Looking back, it is always easy to identify the pivotal moments in a championship. Last year, it was the Barcelona test, when Honda brought a new chassis which gave Marc Márquez the confidence he had been lacking. In 2015, it was arguably Motegi, where Valentino Rossi stayed ahead of Jorge Lorenzo, but the effort it took in the difficult conditions left him drained at the start of a long and exhausting set of flyaways. In 2012 it was Misano, where a tire warmer got stuck to Dani Pedrosa's brake disc, forcing him to start from the back of the grid, and leaving him in a position to get tangled up with Hector Barbera, and crash out of the race.
In the midst of a racing season, however, such pivotal points are much harder to identify. Or rather, all too easy to misidentify. After Estoril 2006, everyone thought that Nicky Hayden's championship challenge was over. Valentino Rossi's heartbreaking engine blow up at Mugello looked like it would put paid to his shot at the 2016 title, but he still kept the fight alive for a long time. Anything can happen during the course of a season, so when we look back at a season we can easily overlook the drama of a single race that seemed important at the time. 2015 is a case in point: there were so many twists and turns that it is hard to pinpoint a single turning point, so fans and followers tend to pick their own.
Looking at it now, just five races into a nineteen-race season, it is easy to believe that the races at Jerez and Le Mans will be the turning points we look back at when the bikes are packed up for the final time after Valencia. The three-rider crash at Dry Sack two weeks ago, in which Andrea Dovizioso, Jorge Lorenzo, and Dani Pedrosa managed to all take each other out without any obvious culprit being to blame, had a huge impact on the championship. And Sunday's drama-packed race at Le Mans will surely be spoken of in the same terms. Not just because of who didn't finish the race. But also because where some riders finished is going to have a profound impact on their futures.
