Confessions of a Mouse....
At Copenhagen last year, I clearly over hydrated once I got off the bike to compensate for hardly drinking whilst on it. On the run, I went for a big wee (in the portaloo) twice a lap, every lap... apart from the second wee on the last lap where I was just so fed up and wanted to finish I held it for a bit longer and did a wee in the shower lorry at the end.
I'm sorry I'm a bad mouse.
(Everyone else had finished by then anyway.)
