How unwavering support fuels SA’s ultra-marathon queen, Gerda Steyn

adidas is excited to announce the release of the first episode of their brand campaign, ‘Plus One Effect’, featuring SA’s ultra-marathon queen, Gerda Steyn and her husband, Duncan.

The six-part series explores the stories of distinguished athletes and the vital role of their ‘Plus Ones’, the supporters who shaped their journeys from the sideline. Their presence changes the game, turning doubt into confidence and pressure into joy.

The power of encouragement

Building on the success of the 2024 ‘You Got This’ launch, the 2025 campaign highlights the power of encouragement, revealing that 4 in 5 athletes face unhelpful sideline behaviour, which can lead them to leave sports.

Rooted in the universal truth that every athlete needs someone in their corner, the campaign highlights how a strong support system can be the difference between success and self-doubt.

Backed by unwavering support

As one of South Africa’s most celebrated long-distance runners, Gerda’s story is deeply rooted in the local running community.

With five consecutive victories at the Two Oceans Marathon, Gerda is ready to chase her sixth, backed by the unwavering support of those who believe in her.

While her determination and training have shaped her success, her story proves that behind every athlete, there’s a ‘Plus One’ cheering them on.

Gerda’s plus one

Gerda’s journey is one of resilience, dedication, and an unshakable belief in what’s possible – one she hasn’t taken alone. At the heart of her success is her husband, Duncan Ross, who has been by her side every step of the way. 

From handling race-day logistics and refining training plans to pacing her runs by cycling alongside her, assisting with nutrition and hydration, and keeping her motivated during the long miles, his support has been instrumental to her journey.

Gerda is celebrated as a three-time Comrades Marathon champion, five-time Two Oceans Marathon winner, course record holder, and two-time Olympian (Marathon – 2021/2024).

Yet, behind her remarkable achievements, Duncan’s invaluable role often goes unnoticed. She attributes much of her success to the constant belief and encouragement from those working behind the scenes, demonstrating that a strong support system drives every record-breaking performance.
