Hehe, one of the lovely people who came to support me at Brighton said how hard it was holding up a sign when it was so windy ... and then said "not as hard as running a marathon, obviously!" It did make me chuckle 
I'm super-excited to be supporting on Sunday, really looking forward to meeting everyone and cheering on all our runners. I know Vik has said this, but being involved with the VLM support crew is the BEST cure for post-marathon blues ever.
I can't wait to go to the Expo either, I missed the Brighton one because I got there too late on Saturday. I saw some people running with visors they bought at the Expo - very jealous! Hope they are also available at the London one.
