Such is the way this man is – no fuss, no non-sense and down to earth.
But Guy’s record attempt that was broadcast live on Channel 4 in the UK could have gone terribly wrong, even though he played it down.
He circulated around the wall at 78.150mph (125.7 km/h) on a BSA engined bike built from bits and pieces in his own workshop.
His body was subjected to forces of around 6.5G, and Guy felt himself blacking out after a couple of laps on each run.
Guy set himself the target of officially breaking the 80km/h barrier. He reached that speed in a practice run in the morning.
During first official run he recorded a speed of 71mph, his second scored him the official record.
Guy was meant to only do two runs, but decided to try one more time and couldn’t do any better.
Still, he has been credited with a world record, and celebrated the feat with a cup tea.
