Haile Gebrselassie

Gebrselassie is the template for the full journey. Two Olympic 10,000m golds and four world titles on the track came from a short, rapid stride and a devastating kick; when he moved up, that same economy let him hold record pace alone. He set world bests from 10km to the marathon, including the first sub-2:04 in Berlin in 2008. The one thing that did not transfer was championship success: his marathon career was all about the clock.
