The London Friday Night Skate is a ten to fifteen mile street skate around London, every Friday (hence the name). The Sunday Stroll is a similar event each Sunday at 2pm. They use different routes each time – one day they might take in famous central London roads and sights, another time they will head for some long fast down hills in Camden or Putney, or even a trip to the countryside out at Barnes. The traffic is made aware of the skate as it passes by their volunteer marshals (on skates), and they even have a portable sound system on a bicycle.
