I only ever did the Bologna Time Trial Lap route as a free ride, end of the week I lead an event with a couple of laps. After glancing at some past events, the finish seems to be on top of the climb.
Is that right, and if so, does a group ride include the first climb as a lead in? I’d rather know the number of ascents in advance (and adjust number of laps if necessary)? 
I lead this one, we did two laps, The second lap ended at the top of the second KOM, then I just rode down.
See segment below.
I’m sure someone will correct me if I am wrong, but I think that ‘a lap’ is from the start pens to the top of the climb (5.2 miles). From there I think that each added lap would be a return to the start and then back to the top, for an additional 10.4 miles. This makes ‘2 laps’ total to 15.6 miles, or thereabouts.
Thanks, that’s helpful. It was my initial thought, but then I got doubts. Even if not a loop, I always think of a lap as returning to the initial position. 
Funny enough, the event does not show the number of laps but the total distance in the Companion app
