From my limited knowledge of the WJ's, the favourites in approximate order would be;
Ferguson
Gery
Bego
Venturelli
Isabella Holmgren
Sharp
Molengraaf
Moors
Van Sinaey
The season has been largely dominated by CX riders which is nearly all of the above except Sharp and Bego. The latter can probably only win from a long break, maybe alongside Venturelli or Holmgren. Sharp will likely be employed to try and neutralise in support of Ferguson, who has had a fantastic first season, winning Lomabardy, Flanders and has hardly been off the podium, except where the hills get bigger which shouldn't be a factor here? Dark Horse might be Molengraaf who has had a very quiet road season but got her best result last weekend in Spain and is possibly targetting this?
Someone more informed might have a, very welcome, different opinion?
Quite annoyed I'll be missing this due to work as it's the opener, should be good contest, and GB's only real chance of a road race win.
