From Rich Froning and Annie Thorisdottir to Mat Fraser and Tia-Clair Toomey, each new generation of champions can see farther because they stand on the shoulders of giants. Fraser's announcement that he would stop competing after the 2020 season made way for a new group of competitors. In 2021, the 15th year of the Games, new and experienced competitors took part in 15 events designed to test the limits of human ability and see who deserves to be called the fittest. Even though there were surprises, upsets, and unbelievable displays of unmatched athleticism, Toomey kept going like a clock in a storm, breaking records and securing her place as the most unbeatable athlete in the history of the CrossFit Games. At the 2021 Games, we saw the return of some of the best athletes ever and the rise of newcomers who will be the Fittest on Earth for the next generation.
