Seth Rider

Seth Rider hit a new high in his career as he picked up an Olympic silver medal for the USA at the mixed team relay in Paris.

Rider, who comes from Tennessee, followed in the footsteps of his two older brothers by starting life in the pool as a swimmer. However, that didn’t last too long and he raced his first triathlon aged just six. It remained a hobby growing up until he reached 14, where, realising he had some serious talent, he fully committed to the sport and made a big impact at youth level.

In 2014, Seth raced in the ITU Junior World Championship and then the Youth Olympics in Nanjing, China, where he finished 12th in the individual event and anchored a Team America Mixed Relay quartet to sixth. A year later he was crowned USA Triathlon Junior Champion. 

By 2018, Seth was making his way at elite level and picked up a bronze at the Clermont CAMTRI Sprint Triathlon American Cup, before finishing third at the ITU Under-23 Mixed Relay World Championship in 2019.

Seth Rider’s made his supertri debut in 2021, when, despite a late entry, he was able to pick up a bonus $20,000 for winning the green cycling jersey. 

Now an established short course triathlete approaching his peak, the raw speed means he’s rarely far off the pace in the swim and has seen him become a decorated member of Team USA’s Mixed Relay squad. 

He returned to supertri racing in 2023 where he finished eighth in London, twelfth in Toulouse and tenth in NEOM. 

In 2024 Rider went to the Olympics in Paris and finished an impressive eighth ahead of his US compatriot Morgan Pearson who had recently won a World Series race in Yokohama, and then collected the silver in a team alongside Pearson in the mixed relay.
