15-minutes the hard way

Run for 5 minutes. Rest for 5 minutes. Run for 4 minutes. Rest for
4. Run for 3 minutes. Rest for 3. Run for 2. Rest for 2. Run for
1 minute.

Total distance: 1,800 meters

Maintained 6:40 mile pace for the first two runs for sure. Got tired
quickly after that and had a hard time counting up all my laps let
alone figuring my pace on the last three runs. Actually only slipped
that pace on the 3 minute run. That one and the last two were
brutal. It was to get out in the Vibram Five Fingers though.
