Sat 19th April - Rapha Roller Race, 7pm > Half midnight

so the record was beaten by 2/100'ths of a second but aren't the timers using hand held stopwatches?

I imagine it added to the excitement on the night.

Whether it is statistically relevant is another matter. It sounds like it was a very successful night, I'm sure there will be opportunities to 'settle scores' later in the summer.
