Flying Dodo
It'll soon be summer
I'm in two minds whether to have Bison hill in the ride. It is a killer, no doubt the weather will be a bit iffy in November and you are rather exposed to the elements on your way up. The angel on my left shoulder is saying take it out, the devil on my right is saying leave it in. At the moment I'm swaying more to the angelic side.
You could always simply tweak the route, so that at 28.7 miles, instead of going straight on at the mini-roundabout to go up past the visitor centre at Dunstable Downs, you turn left, to go DOWN Bison Hill, then right, back towards Dunstable, up to Dunstable Downs, down the other side to the mini-roundabout again, then straight over towards Studham, carrying on as before.
