Yes the course needs to change, but tbh I didn't find the racing too boring today. It's mostly frustating though to see so many teams unwilling to risk anything.
I do get the feeling that everyone was just completely empty near the finish. A lot of riders got dropped, but barely anyone managed to get off the front. Only Wellens made a nice move, but instead of other teams without a Matthews or Gerrans try to join his attack they start riding at the front... helping...???
I think they need to change the final to the one before this final, except keep the 1.5km after the Cauberg. They also need to change the first 100-120km to a 'flat' course. With about 100km to go the course needs start getting hard and nervous.
I'm not 100% sure this works since it could as well mean that the bunch will only be bigger at the bottom of the Cauberg (which was greatly reduced this time), but it could also mean the attackers have more punch left for an attack. Maybe bigger riders dare to attack from further out if they still feel good.
Big chance they will only think: "oh boy I still feel great, let's wait for the Cauberg!!"
That's why the biggest solution is: Finish atleast 10km after the last climb.
