I ran with much shorter strides yesterday and found it much easier infact I was slightly quicker with a lower heart rate.So I think that will help me alot.Thanks for advice on that.My shins were still slightly painful but Im going to try running today with some arch supports which I used in my old trainers and had no problems.I've just realised the trainers Im running in have no arch supports so hopefully this is causing the problem as I have been told in past(I've just remembered!) a mild pronator.I'll let know how I get on.
Ian.
