7.50pm: screech from tyres as Boeing 767 touches down at Heathrow. 8.00pm: turbines spool down as we park, clicking of seat belts being undone. Ring The Doctor: tell her I'm on schedule. Hand baggage only, so straight out through customs, turn left out of the door of Terminal One, hundred-yard walk to where I've left the Trophy in the free bike park. Rolling at 8.20pm. 9.00pm: clutching can of cold beer, I settle into the sofa to watch the last episode of The Space Race. And supper's ready. Motorcycles: the only way to fly.
