A moment of [fill in unflattering adjective here]

I'm at the gym for the first time.  On the elliptical, but getting bored so I switch to the treadmill.  I plan to run for a short time, starting at a good pace I glance down at the display to see that I'm getting close to a mile.  I finish said mile in a little over six minutes.

I'm surprised, I'm not in such terrible shape as I thought.  I feel good for about 45 seconds...

Reasons I'm an idiot:

1) It was 1 km

2) That's about 0.62 miles

3) Meaning I was on pace to run a ten minute mile

4) I haven't run a six minute mile since high school
5) I'm clearly a genius
