I'm in my early 60s and really enjoying the programme. I've done Week 5 Day 2 and was getting a bit uptight about a 20 minute run as I had a slight touch of tendon pain/discomfort in one leg. So I decided to take a few days off to be on the safe side. Now I've developed a chill with sore throat etc so I expect I'll be laid up for a while. I'm wondering what to do when I get back to the programme : should I play it by ear and see how it goes? I'll probably be out of action for 8 or 9 days in all. I'm really enjoying my new level of fitness :I really wasn't ready for hobbledy old age--not just yet. I'm pretty healthy, thank God, and I'm not overweight. Knees are slightly dodgy betimes and, strange to say, I find the jogging easier than the walking! Thanks for all the tips and help, and for a wonderful programme too.
