Canadian international Dayna Pidhoresky will return to the scene of arguably her greatest triumph on October 19, lining up at the TCS Toronto Waterfront Marathon.

It was at this World Athletics Elite Label Race in 2019 that the long-time Vancouver resident cemented her place on Canada’s Tokyo Olympic team by winning the Canadian Championship—and with it, an automatic berth. That performance also produced a personal best of 2:29:03, a time that still ranks her as the 9th fastest Canadian woman in history.

Now 38, Pidhoresky will be contesting Toronto for the fourth time, with this year’s edition once again serving as the Canadian Marathon Championship.

“I know it’s pretty fast based on having run my two fastest times there,” she says of her eagerness to return. “And just being a Canadian championship is a huge draw. There’s a little more incentive than lining up in Chicago or somewhere like that.

“That, I think, as well as being in Canada, it’s a little bit easier to get to than traveling far. All those things keep me coming back. It’s hard to race somewhere else in the fall, I think.

Pidhoresky has represented Canada on the world stage before, competing at the 2017 World Championships in London. Her Olympic journey, however, was far from ideal. On her flight to Tokyo, she was seated near a passenger who later tested positive for Covid. Instead of experiencing the joys of being an Olympian, she was forced into a 14-day quarantine—hardly ideal preparation for the biggest race of her life. On race day, she struggled and finished last.

Since then, she has proven her resilience, bouncing back to win the Vancouver Marathon in 2023 and again in 2025. Adding another Canadian title would be a meaningful milestone.

“My [national] championships wins are so spaced out from each other,” she explains. “I think 2011 was my first Canadian championship at 10K, then the marathon in 2019. So, if I could take another one in 2025, that would really show the span of my career.”

Staying healthy has always been one of her greatest challenges. Together with her husband and coach, Josh Seifarth, she has adjusted her training to improve consistency.

“I definitely cross-train a lot more,” Pidhoresky says. “That’s something I’ve done the last couple of years—trying to find the right balance between cross-training and running.

“In the past I might have run north of 170 km per week or had many weeks at 160 km. Now, although I might be fine doing that, I think it’s a little safer to keep it in the 130–140 km range during a marathon buildup and then supplement that with cycling.”

Six years after her personal best, Pidhoresky believes her best races are still ahead.

“Yeah, I think so for sure!” she declares. “That’s the frustrating part, and maybe why I keep at it. I think if I wasn’t working out well or not racing to my ability, it would be easy to throw in the towel.

“But I know I can still have my best results—I know that for sure. It’s just whether it comes together on race day. That’s racing (laughs). But that’s what keeps me coming back from injuries, because I know my best days are ahead of me.”

Pidhoresky also draws inspiration from fellow Canadians. National record holder Natasha Wodak, an occasional training partner, continues to race strongly at age 43. Malindi Elmore represented Canada at the Paris Olympics last year at age 44. For Pidhoresky, it’s clear: elite athletes are enjoying longer careers than ever before.
