Legs have run off
I am writing this for a friend. He has been a runner for over 40yrs doing marathons etc. Recently he has started doing triathlons and he is now struggling to run not just as part of the event but running in general. I know that some runner do see a change when doing Tri???s with their running but he is starting to worry. Does anyone have any advice on how to help either with training, pre or post runs or anything else. All help with be greatly appreciated.
