I started a little too fast but I'd only been running 2 mi e/time I'd go to the gym before class, I was itching to get a long run done. And I was outside! It was hot and breezy and sweaty and amazing. I don't know how I used to stay inside the apartment for so long before. Never again. I added Gatorade to my water (just 1/3c) and I really think it helped, I wasn't super thirsty or ready to die. It was a little sweet, but I'll take it.
