So...a group of colleagues and I today did a 'beer run'. Essentially a pub crawl, here in Asia we did a 2 kms run where we drank beer, ran a bit, drank more beer, ran more until the end Only, somehow I found myself covered in wee. How is this? I am fit. I regularly run 5 kms and this was only 2kms. I have however had 3 natural births, Never have I had an issue with incontinence before - so what's happening here?!
