(Currently) doesn't look like he has exactly the same racing genes though
Some interesting names who showed themselves in La Marseillaise: Pinot tried to get in late escape; Bardet sprinted pretty close, Julien Simon sameAs brief video of the finish:
(then again, it might just be the French trying to show themselves in their own country)
