Canadian Runner Shatters National Half-Marathon Record

A young Canadian runner just proved that sometimes five weeks is all you need to rewrite history.

Jadyn Keeler crushed Canada's half-marathon record on Sunday in Copenhagen, finishing in 1:08:03 at the World Athletics Road Running Championships. The 23-year-old from Barrie, Ontario, shaved an incredible one minute and 35 seconds off the previous national record set by Andrea Seccafien in 2020.

Here's what makes this even more remarkable: Keeler only ran her first half-marathon five weeks ago. At the Canadian championships in Edmonton, she won in 1:12:12 despite the course being measured incorrectly, forcing runners to cover an extra 700 meters. Her Copenhagen time was more than four minutes faster.

Keeler placed 16th overall in a competitive international field. Kenya's Agnes Ngetich took gold and set a world record for women-only half marathons with a blistering 1:05:15.

The young Canadian is building quite the resume. She already holds the U23 indoor 5,000-meter record and the U23 10,000-meter record, with her 10K time ranking seventh on Canada's all-time list.

After the race, Keeler told Canadian marathon record holder Natasha Wodak that the experience was electric. "For me it was my first senior national team experience," she said. "Had a great race out there."

The Ripple Effect

Canada's performance in Copenhagen shows the depth of talent emerging across the country's distance running scene. Quebec's Florence Caron ran a personal best 1:11:03, while Élissa Legault clocked 1:11:15, also a personal best. Together with Keeler, they helped Canada finish seventh in the women's team standings.

The weekend also saw Canadian runners set personal bests across multiple events. Sisters Lucia and Gabriela DeBues-Stafford both broke their mile records, finishing eighth and ninth respectively. Several other Canadians posted career-best times in the 5K and mile races.

Keeler's already looking ahead, acknowledging she was "just over the 68-minute mark" but promising to "get it next time."
