The history of the men’s half marathon world record is a remarkable journey through more than six decades of distance running, tracing the sport’s transformation from club-level competition to an era of extraordinary professional speed.

The story began in the spring of 1960 in Romford, Essex, where British club runner Brian Hill-Cottingham ran 21.0975 kilometres in 1:07:01, setting the fastest officially recorded time at the distance at the time.

For years, the record progressed slowly. British and American runners dominated much of the early history, with improvements often measured in seconds rather than dramatic leaps. Ron Hill lowered the mark to 1:05:44 in 1965, while Derek Clayton took it down to 1:03:22 in 1967. Through the 1970s and 1980s, the barrier continued to fall as athletes from different nations gradually pushed the limits of what was possible over 21.1 kilometres.

Then came the breakthrough that changed the character of the event.

In 1993, Kenya’s Moses Tanui became the first man to break the one-hour barrier, running 59:47 in Milan. It was a landmark moment for road running. The half marathon was no longer simply another distance on the racing calendar; it had become an event worthy of specialised preparation and elite-level ambition.

Kenya subsequently established a remarkable presence in the record progression. Paul Tergat lowered the record to 59:17 in 1998 before eventually pushing it below 59 minutes with a 59:06 mark later that year. Eritrea’s Zersenay Tadese and Kenya’s Sammy Wanjiru continued the progression in the 2000s, with Wanjiru taking the record to 58:33 in 2007.

Tadese reclaimed the record in 2010 with 58:23, but the most dramatic developments were still to come.

In 2018, Kenya’s Abraham Kiptum ran 58:18, only for countryman Geoffrey Kamworor to lower the standard to 58:01 in 2019. A year later, another Kenyan, Kibiwott Kandie, produced one of the greatest breakthroughs in the event’s history, becoming the first man to break 58 minutes with 57:32 in Valencia.

Uganda’s Jacob Kiplimo then entered the record books, running 57:31 in Lisbon in 2021. Ethiopia’s Yomif Kejelcha lowered it by another second to 57:30 in Valencia in 2024.

And then, in 2026, the record progression became a breathtaking battle between two of the finest distance runners of their generation.

Kiplimo reclaimed the world record in Lisbon with 57:20, taking 10 seconds from Kejelcha’s mark. But Kejelcha responded with an extraordinary performance in Buenos Aires on 23 August 2026, stopping the clock at 56:51.

The improvement was staggering—29 seconds faster than Kiplimo’s previous record.

Kejelcha’s 56:51 means he averaged approximately 2:42 per kilometre for the entire 21.0975-kilometre distance, a pace that would have seemed almost unimaginable when Hill-Cottingham first established the record at 1:07:01 in 1960.

From 1:07:01 to 56:51, the progression tells the story of an event that has undergone a remarkable transformation. Training has become more sophisticated, competition has intensified, courses have become faster, and generations of athletes have continued to challenge the boundaries of human endurance and speed.

What began as a record set by a British club runner on a spring day in Essex has evolved into one of the most fiercely contested records in modern distance running.

And with Kiplimo and Kejelcha pushing each other to unprecedented heights, the question is no longer whether the half marathon can go faster.

The question is: how low can the world record ultimately go?
