Josh began coaching athletes in 2010 starting with his wife (girlfriend at the time) Dayna Pidhoresky. Over the past decade he has coached athletes across distance running and triathlon, focusing on methodical training progression to achieve the best possible individual performance on race day. In 2013 he and Dayna moved from Windsor to Vancouver, away from friends and family, chasing a more favourable training environment through Canadian winters.

Josh has a Bachelor’s degree in Human Kinetics (Movement Science – 2011) and a Master’s degree in Human Kinetics (Applied Human Performance – 2013).

Favourite race distance and why?

Half-marathon and Ironman 70.3. The distances are long enough that an athlete isn’t just limited by pure fitness, but also by the decisions they make within the race in terms of pacing, nutrition and tactics.

Most memorable coaching moment?

Being at the finish line of the Canadian Olympic Marathon Trials in Toronto in 2019 to see my wife win the event under the Olympic standard. This secured her spot on her first Olympic team and was the culmination of a decade of work and sacrifice.

Favourite post-workout treat or go-to place?

Cartems donuts!
