Londoners will have the chance to explore the city with a series of walks throughout September and October.

The challenge is to visit 12 numbered points marked on a map with a circle and match them to their corresponding photo.

British Orienteering say participants can find them in any order with eight winners chosen in a prize draw to win a limited-edition moquette picnic set from London Transport Museum.

The challenges complement TfL’s Streetspace for London plan which aims to make space for walking, improve cycling conditions and enable people to maintain social distancing as the country battles to control the spread of COVId-19.

Peter Hart, chief executive of British Orienteering, said: "Never has the opportunity been greater to promote, enjoy and understand the significant health benefits of being physically active in the outdoors.

"What better way to enjoy being out walking whilst exploring London and completing one of these challenges?

"These introductory fun activities are suitable for all, no matter your fitness level or map reading skills and British Orienteering are delighted to be working with TfL to support people to get out and active around the London boroughs."

The challenge takes place in the areas of Battersea, Stoke Newington and Dalston, Westminster, Clapham and Brixton and Camden.

Julie Dixon, head of customer information, design and partnerships at TfL added: "This pandemic has brought home to everyone just how important health is and the Streetspace for London measures have made it easier than ever to walk around London.

"Walking is great for our mental and physical health and is also vital for improving air quality and reducing congestion, making London a greener, safer place to live."
