I'm only 5'1 & about 12 stone so I'm no skinny minny but I know how to run & walk 22 miles without stopping for any more than a couple of minutes at a time!
It's only recently that my workmates on the buses have discovered my 'secret life' & some are shocked. They come out with 'oh, YOU run? What, Every two night for 22 miles at a time?'
Urmmm yes!
'But you can't because your fat!'
I CAN & I DO, so there! And I'd rather be fat than obnoxious!
I look at their thin or skinn frames & say 'you are slim, you have a lovely figure (to both male & female) but come on a 22 miler with me & we'll see who is the fittest of us!'
They suddenly decide they urgently need to go on duty or make a cup of tea!
My husband & ex think I'm lovely as I am & my son, slinky, does seven + miles walk at a time but they don't believe him about his walking as he's so slim & slinky, they think he'll break!
However I do draw a line at shorts & sleeveless running wear. It's sweatshirts & trousers for me at all times while in public even though I run alone in the early hours in the pitch black!
