Tour ticker says Sagan and Dumoulin (S) have sat up waiting for the rest of the break, and Katusha are chasing it.
Break at 3 minutes is Mikel Landa (Sky), Gorka Izagirre (Movistar), Vincenzo Nibali (Astana), Peter Sagan (Tinkoff), Samuel Dumoulin (AG2R-La Mondiale), Damiano Caruso and Greg Van Avermaet (BMC), Edvald Boasson Hagen and Stephen Cummings (Dimension Data), Tony Gallopin (Lotto-Soudal), Rui Costa (Lampre-Merida), Sylvain Chavanel (Direct Energie), Luke Durbridge, Daryl Impey and Michael Matthews (Orica-BikeExchange)
That is a very strong break ... interesting.
