The Madeleine is a long, tough climb so it should see a selection made, but with a 25 km descent then 15 kms up the Maurienne valley to the finish there's plenty of time for dropped riders to chase back on. I'd expect a similar size group to Sunday contesting the finish, unless someone is on a super day (and the rest day was yesterday so someone might be full of beans today) and goes hard early on the Madeleine.
