Ah, that sounds ideal then. I'm starting in Southfields, past the tennis then down to Worple Road to Raynes Park. Along the aforementioned path then alongside the A3 to Tolworth. Current plan is Hogsmill Open Space then Ewell, Epsom and up to the race course via either Chalk Lane or Ashley Road. Followed by some Gratutitous Hills (Hedley Common, Box Hill, Ranmore Common, down White Down, up Coombe Lane then back via misc lanes.
