Twickenham to Enfileld and back again

I wouldn't go central, I used to visit a friend in wood green from putney and found the quickest way was via the outside central route.
Gmaps pedometer says the shortest route is 35 k, which for a guy my size would equate to 2500 calories one way- via the norh circular which i think has a cycle path.
you lucky guy!
hope alls well.

This way? http://www.gmap-pedometer.com/?r=2420571
