No certified marathon is 42.195 kilometers long. The rules do not allow it.

A road course is measured by one person on a bicycle. First they ride a straight, steel-taped stretch of road four times, to learn how many clicks of the counter on the front wheel make a meter that morning. The answer is inflated by one part in a thousand. Then they ride the course along the shortest line a runner could legally take — every tangent cut, every corner hugged — and ride it again. The two rides must agree within eight hundredths of a percent, and where they differ the shorter one is believed, and the finish moves until it is satisfied. Last they ride the taped stretch four more times, because the tire has warmed across the day, and whichever constant makes the course longer wins.

Every fork in the procedure breaks the same way. A certified marathon is at least 42,237 meters, and the extra 42 are not the error. They are the method.

The counter is a Jones Counter, built by an IBM engineer near Binghamton after his first race, advertised as twenty kilometers, came up a mile short on his car's odometer. His nine-year-old son assembled them for a dollar apiece.

The method has teeth. In December 1984 someone re-rode the 1981 New York City Marathon and found it about 150 meters short. Alberto Salazar's 2:08:13, the fastest marathon anyone had run, stopped being a record three years after the fact. Nobody had cheated. The course had been short all along.

I like that the fastest people alive run a distance fixed by someone at cycling pace, hugging the curb, pretending to be greedier than any of them. Whatever the winner ran, the bicycle ran it first, and farther.

The final piece of cake acquires rules that did not apply to the rest of the cake.

Earlier, you could simply take some. Now taking it means finishing it, and finishing it makes an announcement about everybody else's appetite. You are volunteering to decide that they have had enough.

I find the usual compromise — cut it in half — almost unbearably funny. It preserves the possibility of cake for another person while reducing that possibility to a smaller and smaller physical object. Nobody has to admit to wanting the last piece if the last piece can keep being manufactured.

There is care in this. There is also a little vanity. Leaving something for others and being seen to leave something for others make exactly the same crumbs. I don't think anyone at the table needs to sort out the proportions.

What interests me is how an offer changes the situation. "You have it" can make the cake edible again. The amount of hunger hasn't changed; somebody has just taken responsibility for the ending. I prefer that small bit of bossiness to the indefinite public display of restraint.

The cake is now too small for a fork, but someone has gone to find a knife.

The best race in Paris disqualifies you for running.

In the Course des Cafés, servers cover two kilometers through the Marais with a tray in one hand: coffee, a glass of water, a croissant. Speed matters. So does arriving with breakfast unchanged. At the finish, judges inspect the tray. The clock is only half the result.

This is a wonderfully severe definition of service. A sprinter could cross faster, but speed that announces itself is useless here. Running is a confession that the course has become more important than the tray. The job is to move urgently while keeping urgency out of what you carry.

The race began in 1914, disappeared from Paris after 2011, then returned in 2024. The fastest man that year finished in 13 minutes and 30 seconds. That is a nearly comic pace for someone forbidden to run: the hard walk of a person who knows exactly which table has been waiting.

Most races accumulate evidence of effort — sweat, collapse, the ugly lean across the line. The café race makes effort erase itself. A good finish looks like nothing happened. The water is still in the glass. The coffee did not learn how fast it was moving. The croissant arrives innocent.
