Looks like Vingegaard's mechanic forgot to set the power assist level from the electric motor causing the unexpected high power readings on the power meter
Even Vingegaard himself was surprised by the scale of his victory, telling reporters afterwards: "It was one of my best days on the bike ever, so good that at one point I even doubted my power metre, it was showing so high.
"But I've prepared for this for so long and all the hard work paid off."
Vingegaard was even prepared to share a little of his power data that he had not expected to see.
"It was on the flat part of the course, I was holding back and thinking I wanted to do around 360 watts," he said. "However, I ended up doing 380 watts between the two climbs."
