I forgot to say what the physio said about the ankle. Well, it seems I have tears to 3 ligaments around the outside of the ankle and strained one on the inside of it. In other words, a bad sprain. It was swollen for 3 days after the injury and went a yellow colour but I am sure the prompt treatment by the St. John's man meant that the recovery started sooner than it normally would have. It is still sore to touch and I can't turn the foot to the outside easily and its now a week after the injury happened.
On a good note, the physio reckons it will heal well and not take too long provided that I do the stretching and strengthening excercises regularly.
I hope this will be the case as I seem to have entered the Draycote Water 35 mile challenge on 18th February next year. (There is a marathon option so I could always stop there).
I need a challenge to aim for and I thought that would be a good one. Not too hilly, 4.75 mile laps so no need to carry anything, other forum nutters present. Sounds ideal. Bring it on!
