Yay, I did it! I'm a 'morning person' so had no problem getting up at silly o'clock and getting out before people are about - it'll be a while before I'm brave enough to try this at normal o'clock. But I did it, and I'm really proud of myself! I think I'm going to aim to do all the weeks twice each, so that I can get my confidence up before I start the next week - after all, I'm not in any hurry, it's the miracle of actually doing it that matters to me.
Thanks for your amazing support everyone, I was looking forward to posting!
