Yeah, as far as I can tell. I don't think there's any way to know where exactly we will get spawned - I don't know if it's the same place for a meetup as for a solo ride on that route, and I also don't know if the location is always exactly the same for every meetup on a particular route. We might be able to work this stuff out a bit better over time.
You should be able to see when the start banner is coming up because there's usually advertising banners by the side of the road leading up to it, so look out for these - having said that there were miles of those on the London course last night!
Still need to watch what other people are doing straight from the start though - if it had been a normal race last night and a couple of your rivals had gone full gas for those 2km from the start and you'd held back because the timed segment hadn't started, the ones who got away may end up drafting together to a much better time than you could manage solo.
