I've tried to undersand what happened during the blackout from the helicopter footage. I'm not 100% sure but this is what I got, begining from the short cobbled section where Alaf attacked Mocon :
1) alaphilippe in front, then moscon, the duo kiryienka/postlberger just in front of the peloton led by valgren
2) Valgern comes back on postberger and stop working a little after
3) swift attack, folowed by lutsenko, Sagan and a colombian (Gav or Uran)
4) bettiol brings the group back (still Alaf, Moson and Kiry up front)
4) Lutsenko goes again, uran tries to bring back but can't
5) A belgium? (not sure) counter, with gaviria in the wheel. They take back Lutsenko and Kiry but Sagan brings everybody back.
6) Gaviria insists with success and Cort makes the jump. They come back on Moscon and Alaphilippe.
7) The group is disorganised. 2/3 guys take short pull (cant identify them).
8) Cort goes alone in the front and Kristoff takes a pull to come back on the 3 others.
9) Then Bettiol takes the lead, comes back on Cort
10) Final sprint.
So Sagan and Kristoff did things before the 300 last meters. Sagan tried to go in a group, and brought back Gaviria the first time. Kristoff took a pull (not a big one, but it was important).
