Well I'm late 50s and still hoping to improve :) I came late to running and I think it is helping to keep me in shape. I just seem to suffer with various aches these days. I think most people should be able to do 10km with some training. The pace should not be a priority really as you can always work on that. Being able to sustain your pace should be the goal initially.
I am not really a team sports guy. I am quite happy running on my own, but will run with others at times. One of the guys at parkrun was saying he doesn't want anyone else pacing him when he's training. He's about my age, but a bit quicker now as he trains for a marathon. I'm not up to that for now.
