The event is decomposed into 16 routes elements, each route takes the rider from one control checkpoint to the next. This speeds up the GPS's auto-routing calculations, makes course navigation more flexible, and facilitates GPS units that limit the number of vias that can be used on a route. Upon arriving at a checkpoint the rider simply selects the next route to navigate to the subsequent control.
NOTE: this is the final version suitable navigating PBP. It was created by South Florida randonneur John Preston with the information available on http://rusa.org/pbp.html and cue sheet shown on the official PHP site. Note that Control 15 is at Dreux (Contrôle - PALAIS DES SPORTS, at 1163km) not Nogent-le-Roi as in previous events.
