Prof. Gavin Kilduff's research on the benefits of rivalry is featured
— May 1, 2015
Excerpt from Outside Magazine -- "Kilduff pored over six years of race data from a U.S. running club. After identifying pairs of rivals, he studied their results. The effect of racing a rival showed improvement by as much as five seconds per kilometre. That’s enough to shave 50 seconds off your next 10K."
