I was there - on track! A Golden Muppet on TV!
Too old to run now, but was called in as an official, I was doing my usual job as a marksman (starter's assistant) and if you look on the BBC website the 2 minute highlights
http://news.bbc.co.uk/sport1/hi/athletics/14101558.stm you can see me stood behind Mo Farah at the start. To the left behind Barras.
It was a great atmosphere and much better than Gateshead and Crystal Palace (where the car park takes even longer to get out of).
Had some fun and games in the last 100m. We DQ'd an athlete who tried to get back in after a second recall. I resisted the temptation to tell him to bugger off and he was taken off by others.
Not sure if I'll be there for the trials but I'm going to be in London in just over a year's time. I'm in the call room not on track.
