The capacity to do work is something that defines an Olympian. Not only is physical capacity combined with concentration, but even the daily emotional work of so entirely devoting your life to just one thing.
Or in the case of Canadian track cyclist Zach Bell, two things.
Bell, of Watson Lake, Yukon, has twice won silver medals in the men's Omnium, a discipline that is cycling's equivalent of the decathlon. Competitors test themselves in six events, scoring points in each, which in turn determines the overall result.
Not only must competitors manage the mental and emotional challenges of competing in multiple events, but to succeed, an athlete must be able to do massive amounts of work, at extreme levels of intensity.
Those demands are what cause Bell to leave the track is his preparation to compete in the velodrome at the London 2012 Olympic Games.
