when I started running I was self conscious, not about my body but about my ability.
I thought people would think what a crap runner I was and take the p1ss
I would run in jeans and a t-shirt, so when I when I had to walk it didn't look like I was a failed runner walking, just a sweaty person in jeans
By the time I got up to a continuous mile (1 lap of the block) I lost interest in what people thought,
I've been heckled loads of time, nothing personal just the usual run forrest run, get those knees up, etc etc.
I see all sizes, shapes and abilities running and only admire them for having a go.
