I’m guessing about 8.30 – seem to recall that suited mostly for a 10/10.30 finish.
I’ll have a look see at route options and post up later.
Had a quick glance at route overviews – tire bouchon or London pretzel may suit?
France is mostly flat with the petit kom in both directions – 431m over 61k so should be comfortably <2hrs in a group.
London pretzel again mostly flat with box&fox in the middle 531m over 55k so again should be plenty under 2hr in a group
