That’s what I was thinking too. They clearly had the reins held tight; if it was a one-day race he would have taken up some of the pulling with Bernal to create a bigger gap to the group behind (Yates especially.)Thinking about it I came to the conclusion that DQS must have told him a thousand times "don't overpace, don't overpace, stay smart, don't overpace..." fearing that he will get too enthusiastic and waste his energy.
