Hi, guys. I have only just started running and recently done a off road run race. (10 k). I am now in training for the Chester half marathon. But im finding training for this a lot harder than the off road run i did. Tarmac seems to really hurt for days after. Im actually limping now two days after ive just done 7k. i don't have a problem running 10k but getting fed up of days of pain. So am i doing too much if so how much training do you think i should do a week and how far. Thanks Lee.
