Just finished run 3 of week 1. Ran every other day and it went okay considering it's been a couple of years since I did any exercise. Well, fifteen to be precise. The 90 second rest periods were just about right to get my breath back before going again. Feeling good mentally but my knees and calf muscles were quite painful today. This is not surprising given they're carrying so many stones of weight. Just contemplating when I should do my next run? Wouldn't mind giving it a couple of days for my muscles to recover but don't want to lose any early progress I've made fitness-wise. It's Thursday today, so thinking of Sunday for the next one. Any advice from more seasoned runners?
