Anyone else about to do it? I'm due to do it today. In the rain, by the look of it! I find it hard to imagine 20 minutes is possible - what a jump from 8 minutes! I don't want to be beaten by my mind before my body's had a chance to have a go at it though! Good luck to any of you who are also staring this one in the face and well done to those of you who have already succeeded.
