Just over a week ago, I was standing in the Saint Barnabas Church yard in Falmouth, Massachusetts, after completing the 35th Falmouth Walk. Old home week. New friends on the walk, old friends in the yard, everyone talking the good old times.

Frank Shorter’s wife, Michelle, told me the race that impressed her most wasn’t Frank’s Munich marathon gold but his fifth place in the Olympic 10000m five days earlier. “He was this close to bronze,” she said wistfully.

But that’s the difference between speed and speed/endurance: just off the podium on Tuesday, add 20 miles and earn the top step on Sunday.

Frank put it simply: he knew he had a 4:45 mile surge in him for the marathon that nobody else had. He knew because he’d run that 10000m final. So at 15K he threw the move, broke free, and on the winding Munich course got away, earned gold, and unknowingly began the boom.

Fifty years later, the past and present tied together again, from reminiscing at Falmouth to watching Ethiopia’s Yomif Kejelcha run 56:51 in Buenos Aires one week later, history’s first ratifiable sub-57 half marathon. In 1972 you could win an Olympic marathon with one surge. Now the whole race is the surge.

Money and technology have become the modern discriminators.

When open prize money hit the roads in the 1980s the global talent pool followed. As the roads grew more lucrative, the track 10,000m lost value outside the Olympics. Speed didn’t just influence endurance, it defined it.

Shorter won Munich in 2:12:19. Rodgers became famous in Boston and New York at 2:09:27 and 2:10:10. Their 5000m times —13:26 for Shorter and 13:42 for Rodgers — were fast enough to compete on the track but not fast enough to win. But they could carry enough of it through hard training and savvy racing to excel on the long road.

Until Bikila in Rome 1960, the marathon was endurance for those without finishing speed. That changed when prize money jumped from five figures to six.

Steve Jones showed the old formula at its peak. Chicago 1984: plain Reebok singlet, no watch, sitting in the pack for 20 miles, then closing the final 10K in sub-30 for a 2:08:05 world record,

A year later he reversed tactics, and tried going out fast just to see. 14:18 at 5K, 28:48 at 10K, 61:42 at halfway, riding the ragged edge of 2:05 pace before super shoes were ever imagined. He held on for 2:07:13, one tantalizing second off the Carlos Lopes world record.

And just before the money era fully arrived, Mexico’s Dionicio Ceron became the last great expression of pure endurance success, three straight London Marathon wins from 1994 to 1996, grinding out 2:08s without a track pedigree, without super shoes, without the accelerants to come. That was endurance racing.

Before the roads created their own specialists the fastest marathoners were track record men taking what speed remained up in distance. Paul Tergat, world records at 5000 and 10,000m, ran 2:04:55 in Berlin in 2003. Haile Gebrselassie, two Olympic 10000m golds and 3:33 for 1500m, lowered it to 2:04:26 in 2007 and 2:03:59 in 2008.

But even before Tergat and Haile, Ethiopia’s Belayneh Dinsamo set a world record that lasted ten years, 2:06:50 in Rotterdam in 1988, without track speed, without the modern marathon economy, without any of the later accelerants. He was the last world record holder built entirely on endurance rather than speed.

The others were track champions first. He was an endurance man. Together they marked the transition. Then came a generation with no track pedigree at all: Patrick Makau at 2:03:38, Geoffrey Mutai with Boston and New York course records, Wilson Kipsang at 2:03:23, Dennis Kimetto at 2:02:57. None had a memorable 1500, 5000, or even 10,000 times. They never bothered with the track.

But before all of them stood Khalid Khannouchi, the prototype of the modern marathon specialist. The immigrant from Morocco had no elite 1500m or 5000m background, yet he broke the world record twice, 2:05:42 in Chicago in 1999 and 2:05:38 in London in 2002. He trained like a marathoner before marathon specific training became the norm. He would do speed work after his 20 miler because he knew he would need speed after fatigue set in. He was the precursor. Makau, Mutai, Kipsang, and Kimetto were the wave.

They professionalized 26.2 because that’s where the money had moved. For a few years pure road endurance, not borrowed track speed, held the world record. A Diamond League 10K paid a few thousand. A marathon major paid $150K plus appearance fees and bonuses. The marathon became a job you chose, not an event you graduated into.

Then speed reclaimed the record and never let go. Eliud Kipchoge, an Olympic 5000m medalist before ever running 26.2, took the world record in 2018 and held it for most of a decade. Keninise Bekele ran 2:01:41 in 2019, three seconds off Kipchoge. The pure marathon interlude was over. Top marathoners’ 1500m PBs dropped from 3:45 to 3:32. Endurance became speed carried longer.

World Athletics dropped the 10000m from the Diamond League in 2020. The sub-27 men lost their stage, their TV time, their contract leverage. If you were East African and this was how you built a house for your parents you followed the money.

The trend sharpened: Sabastian Sawe under two hours in London this spring, Kejelcha running 56:51 for a half marathon. The bridge generation’s lesson, that pure endurance alone could hold a world record, turned out to be a five-year exception, not a rule.

Three accelerants turned endurance into speed. One, Super shoes extended the fast twitch burn rate. Two, Sodium bicarbonate plus fueling buffered acidity and allowed 100 to 120 grams of carbs per hour. Three, double threshold training spread through altitude camps. Result: 56:51 is 95 percent of marathon pace.

For Jones a half at world record effort would have been 105 percent of his marathon pace. That is why Kejelcha dances rather than collapses. Same distance, different sport.

True endurance today lies in the ultramarathons. But because there is no real money in it, the speed men haven’t arrived. UTMB pays €10,000. Western States hands you a belt buckle. A marathon major pays $150K plus appearance fees and bonuses.

The documentary Learning to Fly followed Jim Walmsley through Western States and UTMB. It was beautifully presented and generated buzz. But it had no African influx, no wave of sub-27 track men trading the roads for the mountain paths.

My guess is: as with the roads, the moment real money shows up in the ultras, the speed boys will arrive and transform that, too. Not if, when.

Endurance has always been a moving target. A sub-four mile was once thought fatal. The first marathon ended with the Greek messenger’s mythic death.

Today, women already win outright at 100-plus miles. Courtney Dauwalter – 2017 Moab 240 miler – First overall outright. Jasmin Paris at Barkley. If we keep extending distance to find true endurance does the far end become a women’s sport? Maybe.

And maybe endurance was never about who could run a fast 1500m the longest. Maybe it will come down to who can keep going when speed itself loses value. One day being tough for six ten fifteen hours will pay.

But the problem with using speed as our discriminator rather than competition is that once all the recognizable barriers have fallen, and there’s no shiny object the public can easily comprehend, where do you go?

The official sub-two-hour marathon in London crackled because it broke a definable barrier. But 1:59:30 won’t hold the public’s imagination and 1:58:57 will be indecipherable — like a license plate with a lot of 3s, Bs, and 8s.

We’ve trapped ourselves in a time addiction loop. So we move up the distance ladder again and again looking for new territory to conquer with speed.

Until money shows up where endurance still lives, we’ll keep mistaking velocity for durability and watching each enduring mark wilt like yesterday’s lettuce.

Wonder what they’ll be wistful about at the 50th Falmouth Walk?
