One thought I had was to have a bigger hub earlier - at around 30miles. Long enough for some people to want to stop, but before it gets countrified. That would hopefully thin out the stream a bit earlier and reduce the likelihood of serious accidents where access and passing are harder.
But essentially what's been said ^^^ - early start and you get round fine, later and you may have hold ups and be prepared to chill.
