Back after a few days out from a stomach bug last week. This wasn't a very good run. I wasn't exceptionally tired while running, but with a mile left I was really lightheaded and felt like I was going to vomit. I decided I'd walk the rest, but practically fainted in the middle of a busy intersection as I crossed the road. I literally don't remember how I got across the street... talk about scary. I know I hit the "walk" button and was supporting myself against the signpost. I guess I was conscious enough to walk when I had a walk signal, but apparently I blacked out while crossing because I remember panicking when I realized I was still moving but I couldn't see and everything sounded muffled. Terrifying realization, and I'm so glad nothing bad happened. I stopped at a Wendy's to get water and then walked the rest.
