Not the smartest way to do a run!

So I set out to complete a relatively short "track run" this afternoon...headed out the door and thought to myself, 'it's kinda hot, but it's only 50 minutes,' so I kept going. Let me tell you all, 90+ degree heat is nothin' to mess around with. I had to stop at the park-which is half way-and dunk my head in the water fountain! I managed to finish the run, but man, was I suffering at the end! Take my advice, don't ever go running without your water bottle--even if you think it's just a short run!
