davidk, I work very near you and leave from Northcross Road. How long does your cycle take? I go via The Rye, Peckham Rye, Surrey Canal, through Burgess Park, then cut across Old Kent Road, then up Tower Bridge Road...... Mine takes between 30 and 35 mins......dependent on traffic lights.......etc...... Happy to be part of a bike train in the morning, I have been cycling for over 6 years, so happy to help out.
