Welcome back to Endurance Capital. Most great careers can be explained by a system. Someone is spotted young, put into a programme, given coaches, funding and supervisors, and if they hold up, they arrive. Neither of the guests in this episode was selected. Anne Haug taught herself to swim at twenty and chose short-course triathlon, the format where the swim decides everything. She finished eleventh at the London 2012 Olympics, became world champion with Germany in the mixed relay, and in 2019 won the Ironman World Championship in Kona in 8:40:10, the first German woman to do it. In July 2024, at Challenge Roth, aged 41, she went 8:02:38, the fastest full-distance time recorded by a woman, after entering the Monday before. Twelve months later she retired. Nina Horowitz was rejected by every PhD programme she applied to. She reapplied, got into Stanford two years later, and now runs ImmuneBridge, a company in cell therapy manufacturing. This is a conversation about the dream Anne chased for a decade and did not get, the title she won in a discipline she says she hated, the fear she carried into every swim start, and the day her will broke. And about what talent systems keep missing.
