So I was due to start week 4 of C25K at the beginning of this week, but had to stop for a while due to an injured leg (bad muscle pull). Leg's mostly better now but I'm wondering how to get back into it - I really want to finish by Chistmas. I did a quick 15-minute jog yesterday alternating 90 seconds of jogging then the same walking, but am now debating whether to repeat week 3 or go on to week 4. Also, I'm finding it really hard to motivate myself now that I've broken the cycle. Any advice?
