Lotsa tabatas

Was thinking of doing this WOD, which is to keep doing tabata intervals until you've covered 2 miles. I didn't do it as prescribed, but it was still a good amount of work!

Warm-up: 8 minute jog ~ 1 mile
12 tabata intervals, 1 min rest
4 intervals, 1 min off
4 intervals, 1 min off
4 intervals, walk the rest of the way home

I covered at least a mile and a half. Calf/ankle felt okay once it got warmed up, but started hurting quite a bit by the time I got home - I guess it was tightening up again? Foam rolled it (very gently) and am icing it now.
