I'd wager a guess

Reached for the archives for this one:

On the track...

I began with an 8:30 mile, continued for another two miles at 8:00 pace, did a fourth mile in 6:58 (10K pace?), a fifth mile in 8:00, and a sixth mile in 6:07 (was supposed to be 5K pace, but was too slow).  Twenty-four laps wasn't that bad!

I'm not quite where I was four years ago. I'd wager a guess that I'm about 30-45 seconds slower in the 5K.

Four years ago on Thurs, 11/2 I reported:

Since I (read: my wife) was feeling a little uncomfortable running in the pitch black on the mountain, I took my legs to Hillsborough HS.  I was supposed to do 60 minutes steady, but I swapped out the plan for a little "up and down action."  I ran three miles around the track at 8:00 pace, a fourth mile in 6:25 (was supposed to be 10K pace, but was too slow), a fifth mile in 8:00, and a sixth mile in 5:55 (was supposed to be 5K pace, but was too slow).  Twenty-four laps dragged!
