His audience laughed appreciatively. Cunningham was spent.
The self-transcendence race is 3100 miles (4989km) long, or roughly the same distance as running from Cape Reinga to Bluff two-and-a-half times. Established by spiritual leader and fitness fanatic Sri Chinmoy, every year it's typically run by a dozen or so of his keenest followers. They have 52 days to complete the race, running 18 hours a day through heat waves, storms, aching boredom and with aching bones.
Every day for the past month and a half, Cunningham ran an average of 114km. A race in which each competitor wears through 10 pairs of running shoes is not an entirely appealing prospect.
I remember an apt analysis likening my jogging technique to that of a wounded pterodactyl, and there are few things less enticing than the thought of running a marathon with the word "ultra" slipped in front of it.
Even more so considering the New York course, described as a lap around a suburban New York block, is repeated and repeated and repeated. One lap is 883m. Each competitor runs that single lap 5649 times. As the name suggests, it is less a journey around the block, than a journey through one's own head. In his fourth self-transcendence, Cunningham knew what to expect. He lost toenails, his achilles caused him problems and he developed a ghastly rash. His feet swelled, he shed weight. But with 10 other competitors, he kept running until his self-transcendence was achieved.
In the hours after he finished, I asked a race organiser how Cunningham was faring.
"He's really wiped out."
Fair cop, I thought.
But the race itself still isn't over. As you lap up the last of the Olympics, there are still competitors trudging around and around a block in New York City. What a journey it must be.
And though every four years we marvel at gold medallists and our species' finest athletic specimens, in suburban New York a handful of runners know that no muscle can match the strength of that blobby mass between your ears.
