It is certainly not the same. In a 250+km race you have to manage your efforts quite differently and think tactically in how/when you will respond or not. Like how Pogacar let Evenepoel go in the break in Wollongong and didn't respond. He thought he was playing the long game, but instead he was playing the losing game. A lot depends on how many domestiques you still have at your disposal. At 130km into a race, you are more likely to have your full team ready to close gaps and bring back breaks for you. At km 200, you could be lucky to have still one teammate with you. It is exactly the reason why i predicted Evenepoel to win the OG.
