I have just completed week 3 of C25k and am really struggling with foot and ankle pain. The best analogy I can give is that every running step feels like bone hitting concrete. Not good!
I am 46yr old man, slim, and I cycle between 80 – 100 miles a week commuting to work. My wife suggested it may be that my legs are used to a certain motion when cycling so the muscles are tending to want to move them in a way not suitable for running. I had this problem from week 1, and am running on alternate days, with 1 day break in between, but it isn't getting any better. I find after the 5 minute warm up walk I can barely run even the first few steps due to discomfort, but just grit my teeth and carry on, although by the end of the last run (3 mins now) it is a little easier, but maybe that is the relief of knowing it is nearly over!
In the past I have run with no problems – 2 years ago I used to be able to do about 4k - but I didn't cycle regularly then. I am running in trainers I have used previously to run in, so don’t think that is the cause.
I’m going to rest up for an extra day or so before trying again at the weekend, but really hope I don't have to give up.
Any thoughts or advice would be very much appreciated.
