With the 2023 IAU 24-Hour World Championships simply days away, beginning this Friday, December 1, in Taipei, we’re wanting again on the 140-plus-year historical past of the 24-hour world document and its development to this weekend’s beginning line. The present 24-hour world document holders, Alexander Sorokin and Camille Herron, are planning to race, and we’ll be searching for challenges from them and others to the present document marks.

Ultrarunning has its roots in what’s known as pedestrianism, the game of overlaying very lengthy distances over lengthy intervals of time by strolling and operating, which emerged the late seventeenth century in England. Amongst their many occasions, the pedestrians took half in staged indoor six-day races, mixing strolling and operating to cowl huge distances.

The primary credible recorded 24-hour end was by one of many nice pedestrians of the late nineteenth century, Charles Rowell, at one such occasion. Rowell is credited with overlaying over 530 miles in a single such six-day race. In a six-day race in 1882, he’s credited with overlaying 150 miles within the first 24 hours of the occasion — the primary time 150 miles (241 kilometers) was damaged.

It might be nearly 100 extra years earlier than we might have a ratifiable girls’s document. Though there have been anecdotal reviews of a feminine runner finishing 106 miles in a 24-hour occasion within the distant previous, the primary recorded distance on the DUV Extremely Marathon Statistics web site is by the American Marcy Schwam. She ran in the 1979 David Copperfield 48-Hour Observe Ultramarathon in Woodside, California, and recorded 113.671 miles (182.937 kilometers). This appears to be the primary recorded and ratified feminine 24-hour world document of contemporary instances.

Within the years that adopted, each information have been steadily improved upon as new generations of athletes push the boundaries of what’s doable. Within the steadiness of this text, we’ll dive deep into the development of the 24-hour world document from these beginning factors.

The Historical past and Evolution of the Males’s 24-Hour World Report

Fifty Years Later

Now we have to go ahead to 1931, when the legendary Arthur Newton of England achieved a distance of 152.306 miles (245.113k). The five-time Comrades Marathon winner ran that on an indoor monitor in Ontario, Canada.

Wally Haywood, 1953 

Quick ahead one other 20 years to 1953, and Newton was instrumental with the U.Ok. Roadrunners Membership in staging a 24-hour race on the Motspur Park cinder monitor in Surrey, England. South African Wally Hayward, one other multiple-time Comrades Marathon winner, grew to become the primary runner to interrupt the 250k barrier, operating 159.319 miles (256.4k).

Ron Bentley, 1973

The U.Ok. Roadrunners Membership organized a number of 100-mile and 24-hour monitor races all through this time. In 1973, Ron Bentley from the well-known Tipton Harriers membership ran 161.309 miles (259.603k), simply lacking 260k, however going by means of the imperial 160-mile mark for the primary time. Like Hayward’s document, this was run on a cinder monitor at Walton-on-Thames, England.

Park Barner, 1979

By way of the late Nineteen Seventies and early Nineteen Eighties,  a resurgence of 100-mile and 24-hour races happened. The U.Ok. nonetheless had annual occasions, however now these had been being replicated in Europe and the U.S. Beforehand, the document had been damaged with lengthy gaps of usually 20 years between them. Over the subsequent three years, the document would fall on 5 events.

America was the venue for the subsequent enchancment in 1979. American Park Barner was some of the distinguished American ultrarunners of the time and, like many of the earlier record-breakers, simply beloved operating. Their refreshing angle is greatest summed up in Barner’s remark in a single interview: “I nonetheless don’t really feel like I’m primary. I really feel the identical approach I did after I began operating significantly in 1968. I attempt to not let something have an effect on me. I don’t want trophies or wine or something. It’s one thing I get pleasure from doing. It makes me really feel good. I really feel like a child.”

Barner ran 162.304 miles (261.204k), rising the document by a mile.

The French Connection and A Report-Breaking Brit

It was again to Europe, and an rising French ultrarunner, Jean-Gilles Boussiquet, improved the document twice within the area of eight months. Blackburn within the north of England was the venue for an occasion in October 1980, the place the Frenchman pushed the document out to 164.109 miles (264.108k).

Clearly attending to grips with the pains of the occasion, the next Could, in 1981, he took up the problem once more. In an occasion in Lausanne, Switzerland, he added an extra 8k (5 miles) to grow to be the primary runner break the 270k barrier. He completed with 169.400 miles (272.624k).

Now, these 24-hour races had been spreading. Within the west of England, the native Gloucester Athletic Membership had a gaggle of very competent ultrarunners. Driving the wave, they organized an occasion at their native monitor in 1982. A number of of them took half. Englishman Martin Daykin, one of many high European 100k runners of the time, was the favourite. Nevertheless it was his compatriot Dave Dowdle who prevailed and broke 170 miles for the primary time, recording 170.553 miles (274.480k), a distance which till just lately was the British document.

Dowdle’s world document glory was solely to final till the autumn that yr, when the document returned to France. In November 1982, Bernard Gaudin broke it by a whisker, including an extra 143 meters to complete with 170.699 miles (274.715k).

The Yiannis Kouros Period

In 1983, an unknown Greek runner, Yiannis Kouros, astounded the extremely world by emphatically successful the well-known Spartathlon race. A feat he repeated the next yr, 1984, when overlaying the 245k course in a document 20 hours and 25 minutes. The course in Greece contains mountainous sections, and temperatures might be heat. Hypothesis began amongst ultramarines on what Kouros might obtain in a flat 24-hour race.

