I've just plucked up the courage to go to a 'proper' running shop. The bloke in there said that I "have a heavy build, for a runner". I was so embarrassed, I wanted to cry there and then. Also not helped by the fact that the only other person there was a sylph-like woman who looked like she could give Paula R a run for her money.
Stupid heavy body. Feel like there's no point in even trying any more. I;m rubbish and slow anyway.
