Then, at 10:15 am, the “Totor à Vélo” sculpture will be unveiled, as well as the new developments around the cycle path in the presence of the artist Bolongaro. Stéphane Bolongaro, alias "Totor" from the name of his last and already very famous creation is a Nice artist who made a career following the example of two geniuses from the Nice school: Arman and Sosno. It was in 2015 that Totor the dog was born. As part of the Grand Départ, he made a polyester sculpture of Totor on a bicycle. This is visible from the road as well as from the cycle path.
