To be honest, if he was serious then he'd give the Tour a miss; he needs plenty of time training, and racing on the MTB to get back into the rhythm of XCO racing....I mean, if he decides to come in undercooked without any races again, he will come up short, again. He said he won't start XCO until after the Tour, which leaves just a singular world cup in August for him to attend, which won't do much positive for his starting position, despite fraudulent and corrupt Lappartient doing everything in his power to benefit Van der Poel in Glasgow.
If he wants to be serious about this, he comes to Nove Mesto in May.
He's got the engine, we all know that - but that's not enough in XCO; he needs the skills sharpening again - that means racing on the MTB.
