Iím an author and journalist in Toronto. My
primary focus these days is the science of endurance and fitness, which I cover
for Outside (where Iím a contributing
editor and write the Sweat Science column), The
Globe and Mail (where I write the Jockology
column), and Canadian Running
magazine. Iíve also covered technology for Popular
Mechanics (where I earned a National Magazine Award for my energy reporting)
and adventure travel for the New York
Times, and was a Runnerís World columnist from 2012 to 2017.

Other Surprising Discoveries from the Science of Exercise, which was published in 2011. I also wrote Big Ideas: 100 Modern Inventions That Have Transformed Our World, in 2009.

nanomechanics. During that time, I competed as a middle- and
long-distance runner for the Canadian national team, mostly as a miler
but also dabbling in cross-country and even a bit of mountain running.
I still run most days, enjoy the rigors of hard training, and
occasionally race. But I hate to think how Iíd do on an undergraduate
