Tinkoff is a nutter and this challenge is a joke - one million euros, shared between 4, is small change to these guys. Nonetheless I reckon there should be some prize for the rider who finishes all 3 GTs in the lowest total time - though not sure if anyone but Adam Hansen would go for it.
But I can see Nibbles and Bertie going for the Giro - Tour double - they've both won all 3 now, so this would be the chance to go up a level. For Nibbles it's his home tour, so that's an added pull, plus the course is reputed to be less gruelling this year with fewer summit finishes. But what they don't want is to appear at the Tour, having done the Giro, and face Froome and Quintana fresh as daisies. Even if all four started the Giro, there would always be the sense that someone might be holding back with a view to the Tour.
Obviously the last person to do the Giro-Tour double was Pantani, doped to the gills.
I still reckon they should swap the Giro and Vuelta round, and leave a longer gap after the tour, to encourage people to do the double, but its a huge leap to expect riders to be competitive in all three - legally at least
