The stage profile looks exactly like this stage in TDF back in 2011 TDF 2011 Stage 13 Results , and a sprinter/classic rider won..Depends on Pedersen and Trek. If Pedersen really wants that Pink jersey back they will go for it and hope no on really goes full on the climb/Pedersen can come back afterwards.
Honestly If I'm Trek I just send Vacek in the break. He can win and even if he doesn't he can get pink.
