Takes me 20 mins to Pimlico ,so I'm sure 30 mins for your journey would do it. I'm definitely not fit but found it so much easier and qucker than the bus. Be encouraged ,I'm sure you'd love it. We need some clever person to suggest a route though . I always try and avoid the 185 route - Dog Kennel Hill,Camberwell Green ,and absolutely NOT Camberwell new Rd up to the Oval. Here's some of my efforts straight across at the end of Townley Rd up ( traffic free but bit spooky in the dark ) Greendales at the side of JAGS. Across Denmark Hill ,left and right ( not exact ) and down the first bit of Herne Hill Rd ( with the LIbrary )take a left and and a right ( again not exact ) and straight down Poplar Rd ( I think ) . Brings you out at Loughborough junction where you go straight across and keep going straight ,across major junction, then left and this brings you out near the Oval. On the way back ,just past Vauxhall I keep straight on down Kennington Lane ,past the TESCO'S ,turn right at lights across main road straight on and then turn left ,then right and you come to Kennington Park Rd which you can cross by turning right and tiny bit of pavement cycling and then across traffic lights down ( not sure of name ) road opposite and along side of park ,parllel to gahstly Camberwell New Rd . Go straight until you reach John Ruskin St where you turn right and then left down Bethwin Rd and straight across Camberwell Rd, thru Addington Square ,across main road ,and straight on down Edmund Rd ( bit scary in the dark as a bit deserted but only a short bit ) and then straight on down Benhill Rd which brings you out to main rd btwn Camberwell And Peckham ( Peckham Rd ) . I normally go straight across up Wilson Rd and left and right ( not accurate ) into Camberwell Grove.( which is not as steep as you might think ).
