It's more like on how realistic it will be to perform good, decision likely to be made after the Tour. If Pogi would ride through the Tour and to win it by minutes, then he likely will be fresh enough for Olympics. If his form instead fades at the Tour, then giving it a crack at Worlds RR is pretty much it. And this year i am sure that Rogla will go for both too, so there is that. All in all you will still need to be relatively fresh at the Tour and beyond, otherwise chances for results and participations are low.
