Van der Poel is better than ever this year at 30, and Pedersen's progress is even more evident; he's also 30.There should be a top ceiling for either of them. If both improve significantly year after year even after 30 with everything going on (crashes, intense racing all year round, media pressure), I would find that hard to explain.
Pogacar turns 27 in September. Athletes typically improve in their twenties, and the prime age is usually 28 (this is an average).
