Growing up in Humboldt, Brianne Theisen-Eaton was a talented multi-sport athlete. The breadth of her athleticism led her to the heptathlon and eventually an Olympic medal podium.
She won 16 individual high school track and field medals over her four years, setting a new standard of excellence. She drew the attention of the Saskatoon Track & Field Club and made the commute to train there starting in Grade 10. It was her coaches there that convinced her to try the heptathlon – a seven-event, two-day grind. Theisen-Eaton completed her first heptathlon and vowed to never do it again, until she was told that she had just met the qualifying standard to represent Canada at the World Youth Games.
She attended the University of Oregon and joined a program full of future Olympians – including her future husband, Olympic gold medalist Ashton Eaton. During her legendary career at Oregon, Theisen-Eaton became the fourth woman to win seven National Collegiate Athletic Association (NCAA) national titles, and she graduated holding five school records. She also set the NCAA and Canadian pentathlon record – a five-event competition held during the indoor season.
Theisen-Eaton competed at the International Amateur Athletics Federation (IAAF) World Championships in 2009. She attended the 2012 London Olympics, finishing 11th in the heptathlon. She had her international breakthrough in 2013 at the IAAF World Championships in Moscow, where she finished second. In 2014, she finished second in the pentathlon at the World Indoor Championships and won a gold medal in the heptathlon at the Commonwealth Games in Glasgow, Scotland.
In 2015, she finished second at the IAAF World Championships in the pentathlon and won the indoor world title in Portland in the pentathlon.
Theisen-Eaton won a bronze medal at the 2016 Olympic Games in Rio de Janeiro, Brazil. She sat in sixth place after the first day’s competition but put together a great second day to storm back and earn a bronze medal. She retired from competition after the Olympics.
At the time of her induction, Theisen-Eaton held the Canadian records for most points (6,808) in the heptathlon and the most points (4,768) in the indoor pentathlon.
Installed in the Saskatchewan Sports Hall of Fame on September 26, 2026.
