Also seems to suggest you can turn up at an earlier time:
Can I start the ride at the same time as my mates? If you haven't been allocated a start time with your colleague, friend or partner, don't worry! Just turn up at the earlier start time and we will let you start together.
I'm doing this fixed too. A bit concerned by my lack of preparation but committed to doing it. Frighteningly its less than three weeks away!! eek
