no he should not. what's the point of lining up when your body ain't ready. all that travel for races that aren't used to get in shape, and are quite tough don't make any sense.
Remco should ride when his body is ready for it. not earlier.
Only races that make sense are Bretagne classic and either Tour of Britain or Deutschland Tour. But even then it's better to just get right first, and race from UEC onwards. UEC (TT, RR), Lombardy, Nations Chrono. Ofcourse this won't happen cause Remco will go for WC even though he should not.
