hi, just looked at race number and it's 58043 (so i expect everyone to say hello to me ;)
i'm not too fussed if it's just a few minutes at the start, it was just that i was talking to a friend who did it last year, and she said she was walking for ages, but then again, she did 5 hrs something, so would have definately had a different start going by all the above...
it looks like just a bit of a forced warm up...that's cool.....on my last marathon it was freezing and i'd been waiting around in the cold for 2 hours so needed a warm up...did the first mile in 10 minutes!
