61-year old South African businessman Adrian Gore ran the Boston Marathon and wrote a new book while leading Discovery

The Discovery co-founder and CEO ran both the London and Boston marathons this year, finished writing a new book and continued running one of South Africa's largest financial services groups. He is 61.

His Boston Marathon time was the kind of detail that tells the rest of the story. Gore crossed the finish line in 3 hours, 31 minutes and 16 seconds, a result that placed him in the top half of the field. The performance is impressive at any age. At 61, while leading a company with a market capitalization of over R200 billion, it sits in a different category.

Gore treated the marathon as a deliberate exercise in goal-setting, not a hobby. He has argued for years that goals are more than targets. They are psychological tools.

"A goal doesn't only give you something to aim for. It also gives you something to lose. That's where loss aversion becomes so powerful," Gore said. "Goals are also recursive. One breakthrough resets your definition of what's possible, and the next goal is built on the new standard."

The framework is consistent with how Gore has built Discovery over three decades. He co-founded the company with Barry Swartzberg in 1992 as a medical insurer. Today it operates across health, life, investment, banking and global insurance, with footprints in South Africa, the United Kingdom and Asia. Gore has spoken publicly about the role of discipline, behavioral incentives and long-term thinking in that expansion.

His new book, titled The Four Principles, is scheduled for release on July 30, 2026. Gore said it emerged from a specific question that had taken hold of him.

"I wrote the book because I became obsessed with the question of impact and the question of why some people create extraordinary impact," Gore said.

The timing of the output is what makes the year remarkable. Gore completed both marathons and finished the manuscript during a demanding period for Discovery. The group posted a 24% rise in normalized operating profit to R8.9 billion in its half-year results for the period ending December 2025. Discovery Bank crossed into profitability for the first time during the same window, posting R75 million in normalized operating profit after a R145 million loss in the prior period.

Gore owns a 6.71% stake in Discovery, which trades on the JSE. Forbes estimates his net worth at approximately $500 million, making him one of the most closely watched South African business figures on the Johannesburg Stock Exchange. His recent months suggest the marathon mindset is not separate from the CEO work. It is the same discipline, applied across different tracks.
