Nairo Quintana (Arkea-Samsic) crashed at the top of the Côte de Rimiez but jumped up and got back on his bike quickly.
Other accidents in the streets of the city of Nice saw Ilnur Zakarin (CCC Team), Kevin Ledanois (Akea-Samsic), Domeinco Pozzovivo (NTT Pro Cycling), Caleb Ewan (Lotto Soudal), Giacomo Nizzolo (NTT Pro Cycling) ), Sonny Colbrelli (Bahrain McLaren) and others crash, while Richie Porte (Trek-Segafredo) was also left behind until the peloton relaxed in solidarity.
Luke Rowe of Ineos Grenadiers and George Bennett of the Jumbo-Visma team tried to convince the peloton to ride cautiously in the rain, but others were keen to run.
Veteran Tony Martin (JUmbo-Visma) convinced the peloton to ride carefully by waving his arms. Astana tried to increase the pace only for cyclist Karma to intervene and Miguel Angel Lopez locked his brakes and slowly crashed into a sign post.
The peloton then decided to calm down and go up the final climb and descent together.
