Yes, I was there. I've just looked at my programme. As BOBBATH says the start was delayed because of a dispute over pay. Here are a few comments I wrote on my programme:
"Good Heavens! They've actually started at 8.35. Rain started 8.36." (However the first race saw a new track record of 72.4 seconds set by Nigel Boocock.)
Heat 3 "Run in pouring rain"
Heat 5: "Charlie [Monk] from 4th to 2nd last lap" (overtaking Ronnie Genz and Bill Andrew)
Heat 9: "Took 15 minutes to run." There were two exclusions. But then, "Best race so far"
"No interval because of weather"
Heat 14: The race was stopped. Ronnie Genz and Jimmy Gooch were both excluded then Gooch was unexcluded. My comments, "Boocock was beating Briggs by miles in the first race, also in the second race but Briggs took him from the back and went miles in front."
The trophy was presented by olympic gold medallist, Mary Rand and Editor of the Sunday Mirror, Michael Christiansen.
