I finished just over 20 minutes ahead of Adam and Bill, which in hindsight I regret - wish we'd finished together! It's hard to explain but after several hours I remember we started so split up a bit on some climbs etc. and we all decided to just go at our own pace to the end. I think they would feel under pressure to go a little faster than they wanted if I was on the front all the time. Also, towards the end of a long ride like that the challenge becomes about the discomfort of that amount of time on the bike as anything else, so it also feels psychologically difficult to go slower or keep waiting.
At one point all 3 of us were separated but Adam and Bill met back up. I stopped for a while at the final food stop and had a bowl of pasta, hoping and thinking they would re-join me there but they never arrived - I later found out they'd stopped in a layby with Adam's wife in the unofficial support car just a mile or two back up the road (unaware of the official food stop I was at) so eventually I set off on my own. If I'd known it was only 20 minutes between us I think I'd have waited - but there is a part of you by that point that just wants to get to the finish ASAP too!
Maybe 10mph average is more realistic so 9 hours to complete the 95 mile. Hopefully on Sunday going to try a 5 hour ride and see how far that gets me, and how many ft of climbing.
