Sunday was a nice winter day for an outdoor workout. I spent 90 minutes mixing things up by jogging hills and doing high intensity interval training (HIIT) at the school complex.

The workout:
1 mile warm-up walk
1 mile jogging around the elementary school bus loop (5 laps). That loop is not flat - nice uphill and downhill grades.
3 100 yard runs up "murder hill" on the cross country track (very steep)
Jogged .5 miles up the slightly uphill grade between the football field & HS
10 120 yard sprints at the Middle School track
1 mile cool down walk

Distance: 6.2 miles -- HIIT + jogging + lots of walking
