How fast can I go???

Well, last night was a night for speed. After a 7 minute warm up I did 3 minutes flat out then a 5 minute ultra slow cool down. I ended up at 1 7/8 miles in the 15 minutes and just under 1/2 a mile in the 3 minutes. Let me say, I was spent at the end but after the cool down ran a quiet 3 miles because it was such nice weather, a light rain and low 70s.
