220's

For our Friday morning run we did intervals.

Well, we ran 220 yards (1/2 lap) and walked 220 yards.

We did six 220 sprints in all, and made all of them in between 55 & 65 seconds.

Our walking 220's lasted about 2 minutes & 20 seconds.

Friday Intervals

Run 220 - Walk 220 - Run 220 - Walk 220
Run 220 - Walk 220 - Run 220 - Walk 220

So our total workout lasted 20 minutes. We were ready for it to end.
