You've seen this play out at the last Tour and the one prior. Bernal can accelerate away from the others. He could do it before Froome was hurt in 2018 but instead took some turns to keep him in contact. Froome chased Thomas who had Dumolin on the ropes and GT was smart and strong enough to turn the last 2km into a track pursuit; taking the stage and valuable time. Froome was effectively done then.I'm looking forward to the moment in the first big mountain stage when Sivakov or whoever the last domestique is peels off, and Bernal Thomas and Froome all look at each other and say - who pulls now?
Last year Geraint attempted the same strategy and Bernal had only Pinot to worry about. We're all still wondering how a full length Tour without Pinot's injury would have played out....All things being equal; Bernal is the best suited to a climber's Tour. The other two won't have the luxury of sitting until the last domestique pulls off as the competition has gotten better and will be even more aggressive.
