Aylesbury to Buckingham – 17 Miles
As you leave Aylesbury the national speed limit begins after you exit the roundabout for Watermead. The first section of road between here and Hardwick is through a series of twisting curves controlled by solid white lines. Be careful when the road rises at Weedon Hill as this particular location has seen more than its fair share of collisions over the years. Ease off and maintain a good view ahead.
From Aylesbury you drop downhill towards a left-hand curve and the village of Hardwick. You will pass over a bridge and hidden on your left, just on the exit side, is an entrance to a farm. As you drop down the hill you will notice the SLOW sign painted onto the road; it is there for a reason.
Look to the left and you will see the farm, the entrance opens onto the road just around the curve. You can see the track and any vehicles moving to or from the road. But be aware that vehicles may be turning into the track from the main road still out of your view, so reduce speed and wait until you can see the way ahead is clear. Be aware and look properly.
Just past the farm the road sweeps around to the right, watch out for the metal inspection cover towards the nearside and on the riding line.
When travelling towards Aylesbury the road through Hardwick is a left-hand bend. The riding line would normally be towards the crown of the road but beware there are three metal inspection covers right on the riding line through here so modify your road position and reduce the speed accordingly.
