I mean that basically how the Tour looked like before. Most parts of France are very flat and I think it makes sense to visit those as well. I think the ridiculousness of broadcasting all stages from start and the new generation with very short attention span forced a change.
Personally I like it to be a lot of sprint stages and breakawaystages combined with long decisive time trials and a few well designed mountain stages.
I liked the route of last year's Tour. I like how the mountain stages were distributed.
I liked the first two mountain stages very soon in the route.
I would change just a couple things. I would introduce a flat Time trial with 55/60 km between the Pyrenees and the alpes, and i would change the ITT of Combloux for a pure mountain Time Trial. I want something like a time trial to Alpe d'huez in 2004, in the Tour again.
The stage of Grand Colombier should also had another climb like Mont du chat.
With this changes, it would a very good route, just like i think it should be.
7 mountain stages distributed between the 3 weeks, one flat ITT, one mountain ITT, 3/4 medium mountain stages, 8/9 flat stages.
