Hi. I'm planning on starting C25K tomorrow. I tried it before years ago and gave up around week 3. I've been reading everyone's experiences and I'm really keen to try again and complete it this time. I'm overweight and really unfit so it is all a bit daunting! I have osteoarthritis in both big toes but I'm really hoping that won't get in the way (when wearing flat shoes, I generally have low level discomfort walking, nothing too unbearable). Has anyone managed to complete the programme with this kind of arthritis?
