There are some lovely little trails through Putney common leading all the way to Barnes Green. Hit the start of the unpaved tow path at the end of Putney, take the first left to wiggle round onto the common then hack your way across by any of the mangle of singletrack. Part of it is through a slightly spooky grave yard too. If you get it right you can be off-road pretty much all the way to Barnes. Think its all ok for cyclists too. Just gotta be considerate.
It started off as a normal commute, but somewhere along the line it turned into cyclocross.

A few turns to keep things interesting, and I ended up covered in mud on the Thames path, with a broken spoke and a big grin on my face.
I should do this more often... take detours. It's fun.
