southwest or southeast, and are exposed to the heat for extended periods of time throughout the day, I encourage you to drink considerably more water than you usually consume.
Your body will lose water at a much faster rate in intense heat, and you may become dehydrated much faster. The goal EVERY day is to never be dehydrated (which you will achieve if you are consuming at least half of your body weight in ounces).
On top of your normal intake, you will probably need anywhere from around 30-60 ounces more water in hot climates. Listen to your body, but remember to avoid waiting until you are already thirsty...this is your body's way of telling you that you are already reaching levels of dehydration.
Train hard, and enjoy the journey!
