Hello. I just wondered if you could give me some advice on what I should be aiming for. My situation: I am late forties, have always been unfit, started C25K last Winter and now run a very slow 5K twice a week (40 minutes). I don't know where I should go from here - should I be looking at going faster? Doing something else? I am a bit worried because my knees are rather creaky (can I do anything about that??) My aim is too maintain fitness without knackering my joints. I am wondering whether swimming too might be good to increase overall fitness. Or maybe weight training? I don't like yoga! Basically I don't want to become super fast or super strong but I don't want to lose the fitness I have gained either. Thanks!
