On any given race weekend, riders line up to be measured. They pit themselves and their machines against all comers, borne by an unwavering belief in their own ability to overcome their adversaries and the limitations of the equipment they have been given. They stand to be measured every time they line up. Sometimes, though, the measurement goes deeper. For there are some days when a racer has to step up and go beyond himself, beyond the limitations of his body and his machine, and reach a higher plane.
