Dog walking routes?

[Amy]

Does anyone know of any circular walks around Hanwell that are about 1 1/2 hours?.  I walk everyday with my dog and generally in the direction of Hanwell Fields or around Hornton, but am keen to find out some more walks particularly in the direction of Mollington.
If anyone knows any good walks I know my dog would appreciate a change of scene!
I must add that Hanwell village and area is so beautiful at the moment - particularly with all the blossom around the churchyard - go and have a look!!
Thanks so much.
