Ethiopia’s Yomif Kejelcha produced one of the most extraordinary performances in road racing history on the streets of Buenos Aires, Argentina, reclaiming the half marathon world record with a sensational 56:51 performance at the 2026 Buenos Aires Half Marathon.

The former world record-holder delivered a breathtaking exhibition of speed and endurance to take 29 seconds off the previous pending mark of 57:20, set by Uganda’s Jacob Kiplimo and takes a huge chunk from his own former official world record. Kejelcha's new performance is pending the standard ratification procedures, but if officially ratified, it will return the world record to the Ethiopian star and mark another remarkable chapter in the evolution of the event. 

Kejelcha's achievement is particularly significant because the 57-minute barrier had already been broken before. Jacob Kiplimo had previously run under 57 minutes, clocking 56:42 that was not ratified demonstrating that the once-unthinkable barrier was possible. Kejelcha, however, has become the second man to run under 57-minute barrier who now returns to the top of the all-time rankings with another historic performance in Buenos Aires.

The Ethiopian's race was remarkable not only for the final time but also for the way he built his performance. He covered the opening five kilometres in 13:44 before reaching 10km in 27:18. Rather than slowing, Kejelcha accelerated through the middle stages, passing 15km in 40:39 and 20km in 54:02 as he continued to push the limits of elite road racing.

By the time he reached the finish line, Kejelcha had completed the race at an extraordinary average pace of approximately 2:42 per kilometre, producing one of the most astonishing sustained efforts ever witnessed in distance running. His stunning run sent a powerful message to the athletics world and further strengthened his status as one of the most formidable distance runners of his generation.

Behind the record-breaking champion, Ethiopia completed a dominant clean sweep of the men's podium. Tadese Worku Gebresilase claimed second place in 59:18, while Bereket Nega Batebo secured third in 1:00:17, giving Ethiopia a memorable one-two-three finish in the Argentine capital.

Kenya’s Jonathan Kipkoech Kamosong finished fourth in 1:00:20, followed by compatriot Simon Maywa in fifth with 1:00:55. Argentina’s Ignacio Erario gave the home supporters plenty to celebrate with an impressive sixth-place finish in 1:00:57, breaking the one-hour barrier in front of an enthusiastic local crowd.

Dillon Kipyeko of Kenya finished seventh in 1:01:07, with Robert Kiprop Koech eighth in 1:02:01. Mexico’s Julio Ortiz Ponce took ninth place in 1:03:17, while Colombia’s Jimmy Gómez completed the top 10 in 1:03:34.

The Buenos Aires Half Marathon will now take its place in the history books as the scene of a truly extraordinary breakthrough. For Kejelcha, this was more than just another victory. It was a spectacular return to the top, reclaiming a world record he had previously held and once again rewriting the limits of the half marathon.

The 56:51 performance remains pending ratification, but Yomif Kejelcha's run has already delivered one of the defining moments in the history of road racing.

Kenya’s Alexander Mutiso Munyao set a men’s course record and Dolphine Nyaboke Omare claimed a clear women’s race win at the Gifu Half Marathon, a World Athletics Elite Label road race, in Japan on Sunday (24).

In a close finish, Munyao clocked 59:56 to win by just seconds ahead of his compatriot Benard Kibet (59:57) and Emmanuel Moi Maru (59:58).

Omare, meanwhile, ran 1:08:13 to win by 47 seconds ahead of Australia’s Sinead Diver, whose 1:09:00 is a world W45 record. Japan’s Haruka Yamaguchi was third in 1:09:50.

In the men’s race, five athletes ­– Munyao, Kibet, Maru, Joseph Karanja and Charles Karanja Kamau – remained together through 15km, which was passed in 42:52. By 20km, reached in 56:51, it was down to just Munyao, Kibet and Maru.

From there, Munyao kicked to victory to lead his compatriots under the course record of 1:00:02 set by Bedan Karoki in 2014 and the one-hour mark.

Karanja was fourth in 1:00:12 and Kamau fifth, 10 seconds behind him.

Omare had built a 31-second lead by 10km in the women’s race, passed in 32:20. Diver was just ahead of the chase group by that point, with her compatriot Eloise Wellings four seconds back from her.

Omare reached 15km in 48:46 and 20km in 1:04:40 before crossing the finish in 1:08:13. Behind Diver and Yamaguchi, Wellings was fourth in 1:10:42, one second ahead of Japan’s Reia Iwade.
