Yes, thank you. I tried to run a mile in 8 minutes twice today. I have to run tomorrow morning to make a high school sports team. I've been jogging outside all summer -- no problems. Today ... both times, I got this horrible pain at the bottom of my esophagus. It caused me to gag -- thought I was going to throw up -- and I had to stop running at .5 mile the first time. I barely finished this second time and the pain left me gagging on finish. What's up??
Sorry, I forgot to mention that I'm almost 16, female, 5'6", 130 lbs. No medical problems. Is it possible I'm just a little too "psyched" for tomorrow morning's run?
