I used to look at runners/joggers and wonder why they were doing it when they usually look quite miserable. now I realise they are simply concentrating. I can't believe how much concentrating I need to do when running. I need to concentrate on breathing, relaxing my shoulders, foot placement, speed, not falling over. I can't listen to music when I run, the other day I needed to take my gloves off and it totally put me off my stride and it took a couple of minutes to recover. is this just me or do other people have to do the same? on the plus side it is good to have that time when you are not worrying about the day to day troubles.
