I did not do well, my calves tightened up very badly within 2 minutes into the first 5 minute jog. So I stopped to stretch, decided it was too much and restarted week 3. Each run at the end of week 3 is 3 minutes so I am adding a minute to the very last run to build myself up. So week 3 day 1, on the last run I did 4 minutes instead of 3 minutes. On week 3 day 2, on the last run I did 4.5 minutes instead of 3 minutes. And tonight, on week 3, day 3, I did 5 minutes on the last run instead of 3 minutes. So it built me up to 5 minutes better and now I can attempt week 4 again on Monday, knowing I can do 5 minutes!
