Gilbert message appears to be more of a personal thing rather than a general representation of the riders views.thehog said:
Reducing the number of races in the world tour may be required but then the riders themselves can organize their schedules with focus on particular races.
The more difficult the parcours, the more better it is for viewing. If there are no spectators there will be no races. No races means less money to riders. No hills/Mountains/Cobbles means all to sprinters which would be extremely boring.
Weather is certainly not in control of the organizers. Besides which it is the one thing that makes for spectacular viewing & epic racing. if it is too tough then the choice is simple - abandon like many did in MSR, Giro & Vuelta. If it is hazardous like snow covered roads etc then surely the organizers themselves take the decision to stop racing.
