Went out today and stretched the comfort zones down some hills and am delighted to report a max speed of 28mph. This is a triumph! Thanks to everyone for last week's advice. Lots of it ran through my head at various points, including shouting 'wheeee' which I actually did, and it made me laugh so much I relaxed a bit and went faster!!! I did actually whimper with terror at one steep moment, so a long way to go, but am feeling quite whizzy tonight!! Thanks again.
