What is 100in1Day?

On June 3 2017, London will feature 100+ interventions. Leading up to the day the Urban League of London and Evergreen seek to inspire citizens to pilot their city changing ideas with the intention that some of these ideas will be able to foster lasting change in our city.

100In1Day has the power to inspire citizen involvement by bringing people together for change—having the power to motivate leaders to consider new approaches to problems it aids in producing ideas that can grow beyond just one day.

How did 100In1Day start?

100En1Dia started in 2012 by a group of students that intended to launch six urban interventions that would maximize the potential of the city. Over beers they decided to be more ambitious, and launch 100 urban interventions, that would take place in one day. On May 26, 2012, over 250 urban interventions took place in Bogotá, and a phenomenon was born, that has since spread to over 31 cities around the world.
