I do think it would add excitement to the race to have it return to the Champs-Elysees every few years, instead of every year, but I understand that it is the Tour of France, and as such the most proper place to finish it is within the capital city around one of the most iconic buildings in the world.
I would like to see some climbs. I was hoping a spoiler would stick off the front and ruin the sprinters' day. THAT would be an exciting end to the Tour. I find the Champs-Elysees circuit to be exciting just due to the raw speed the riders obtain and the sporadic random attacks off the front. I find the sprint to be dull and anti-climatic after a dozen attacks off the front over 60 kmph. And I enjoy watching sprints. Maybe it has just been too many years of the same.
