Perhaps I have just found out the reason why since the start of 2015 I have had quite a lot of stiffness in the ankle which has not gone away. Last year the sports physio told me I needed a pair of shoes with a lot of rear cushioning (because of tight calf muscles), and this was provided after great service at the running shop in Carlisle. It seems I might have used up the cushioning in 9 months when I now compare the new with the old. So check your soles any one who is getting niggles.
Fingers crossed by the time of the Richmond 10k in four weeks time the ankles are back to right.
Enjoy running this weekend.
