Guest: Toronto Star reporter Kerry Gillespie

The interview today is timed to run 17 minutes and 28 seconds, the exact length of Stouffville 12-year-old Sawyer Nicholson's world-record-breaking 5-kilometer run. So listeners are invited to jog along as they listen and see how their own progress stacks up. Star reporter Kerry Gillespie talks about the tiny running phenomenon, and how she took up running as training for another sport, how she developed, and the blowback her family has gotten online as a result. And Sawyer herself checks in with us from checkpoints on her own 5K training run. PLUS: the world-record holder's pump-up playlist.

This episode was produced by Julia De Laurentiis Johnston, Edward Keenan and Sean Pattendon.
