Started C25K at the beginning of this year in the depths of January and managed to graduate. However through the late spring / early summer I suffered badly with my knee and couldn't manage more than 10mins solid running. A few weeks ago decided to give it another go, I can't be a couch potato all my life and job at work has become far more sedentary. As I live in the middle of nowhere I had to do my winter running last year by driving to the nearest village to find some street lights, I was extremely lucky as most of my running was completed on an evening and last winter was positively mild so not too many icy days to contend with. This time round I've invested in a treadmill to try and cut down on the time it takes to get somewhere suitable to run in the dark and with the icy weather we've had seems it might have been a good idea.. Does anyone else use a treadmill? Finding it really hard to know how fast I should be running, had this problem before last time I did C25K too, but thought the treadmill would help with this, also I find it incredibly boring and time seems to slowdown, any hints tips or ideas for me. Can't wait for the better weather / lighter days and nights to return, currently in the middle of week 4.
