The Royal British Legion's annual Poppy Walk is a gentle 10km walk where participants search for clues en route and test their knowledge of London.
Setting out from the Legion's HQ near London Bridge, participants will be equipped with questions and a Poppy Walk T-shirt and sent on a trail of London's historic streets.
Everyone is welcome, whether they will be walking solo with the dog, or as an all-out team expedition.
There is no minimum sponsorship, but the legion encourages walkers to raise as much as they can to raise funds for their work supporting the armed forces community.
