I started c25k some months ago, got up to week 3 twice before giving up because of lack of time/holidays. So I am on my third go and determined not to bgive up this time, finally up to week 7 having repeated weeks when I just felt I wasn't ready for step up. have completed a 25 minute run , but am struggling to repeat it, I just don't seem to have the energy in my legs. Have been keeping up the running every other day and feel like my legs should be used to it now. Does anyone else have the same problem, or thoughts on the subject please?
