UNTIL.... I saw the track's gate was open! I can't even remember the last time I ran on a track — it's been at least a couple of years. There was no one there to tell me to leave, so I enjoyed 10 quarter-mile pickups (well, as much as you can enjoy them) every other lap. I didn't really have a goal pace, just "faster."
I also enjoyed the GPS in my Garmin Connect after the fact:
