Wow! The Tour could blow apart on day 2. That opening stage crosses the straight separating the island Copenhagen is on to the finish on another island over an 11 mile span of bridges broken only by about a kilometer on a small island midway. Bridge runs east-west. Straight runs north-south. Crosswind maybe? (This is the Denmark, the world leader in wind power; by a large margin. 42% of total energy use. That despite sitting on a huge oil reserve.)
The finish appears to be about 3 km after the bridge. Not much chance to undo the damage done there. This looks custom made for Dec Q-S. Maybe shades of that disasterous day several years ago in Belgium? Netherlands? Could be fun. Put Alaphilippe back in the yellow and make the GC teams scramble a bit.
