riding in a group should take 4-4.1/2 hours and then a loong afternoon on a sunny beach/pub.
so what happened to change the plan? did you all decide to ride back?
You would struggle to get around in under 5 hours, if you had a good geared group who all knew the route you'd be in with a chance, but the road surface through the hills towards the end left you scrubbing your speed at the bottom of the descents (Gravel/pot holes/ blind corners etc) so you gained no momentum for the hills. (Geared riders on the granny ring came to a stop)
There were 3 or 4 stretches where we could get a rhythm together but not enough to claw back time. 5 hours would be a good challenge.. might be worth a revisit next year
