The 2021 World Triathlon Championship Series was the 13th season of the World Triathlon Championship Series, the top level international series for triathlon, since its establishment in 2009. The season consisted of four pairs of triathlon races for both a men's and women's competition, beginning on May 15 in Yokohama, and concluding on August 21 with the grand final in Edmonton. The series calendar also included the 2020 Summer Olympics individual races on July 26 and 27 and mixed relay event on July 31.[1][2]
Vincent Luis and Georgia Taylor-Brown began the season as defending champions from the 2020 season. Less than a month after their victories at the Olympics, Kristian Blummenfelt and Flora Duffy were crowned the series champions, becoming the first athletes to earn Olympic gold medals and World Triathlon Championship titles within the same year.
