In this commento, Jeffries details one lap of the Isle of Man TT course, a distance of 37.75 miles. As you listen to his voice, imagine the cognitive power it takes to navigate this route at triple-digit speeds: you're taking an outrageously powerful machine to and beyond the limit while also anticipating what the conditions will be around the next corner, all based on your memory of the circuit, informed intuition based on miles of racing experience, and pure feel for the road. As I look at this video, I couldn't imagine maintaining control of his motorcycle for even the first 30 seconds, let alone the almost twenty minutes it takes to complete a single lap. Then imagine doing it for successive laps on end.
Racing like this isn't about a crazy guy letting it rip on a bike. What we see here is something akin to a highly-trained and exquisitely practiced concert pianist taking us through a Rachmaninoff sonato seamlessly, all from memory and without a single technical error or lapse of expression. To go on a lap with Jeffries is to understand flow and its importance. His life is on the line every foot and every second, and in the running, he is living.
