Russ Cox is the man with the data when it comes to Kona and 70.3 Worlds qualification. In this episode we discuss the new qualification system announced by Ironman in July 2025, and the implications for athletes wanting to qualify. HIGHLIGHTS AND KEY TOPICS: A detailed view on the inner workings of the new qualification system work How do the "Kona standard" and "70.3 standard" (coefficients for normalised age-graded times) work? Common misconceptions about the new system Pros and cons of the new qualification system Fairness Are there winners and losers with the new system? Implications of the new system for athletes wanting to qualify for Kona or 70.3 Worlds Can you predict the time needed to qualify? Optimising race selection under the new qualification system DETAILED EPISODE SHOWNOTES: We have detailed shownotes for all of our episodes. The shownotes are basically the podcast episode in written form, that you can read in 5-10 minutes. They are not transcriptions, but they are also not just surface-level overviews. They provide detailed insights and timestamps for each episode, and are great especially for later review, after you've already listened to an episode. Naturally, as great as they are, they do not cover absolutely everything in as great detail as we can do in a 45-90 minute podcast episode.
