If you are running this virtual race, do you fancy setting a date to do it? the 'real run' seems to be on 4th November, which would be good for me. This may be just too difficult to organise but it might be quite fun to try. Running with you would be marvellous!!
Oh, and if you hadn't thought about this... How about joining in. You can chose your distance/date. It's a great charity (close to my heart). You can collect sponsors or just contribute your entry fee (and get a t-shirt/medal). It might be a chance to use your running to do a good thing....
