Friendly warning! We're working hard to be accurate. But these are unusual times, so please check that events are still happening.
More than 40 free guided walks will take place over this weekend which aims to feed us all some chilly-but-fresh air as we explore London by foot. There are six new walks for 2016 including a design-focussed strut to support TfL's Transported by Design programme. The routes range in length so even those whose most exercise-appropriate shoes are leopard-print Converse can sign up without a worry. Experienced guides will provide facts and stories about the attractions, landmarks and hidden gems you'll pass along the way, with trails covering everywhere from the West End to Richmond Park. See the full list of events on the Walk London website.
