Yesterday, I was on the cool down of a ten mile run with six miles of fartlek style intervals and I must have passed out and fell. I was on a bike path and a lady stopped and got me back to a YMCA where I started. I was still not very coherent (couldn't operate my own phone) and had a bad headache so they called an ambulance. The ER tests came back normal and I am going to my primary doc today.
I still don't remember everything but bits are coming back and had a bad headache all day. My stomach hurt at the hospital but felt better after a couple hours. I had a couple of scrapes on my shoulder and knee but nothing bad.
Anybody ever experience this? How did you recover? It was not hot. It was very mild/cool for August. I did the same I do every morning for the last eight years of morning runs and I have been running almost 20. I took some caffeine but I have been doing that once a week for years and I do intervals once a week as well.
