Christian said:There are almost no flat parts in this ITT.
4 km uphill (Côte de St. Rémy de Provence)
3,3 km downhill/flat
4 km uphill (Sommet des Baux de Provence)
2,6 km downhill (very small, windy road)
3,4 km flat
The climb to Les Baux was classified as Cat. 2 in 2012 apparently
That's a total of 17.3k. Profile says 18.2k. And the bolded sections are not in accordance with the profile above. So either your info is wrong or the profile is wrong.
