OK, today I went over to the track to try to regain some of my long-lost speed as part of my 2-week Solo Training Camp.
One of the best things I like about doing intervals with my Garmin is making nice little plots of the row of even peaks in intensity (heart rate and pace) from the intervals.
This was not one of those days.
You can't tell from the plot, but this workout consisted of:
4 laps (1 mile) warmup jog
4 laps of (100m fast, 100m slow, 100m fast, 100 m slow)
4 laps (1 mile) warmdown jog
Those paces were all over the place, weren't they?
