I was involved in an accdent on my bike last July and got back on it on 1st January. I had put 2 stone on in weight and had just been sitting down for 6 months to let the broken bones recover.
The first ride was just 8 miles and my neck and shoulders hurt. Alot. By the end of the month I managed a total of 275 miles and a 50 mile ride. My shoulders and neck still hurt (the bones in the neck have still not healed) but every ride is easier than the last. I have increased the pace from 14mph average up to 15.5mph and although that is nowhere near what I used to be able to do, at least it is a step in the right direction. I used to like to do quite long distance rides (100-200miles) but I cant do that yet and I may never be able to, it depends how the inuries heal, but at least I can still ride and if I cant do what I used to be able to, I will adapt my riding to suit.
Now I have got a bit of fitness I am aiming to build a good base of longer miles at slower pace and see how that goes. The weight is slowly coming down, a loss of 1/2 stone in January and I am hoping for something similar in February.
