A crash at 142mph is fairly reasonable in anyone's book. At Mugello, Silverstone, Brno it would be noted and not given a second thought. A slide across the track, maybe, and into some welcoming gravel. On Mona's Isle, however, it is a different story.
Simon Andrews crashed at that speed on Saturday. He misjudged his velocity on the entry to Graham Memorial and ran out of two-lane blacktop. After hitting a bank and laying in the road for probably longer than was entirely necessary, he was taken to hospital with nothing more than a broken ankle, wrist, shoulder and blood in his eyes. He should be dead.
But this is the Isle of Man. A place where Giacomo Agostini raced Mike Hailwood raced Phil Read, once upon a time. It was a Grand Prix. Not so now as the dangers of the place proved too much and Barry Sheene, who did just one lap of the place on a 125, was instrumental in it being removed from the calendar.
Heroes are made here. But they are only heroes in certain places. John McGuinness has now won 19 TT races. Those who follow MotoGP in Spain will have no idea who the man is but McPint does six laps of the 37.73-mile circuit at average speed of 129mph. Read it again. Average speed. On normal roads. His lap record is 131.5mph and tomorrow it will fall, so long as the rain doesn't intervene.
The Isle of Man was ridden on Wednesday by Randy Mamola and Kevin Schwantz in a parade lap. They came back with eyes like saucers. And they weren't pushing. Josh Brookes, who should know better, chased three-time winner Michael Dunlop over the mountain and declared at the end he will race the TT, once he finds a team boss who will let him.
It is a legendary place, full of history, it makes you feel alive. If you haven't been, go. The TT stirs the soul. If a bike and rider coming past you three feet from your face at 180mph down a hill on a public road doesn't raise even a grin, you are already dead.
