The purpose of this study was (i) to determine the age of peak triathlon performance for world class athletes competing in Olympic, Half-Ironman and Ironman distance races and (ii) to investigate a potential change in the age of the annual fastest athletes across years. Data of ages and race times of all finishers in the international top races over the three distances between 2003 and 2013 wer...

To confront the issue that the selection of the host city is endogenous, we use a natural counterfactual: countries whose cities also bid for the Ol...
