(S/E) From Harrow Hilll High Street follow London Road to the junction with Roxeth Hill. Continue to your left on London Road. The road starts to descend and changes its name to Sudbury Hill.
(1) Turn right when you get to South Hill Avenue. Just across to your left here is a signposted bridle path officially know as Green Lane but known to locals as 'Piggy Lane'. This is an ancient wooded track which you follow to Sudbury Hill.
(2) At the bottom of the lane turn left and walk along South Vale to join Greenford Road. Cross the railway line to your right. Turn left into Rosebank Avenue. You are now sandwiched between two railway lines. Follow Rosebank Avenue and then Maybank Avenue until you reach Harrow Road.
(3) Cross the road into Elms Lane and keep left.
(4) Look out for the entrance to Elmwood Park on your left. It is a fairly steep climb to the top of the park but well worth it for the views from the summit. The park is small, and is known locally as 'The Pimple'! Exit the park onto Sudbury Court Road. Turn left to join Sudbury Court Drive, then go right, crossing to the other side of this busy dual carriageway when you can.
(5) Turn left into Mulgrave Road. This will take you on to Pebworth Road, where the signposted entrance to the bridle path back up to Harrow Hill is just ahead of you. Follow signs across the Harrow School estate. A steep climb up Football Lane takes you on to Peterborough Road, where you go left to rejoin your starting point.(S/E)
