Well the WC has only been assigned to Imola at the beginning of this month...
I am not sure how the TT in Martigny would have looked like and if for example Ganna would have been the topfavorite on that course?
But I get what you mean offcourse, Campenaerts was like 10 days ago already in Imola practicing on the course while Van Aert was going all out in the Tour. Sidenote however is that the course is not difficult/technical nor is it very long (shortest WC TT ever?).
It will thus not be a case of knowing every corner of the course in perfection or saving energy; it will be all out from the beginning for all riders and just go as hard as they can untill the finish (quite obvious I know
).
Looking forward to the TT though could very well be exiting.
