We're doing it three days in a row. I think this series of one-day races is a little strange with only mountain top finishes when you basically don't have that in any one-day race for the rest of the season (apart from Mont Ventoux challenge).
And the Ventoux Challenge has been cancelled this year because they need resources for the Olympics. The Mercantour Classic will still take place, so there's at least one other race with an MTF.
