South African runner Sibusiso Kubheka has broken the six-hour barrier in 100 kilometers at the Chasing100 event in Nardo, Italy.

The South African became the first person to complete a 100km run in under six hours, with a time of 5:59:20 at the Nardò Ring auto-racing track in southern Italy.

Kubheka beat the record of the previous fastest time of 06:05:35 run by Lithuania’s Aleksandr Sorokin to write his name in the history books.

Meanwhile, Charlie Lawrence and Aleksandr Sorokin both beat the current record, with Lawrence finish with a time of 6:03:47 and Sorokin beating his record with a time of 6:04:10.

“I’m so proud of my performance out there today,” Kubheka said after breaking the record.

“Breaking this record and becoming the first person to run 100km in under 6 hours was not easy – but thanks to adidas’ partnership, belief and bespoke technologies, we made it happen.

“When we combine the best athletes, the right preparation and sports Innovation, anything is possible.”
