On Your Mark
From this photo the educated eye can clearly discern that Jason means business in the Giro. Grand Tours are seldom won at the team presentations, but they can be lost. A three week stage race is not a thing to take lightly and even the strongest of riders must carefully budget their energies if they hope to excel in the arduous weeks ahead. This is the very highest level of competition and as such heads are shaved and toenails clipped to increase aerodynamics and save weight as any advantage is sought. The most determined and savvy riders will even eschew a seemingly mundane and easy task such as holding up a bike. They know it for what it is, a drain on precious caloric reserves when they are needed most. So too the raising of an arm or even two as part of a publicity stunt. Nay(!) say the serious players, their arms will go up when victory is achieved and not before!
