If you start from Admaston then you have to wait until you pass narrow railway bridge. Then you can learn how to overtake at moderate speed. It last till very narrow bridge. This part is 3.2 miles. Then after that is 1.7 miles of very fast road until you meet B5061. The 1.7 is so beautiful because you can at last go fast. The corners are so slight you can't believe it. And then you can turn around and do it again but from other end.
