Oh, it’s by no means a case of having no form at all, but one could assume he didn’t really hit peak shape until week 3, partly due to said injury. That’s when he was setting the race to his hand. However, due to Tignes being cancelled we’ll never know what it would translate to.https://www.cyclingnews.com/news/egan-bernal-well-on-road-to-recovery-after-missing-giro-ditalia/
I am guessing that he missed about a week of riding (don't know exactly when his injury happened) and was setting records already in May.
Not perfect, but not a big deal also
