Good luck Thorners.

I did the backstreet way to London Bridge for a while and it is fine - you will probably \ could do a bit through Burgess Park which cuts out another bit on the road.

I'm happy to answer any questions if you have any on the route. London Bridge gets pretty busy but is fine.

My advice for riding on the road - don't feel intimidated to cycle right up to the curb, that's where lots of potholes, slippery road markings and various bits to give you punctures are. If you are use to driving you will know most of this, but pedestrians can't here you and often look the wrong way after getting off buses for some reason. Expect the unexpected as they say!

I'm not sure where you live, if in HOP the cycle up Peckham Rye and then coming the back way is easier than coming past One Tree Hill and down past the station.

Dulwich Park is definitely good practise ground, but watch out for all the park runners (I think every Sunday morning) and the dogs will get you some good practise braking quickly!
