Long before Olympic stadiums, world medals and a 44.31 personal best, Lythe Pillay was just a young boy discovering a love for the track in his first year of primary school.
That early spark has carried him all the way to the world stage and now into a new chapter with Swiss sportswear brand On.
On has announced that Pillay, one of South Africa’s brightest 400m stars, has joined its global athlete roster. The signing is more than a personal milestone for the two-time Olympian. It also marks a meaningful step for the brand, as Pillay becomes the first professional South African athlete to join On’s growing track and field roster.
For Pillay, the journey to this moment has been built on steady progress, resilience and a habit of rising when the stakes are highest. He announced himself to the world in 2022 when he won gold at the World U20 Championships in Cali, Colombia. From there, he continued to build his reputation as one of the sport’s most exciting quarter-milers, earning the honour of representing South Africa at both the Tokyo 2020 and Paris 2024 Olympic Games.
Then came 2025, a season that showed exactly why so many believe Pillay’s best is still ahead of him.
First, he claimed gold at the World University Games, underlining his class as an individual competitor. Then, on one of athletics’ biggest stages, he helped South Africa secure a historic bronze medal in the men’s 4x400m relay at the 2025 World Athletics Championships in Tokyo. It was the kind of season that confirmed what the numbers already suggested: with a personal best of 44.31 seconds, Pillay is not just competing with the world’s best, he is becoming one of them.
That sense of ambition is part of what drew him to On.
“I felt a deep connection with On because we share that same hunger and drive to establish ourselves as household names among the giants of the industry,” said Pillay. “Both the brand and I have a point to prove to the world, and I’m excited to collaborate and channel that collective effort toward reaching the next level of the sport.”
It is a fitting partnership. On’s own rise has been shaped by bold ambition and a willingness to challenge expectations, qualities that echo Pillay’s journey from schoolboy athlete to global medal contender.
“Lythe is an exceptional talent whose ambition and underdog spirit perfectly mirror our own journey,” said Silja Mühlebach, Athlete Manager at On. “His transition from a child falling in love with the track to a world-class medalist shows a level of dedication that we are incredibly proud to support. Welcoming Lythe is a key step in our mission to grow On’s roster of elite sprinters in Africa, and we look forward to seeing him challenge the status quo.”
The partnership also signals something bigger. By bringing Pillay onto its roster, On is making a clear statement about the future, one that includes deeper investment in Africa’s sprinting talent and a stronger presence in one of the sport’s most exciting regions.
And while Pillay’s story is still being written on the track, his vision stretches beyond it. Alongside his athletics career, he is pursuing a BCom in Accounting, building a foundation for life in business and finance once his racing days are done.
For now, though, the focus is firmly on what comes next.
A boy who once fell in love with running has grown into one of South Africa’s most promising athletes. Now, with On behind him, Lythe Pillay steps into his next race carrying not only his own ambition, but the momentum of a partnership built on belief, hunger and the promise of more to come.
