In Case You Were Wondering.

If it's around 7:30pm and still 98 degrees outside, it's not a good idea to go running no matter how guilty you feel for skipping your morning run.

It's also not a good idea to try and use grapefruit juice as a sports drink. 

Grapefruit juice + hot weather + running = everything fine one minute + feeling like you are going to hurl the next. 

Seriously, don't do it.
