NEW YORK: It’s the world’s longest certified foot race: a 4,989km run that takes participants around the same New York block 5,649 times.

Thousands of people have climbed Everest – but, organisers say, just 49 have completed the Sri Chinmoy Self-Transcendence 3,100 Mile (4,989km) Race.

Runners finish more than two marathons a day for almost two months, on less than five hours sleep a night.

They can’t rely on changing scenery to keep them motivated as the route is a half-mile loop on a concrete sidewalk around a high school in Jamaica, Queens.

To mix things up a bit, they alternate daily between running clockwise one day and anti-clockwise the next.

“Definitely monotony,“ said this year’s winner, Andrea Marcato, describing the biggest test of the race.

“The first week is quite challenging, especially for the mind. But after a while you get used to it. You have to accept that every day is going to be the same,“ he told AFP.

Participants have 52 days to run 4,989km, meaning they must average 95km every day.

They run, walk and hobble between 6am and midnight, eating as they go to make up for the estimated 10,000 calories they burn during every session.

For the day’s other six hours they sleep, wash and care for their blistered feet in nearby accommodation.

Only ultra-marathon veterans who have completed six-day races are allowed to enter.

“It’s a test of stamina, strength, inner determination, and talent,“ said race director Sahishnu Szczesiul.

Harita Davies, the sole woman of this year’s seven competitors, said the race takes a physical toll but “the kind of unbelievable thing is that as the days and weeks go by your body actually does adapt, you do get stronger.”

Indian spiritual leader Sri Chinmoy, who lived in New York before his death in 2007, founded the run in 1997.

He advocated “self-transcendence,“ using spirituality to go beyond the limits of what an individual thinks they can achieve.

Runners in the 25th edition, which began on Sept 5, said achieving a meditative state was key to completing the race.

“If the mind is focused, you don’t have other thoughts or fears or worries or doubts,“ said Marcato, 39.

Forty-seven-year-old New Zealander Davies listens to music, audiobooks and recordings of inspiring quotes.

“When you first come here you think oh my god it’s a concrete jungle. But you can find beauty everywhere. You can look at the sky, the trees, the birds, the people,“ she told AFP.

The runners, who are also from Japan, Taiwan, Slovakia, Ukraine and Russia, have a small aid station at their disposal where a doctor is on hand to tend to blisters and shin splints.

Volunteers hand participants copious helpings of food – from healthy vegan meals and juices to donut holes, ice-cream and sometimes Chinese takeout.

An RV with a bed provides for quick power naps while a rickety scoreboard displays the number of miles completed by each runner.

Supporters come by to clap while residents shout words of encouragement, although not everyone is sure what is going on.

“I grew up here and had no idea that it was a race. I just figured they were really into jogging,“ said 34-year-old Julio Quezada.

The race returned to New York after occurring in Austria last year due to the pandemic. – AFP
