An earlier start there therefore is. Fifteen minutes earlier. We start at 7.45 am from Nunhead Station and pick up riders from Peckham Rye station (from the bike stands behind McDonalds) at 7.55am. We are joined by riders from Denmark Hill who leave that station at 7.55am (from outside the cafe in Windsor Walk) and join the train in Burgess Park.

We cycle through two parks, north along a traffic-calmed backstreet, onto the pavement-cycling lanes along the New Kent Road, around the Elephant and Castle bypass and then onto the lovely new TfL segregation all the way to Blackfriars. Arrival time approx 8.30am. On time every time. Fun and free.

To book your seat at Denmark Hill text Liz Eden on 07814 515 715. Don’t turn up without warning at Denmark Hill because this branch line will be demand-led (management speak for “may not run if there are no passengers”). For Peckham or Nunhead contact me on 07842 640 207 — or don’t book anything at all and just turn up. All welcome. Free.
