The most remarkable skill of truly great motorcycle racers is their ability to compartmentalize everything. Break down every situation, put each part into its own separate container, and not let one thing bleed into another.

Private lives – often messy, sometimes chaotic – stay in the box marked private life, and don’t cross over into racing. Pain stays in the section reserved for pain, and is not allowed to encroach in the part set aside for riding.

Crashes are to be analyzed, understood, and then forgotten, but not to be allowed anywhere near the part of a racer’s mind where they keep their fears. That is the theory, at least, and the better a rider can manage to live up to the theory, the greater their chances of success.

Marc Márquez gave a masterclass in the art of compartmentalization during qualifying at Valencia. The Repsol Honda rider went out on his first run in Q2, and on his first flying lap, lost the front going into Turn 4, the first right hander after a whole sequence of lefts.

It looked like a harmless low side, of the sort which Márquez has so often, and which he usually escapes without harm. But whether it was due to the bars being wrenched out of his hands, or due to his arm being folded up awkwardly beneath him as he tumbled through the gravel, he managed to partially dislocate his weak left shoulder.

He got up out of the gravel in obvious pain, doubled over and shambling towards the barrier. Once behind the tire wall, he was picked up by his manager and mentor Emilio Alzamora, and taken on the scooter back to the paddock.

He was rushed up into the Repsol Honda truck, where Dr. Mir examined him. He suited back up, put his helmet on, and went and sat in the garage, as his team held his second bike ready to go.
