The participation in triathlons among U.S. Americans declined steadily between the mid-2010s and 2024, amounting to 3.1 million in 2024. At its peak, the U.S. participation in triathlons surpassed 4.2 million people. After setting a record of 1.88 million participants in 2017, the number of non-traditional and off-road triathlon racers decreased, with the figure amounting to 1.37 million in 2024.
Different styles of the sport
Enthusiasts of this sport can either take part in a conventional triathlon or an off-road triathlon. The conventional triathlon includes swimming, running, and cycling over various distances. Off-road triathlons differ from traditional forms in that the sites for running and cycling are generally unpaved and mountainous. In the United States, the conventional triathlon is, perhaps unsurprisingly, the more participated-in style of the sport.
