I had my name on my shirt is great when the crowds are cheering you personally! The headphone people bug me too they have no idea what's going on around them or whether anyone is trying to pass!
We were there yesterday to see our neice and nephew run, and we did wonder why people bothered having their names on their shirts then wear headphones.
There were still a lot of people queueing for the baggage drop and toilets at start time, I don't think they were all there for the ultra. Nevertheless, tempted to register my interest for next year . . .
