(apologies, I don't know how to draw lines on embedded maps)
A suggestion to avoid the Farnborough A road- when you join the Sevenoaks road in Green st.Green, don't turn right, keep going to the roundabout with the A21. Go straight across, and then right onto Old Hill. Follow until Shire Lane, turn left, then first left onto High Elms Rd. Follow this to Downe, turn right onto Rookery Rd- New Rd Hill- Downe Rd. At roundabout, right then left onto Church road- Jackass lane- Gates green rd- Coney Hill Rd- and rejoin original route.

A little hilly, but much nicer than that road.
