I have never used all of it, but at the western end, near Reading it is pretty appalling, lots of pavement, unsurfaced tracks and micky mouse bits of path. I cycle to and from London occasionally and just make up a route from Richmond Twickenham, Feltham Ashford Windsor Winkfield Hurst Woodley Reading. There are lots of options and some quite nice roads.
