Keeping buses and trains safe as we begin to emerge from lockdown presents an unprecedented challenge for our cities and towns - and the serious risk that our streets become choked with cars. In response, there is a new movement of people pledging to use active travel (rather than cars) for our journeys in order to free our streets and keep our planet clean. As part of the Stride and Ride 100k I have pledged to walk, jog, cycle or scoot 100 kilometres in a month. Will you support me?
