Proctor Breaks Decades-Old Canadian U23 300m Record
Albuquerque, N.M. | Dr. Martin Luther King Jr. Invitational
Edmonton sprinter sets national mark and school record in New Mexico
MileSplit BC celebrates Canadian athletes wherever they compete, and this weekend Edmonton's Dianna Proctor gave us a performance impossible to ignore.
Proctor ran 37.05 in the women's 300m at the Dr. Martin Luther King Jr. Invitational in Albuquerque, breaking a Canadian U23 record that had stood for 43 years. The mark was previously set by the legendary Angela Bailey. Her run also reset the University of Guelph school record, eclipsing a mark once held by Olympian Zoe Sherar and is within 0.11 of the Canadian record.
Proctor's rise has been rapid. She announced herself in 2024, sprinting to three personal bests in two days at the World Athletics U20 Championships, winning a silver medal in the 400m while also performing strongly in the 200m and 4x100m relay. By 2025, she was U Sports Rookie of the Year, capturing the 300m national title and improving her Canadian U23 mark to 37.68, the fifth-fastest ever.
Her international resume expanded further last summer. At the 2025 Junior Pan American Games in Paraguay, she won the 400m in a championship record 51.97 and anchored Canada's women's 4x400m relay to gold. She capped the year by making her World Championships debut in Tokyo, running 51.98 in the 400m heats and gaining invaluable experience against the best in the world.
Proctor isn't just moving up through the ranks; she is rewriting the standards of Canadian sprinting. With each race, she's showing that the future of Canadian track is already here, and it's fast, fearless, and unstoppable.
