In his 2006 essay, ‘Roger Federer as Religious Experience’, the late, great American writer David Foster Wallace wrote that “beauty is not the goal of competitive sports, but high-level sports are a prime venue for the expression of human beauty”.

“It might be called kinetic beauty,” he added. “Its power and appeal are universal.”

Watch Kipchoge run, and you’ll see his point. It’s difficult to find a sportsperson so impossibly suited to his craft, as if his entire reason for being is to coast over the ground at 4:40 per mile, a pace that for most would feel like a sprint.

But when Kipchoge does it, his head has virtually no vertical motion, his face so relaxed that he looks bored. His arms hang loose, swinging casually, his fingers in a gentle tuck, as if holding an invisible stick. His feet don’t so much hit the ground as stroke it, his toes pushing off the road with the elegant, balletic grace of a dancer.

Kipchoge is to marathon running as Jordan is to basketball, Williams is to tennis, and Gretzky is to hockey: an absolute monster, unquestioned in their supremacy.

Have you ever run a mile in four minutes and forty seconds? How about 26.2 of them back to back?

Can I go faster in my next marathon? I don't know, but I'll certainly try. All three of my kids, though, are realistic about what it means to try to get faster as the body gets weaker every day. They are excited about what they'll feel like at 18 or 28. They're climbing up the mountain as I'm walking down.

Inventor William Cubitt subscribed to the “no pain, no gain” philosophy. His “Tread-Wheel,” which was described in the 1822 edition of Rules for the Government of Gaols, Houses of Correction, and Penitentiaries, was presented as a way for prisoners to put in an honest day’s labor. Prisoners used treadmills in groups, with up to two dozen convicts working a single machine, usually grinding grain or pumping water, sometimes for as long as eight hours at a stretch. They’d do so “by means of steps … the gang of prisoners ascend[ing] at one end … their combined weight acting upon every successive stepping board, precisely as a stream upon the float-boards of a water wheel.”

Given a treadmill workout and nothing, I sadly choose nothing all too often.

However, it is fantastic that we have the option, and I’m glad the technology is evolving to make treadmill runs feel more like “real” runs.

I do wish, however, I had one of those treadmill desks. I could see myself easily getting 30,000 steps a day if I had one of those bad boys.
