Feltham was the only Zone 6 Oyster station omitted from Cycle Orbital. The reason: the ride to Staines was on suburban and busy roads via Ashford with seemingly no viable off-road or pleasing alternative route. Staines, Egham and Virginia Water stations are generally worth the extension fares to access Windsor Park, but on a subsequent exploration a viable recreational route was found through this unprepossessing area known for prisons, detention centres and Heathrow marginalia.
The path alongside the railway deteriorates 0.5 briefly, but you are soon in the inappropriately-named The Pitts park on excellent hoggin-surfaced paths. After, the centrepiece is lovely Bedfont Lakes
Country Park 1.6, but then there are a couple of miles through Ashford with no - or even worse, wholly inadequate - cycle provision. Fortunately the route ends splendidly (L Riverfield Road 5.7) by merging with Spoke 6-7 on the Thames towpath just below Staines.
