I'm a relatively old lady (63) and it's taken me 6 weeks to get to week 3 of the plan. But I just ran for 3 minutes without stopping! I am feeling quite proud of myself - I was a bit scared at the thought of 3 minutes, but it wasn't so bad. I'll probably never get to the full 5k, but every bit of exercise helps. I probably look lumpy and wobbly when I run, but I'm enjoying every minute so far.
