Before I did my 10km last week I had been working a bit on speed and it seemed to be making a difference. The one thing that seemed to happen as I speeded up was my ankles activated and moved. I now have a feeling that this is how most people run and I maybe shuffle rather than run. I am working on using my ankles to push off more but I am finding that they are quite tired as I don't think I have been using them properly for a long time. Do you all run by using your ankles? Am I trying to do the right thing here or not?