They didn’t have to attend lengthy. Simply eight weeks later, in November 1984, he was on the beginning line in New York, U.S., for the Sri Chinmoy 24-Hour Race. The remaining is extremely historical past. He improved the prevailing document by over 10k, taking it to 176.999 miles (284.583k).

Over the subsequent few years, he would go on to document 14 of the very best males’s 24-hour instances ever and break the world document on an extra 4 events, pushing it as much as the primary 300k effort with 188.589 miles (303.506k) in 1997.

Kouros had made the 24-hour distance his personal, and plenty of felt the 303k would final for a few years. Over the subsequent 20 years, solely a few runners would document over 280k, however nobody neared 300k.

Alongside Comes Alexander Sorokin

From 2015, when he ran his first 24-hour occasion in Turin, Italy, and recorded 150.489 miles (242.189k), Alexander Sorokin elevated his private document incrementally till recording 173.345 miles (278.972k) in successful the 2019 IAU 24-Hour World Championships in Albi, France.

Two years later, in August 2021, he took half within the UltraPark Weekend 24 Hour race in Pabianice, Poland. He improved his personal private greatest by an enormous 30k (18 miles), to take Kouros’s males’s 24-hour world document. He improved it by 6k to document 192.251 miles (309.399k). It was an enormous soar, not solely on his personal development, but in addition comfortably surpassing Kouros’s mark.

Not content material to sit down on his laurels, one other yr later on the 2022 IAU 24-Hour European Championships, he elevated this by an extra 10k to 198.598 miles (319.614k), narrowly lacking the 200-mile barrier.

As talked about, Sorokin will race this weekend’s 2023 IAU 24-Hour World Championships, so we’ll see if that elusive 200-mile barrier is approached.

The Historical past and Evolution of the Ladies’s 24-Hour World Report

The Battle of the Brits 

Quick ahead three years from Marcy Schwam’s 1979 24-hour world document run, and the British took over for some time. In 1982 — on the identical race at Gloucester, England, the place Dave Dowdle set the then males’s 24-hour world document — Britain’s Lynn Fitzgerald set a girls’s 24-hour world document and pushed it up over 200k to 133.533 miles (214.902k).

Three years later, in 1985, the legend that’s the extremely pioneer and a number of world document breaker Eleanor Adams-Robinson made one other breakthrough. After exhibiting promise in two earlier 24-hour races, she beat Fitzgerald’s distance with 138.441 miles (222.800k). That race was held at Nottingham, England, and was the beginning of a four-year relationship the place she and Hilary Walker, the opposite nice English extremely pioneer, traded the 24-hour world document on 5 events. On the finish of this battle, at a race in Australia in 1989, Adams-Robinson pushed the document up her third and ultimate time to 149.234 miles (240.169k).

Adams-Robinson and Walker had each spoken of wishing to be the primary woman to run over 150 miles in 24 hours. Adams-Robinson bought shut on this event, however was round three laps of a 400-meter monitor brief. Ultimately, neither of them made that breakthrough.

The 150-Mile Breakthrough

The German runner Sigrid Lomsky, at 50 years younger, broke that 150-mile mark by recording 151.401 miles (243.657k).

This mark stood for 3 years earlier than it was damaged by the younger Russian Elena Sidorenkova, who ran 154.659 miles (248.901k). That distance wouldn’t be surpassed for over 13 years.

Japanese Masterclass

The Japanese had for a very long time been very competent 100k runners. They had been now turning their consideration to 24 hours.

In 2009, Mami Kudo cracked the 250k barrier, recording 158.092 miles (254.425k) at a race in Taipei. Two years later, on the identical race, she was to push it out much more, including a couple of kilometer to document 158.637 miles (255.303k). She was now 47 years previous.

A Polish Double in 2017

Kudo’s document stood for nearly six years, till 2017, which needs to be considered the yr of the Polish double. This was the yr that Patrycja Bereznowska, of Poland, broke the 24-hour world document twice in 12 weeks.

Firstly, in April 2017, she ran 159.223 miles (256.246k), surpassing Kudo’s mark by a couple of kilometer. The 160-mile barrier approached, however few, besides maybe Bereznowska herself, thought that it will occur so quickly. Simply 12 weeks later, in July 2017, she competed on the IAU 24-Hour World Championships occasion in Belfast, Northern Eire.

The occasion is greatest remembered for the facility failing and plunging the entire race into darkness, as assist crews hurried to search out head torches within the pitch darkness whereas hoping the chip timing system was nonetheless recording, with its built-in backup batteries, as most runners weren’t going to cease. Energy was duly restored, and so was the reside timing, to the reduction of everybody.

After holding off the early tempo of different runners, Berezknowska maintained her personal regular progress to complete strongly within the ultimate hours, operating simply over 4k additional with 161.550 miles (259.991k). She set a brand new landmark for ladies, operating over 160 miles in 24 hours.

Right here Comes Camille Herron

It didn’t take lengthy earlier than the U.S.’s Camille Herron determined to have an actual crack on the 24-hour occasion. The a number of document holder at most distances from 50 miles to 100 miles ran 162.918 miles (262.192k) on the monitor, in Phoenix Arizona, in December 2018.

She definitely wasn’t postpone by the expertise, as just below a yr later — on October 27, 2019 — she went even additional on the IAU 24-Hour World Championships at Albi, France. This time on a street loop, she elevated the gap by nearly 5 miles to 167.842 miles (270.116k).

This mark has held agency for 4 years. Herron, like Aleksandr Sorokin, is entered for this weekend’s 2023 IAU 24-hour Championships in Taipei. Time will inform if both document will probably be threatened within the warmth and humidity of that area.
