On 20 January 2016, photographers will be able to explore London from a new perspective on a secret walking trail, starting at Bank tube station, and culminating at Leica's Royal Exchange store.

The route will take photographers through the heart of the City, with the QuizTrail app posing engaging questions at waypoints along the route. As the questions are answered within the iPhone app, new parts of the trail will be revealed. A host of photo opportunities will be presented along the way, and the participant who captures the best image on the day will win a signed copy of the ‘London Life’ book by celebrated photographer, Colin O’Brien.

The walk is expected to take 20 to 30 minutes, and participants will build their score as they answer each question correctly. Leica will also present the winner of the best score on the day with a special prize.

The Leica Trail can be followed at any time between 11am and 7pm on Wednesday 20 January, and there is a Leica gift for every participant who completes the walk. As a bonus for those finishing between 6pm and 7pm, refreshments will be waiting for them at the end of the route.

Participants can register for the Leica Trail on the Quiz Trail website and the QuizTrail App can be downloaded from the iTunes Store. Although the app is free to download, the Leica Trail will cost £2 to enter, with Leica donating the proceeds to its company charity, PhotoVoice.
