Background: Paris-Roubaix is a unique and singular race of UCI World Tour. Compared to other “classic races”, the difficulty of the route is increased by the mechanical vibrations encountered during many cobbles sectors. These ones represent ~20% of the total distance to be covered (~250 km). They are classified by the organizers according to their length and the cobble’s characteristics from “easy” (two stars) to “very hard” (five stars). Previous studies measured vibration exposure at cyclist’s hand on one single cobbles sector [1] and for whole body on short urban road path [2]. Thus, the vibration exposure of cyclists during a whole race that includes many cobbles sectors remain unknown.
