Froome showing some third week weakness today - as you'd expect from a Giro-Tour double attempt.
Dumoulin on the other hand...
Couldn’t have anything to do with the age difference between them, could it? Froome at 33 is expected to recover as quickly as Dumoulin at 27? Really? Froome at 33 is supposed to be better than anyone and everyone much younger? Froome has already won more Tours past the age of 30 than anyone else in history. Even if he and Dumo were squeaky clean, and hadn't exhibited any unusual transformation, Froome is at the age when riders historically have shown major declines. Dumo is at the age when historically they have begun to peak. Other things being equal, you would predict Dumo would hold up better in the Tour following the Giro.
I'm not saying Dumo isn't suspicious. He's well on his way to a double performance that no one since Pantani has managed. But even if you believe he came from as unremarkable beginning as Froome, he hasn’t yet come close to accomplishing what Froome has. Dumoulin now is about equivalent to Froome in 2012 or 2013. He appears to be one of the best GC riders in the world at the moment, but there’s still a gigantic step up from there to one of the best of all time.
Since 2011, Froome has ridden 14 Grand Tours, two almost every year. That has to take a huge toll on the body. He’s won six, finished second in four others, and will almost certainly at least podium in this Tour. He crashed out of two others. The only GT he finished during this period and didn’t podium was the Vuelta in 2012, after riding the Tour and having no experience in doing a double. Give Dumoulin a few years to approach a record like that before comparing him to Froome in terms of transformation.
