Edmonton's Dianna Proctor shattered a 43-year-old Canadian U23 record in the women's 300m, clocking 37.05 seconds at the Dr. Martin Luther King Jr. Invitational in Albuquerque, N.M. The performance also established a new school record for the University of Guelph. Proctor continues her rapid rise in sprinting with this latest achievement.
Dianna Proctor, a 20-year-old sprinter from Edmonton, demonstrated her growing prowess over the weekend at the Dr. Martin Luther King Jr. Invitational. Her time of 37.05 seconds in the women's 300m not only surpassed the University of Guelph's previous record set by Olympian Zoe Sherar but also eclipsed the Canadian U23 all-time mark of 37.10, held by legendary sprinter Angela Bailey since 1983.
Proctor's trajectory has been meteoric since 2024. At the World Athletics U20 Championships that year, she achieved three personal bests over two days and secured a silver medal in the 400m. In 2025, as a first-year university athlete, she was named U Sports rookie of the year and won the national 300m title with a then-personal best of 37.68, ranking as the fifth-fastest Canadian U23 time ever.
Her international successes continued into 2025. At the Junior Pan American Games in Asunción, Paraguay, Proctor claimed gold in the 400m with a championship record of 51.97 at La Nueva Olla Stadium. Later that September, she debuted at the World Championships in Tokyo, running 51.98 in the 400m heats. Athletics Canada captured the moment, stating, “Stepping onto the world stage is just the beginning—the best is yet to come.”
This latest record underscores Proctor's potential as she builds toward senior-level competition.
