Stage 4 is another big opportunity for the sprinters. The final 100 km should be fast with speeds in the 45-50 km/hr range. This finishing stretch does not have any technical sections, so prepare for all of the major teams to be jockeying for leadout position.

We modeled the peloton as a single rider using the typical pulling power exhibited by riders at the front of the main group. Try using the Time Analysis Tool to find sections on each course where different types of riders may have an advantage. For example a lighter rider with slightly less power will show gains on the climbs.
