In the past ten editions, four have been won by genuine sprinters in a bunch sprint, the rest have been won either from a small group of 2-7 riders or solo (Nibali in 2018).
Edit: In 2019 there were 11 riders in the front group, thought it was less than that.
What I’m really wondering about MSR is whether the pure sprinters have a chance? What’s the ratio of breakaway/bunch finales?
