Here is KMZ file for Stage 17 Route Map with path/point/distance info.

Stage 17 - Wednesday, July 20: Pau - Revel, 239.5 km

After all mountain stages are over, the longest stage is for long breakaway and sprinter jersey contenders.
There are 2 90-degrees corners just in front of the finish line, so if it's rainy or large group rushs to the goal....

I added some path thru the finish line in the city of Revel refering the map below.
