In 1910, the Primavera gained eternal fame and a place in cycling legend because of the extreme weather conditions. Riders needed to take refuge in the houses along the roads because a severe snowstorm scourged the peloton. Just four out of 63 riders finished the race.
The 2013 edition of Milano-Sanremo was affected by abysmal weather conditions from start to finish. Heavy snowfall and below-zero temperatures forced organizers to shorten the race by 52 kilometres, eliminating the climbs of the Passo del Turchino and Le Manie, and arranging a bus transfer for the race to begin a second time in Cogoleto.
