Participants can win prizes by completing interactive challenges, unlocking clues and answering questions about heart health using the London Heart Trail app.
The trail has been designed to encourage Londoners and visitors to experience the capital in a healthier way and is free to enter, with an optional charity donation to the British Heart Foundation.
It was developed by London & Partners in association with the British Heart Foundation, King’s Health Partners and ExCeL London, and produced by psLIVE with Wildgoose Events creating the app.
The five-day ESC congress will attract 35,000 leading cardiologists to the city and is expected to generate more than £100m in economic benefit.
It takes place just over a year since the Mayor Boris Johnson launched MedCity - an organisation that aims to help the life sciences industry in London and the greater south east of England to thrive.
Johnson said: "It's an honour to welcome thousands of international cardiology experts to London. The focus of the medical world will once more be on our great city as a leader in science, education and medical innovation, making it the perfect opportunity to also get Londoners and visitors thinking about the simple steps they can take to look after their health.
"Walking is one of the best – and healthiest - ways to explore the capital and the London Heart Trail App will signpost some of our greatest attractions, whilst learning about our own health and wellbeing at the same time."
Gordon Innes, CEO of London & Partners, which led the bid to secure the ESC congress for London, commented: "London is the destination of choice for a great variety of people, from business travellers to families on their annual holiday. It is fantastic that in London we are able to make the best of both worlds – drawing in investment while promoting a healthy lifestyle for future generations of Londoners and visitors to our city."
James Rees, executive director, ExCeL London, added: "We are excited to be hosting ESC’s congress this year and to be supporting their mission to reduce the burden of cardiovascular disease in Europe. The heart trail will be a perfect way for London to show its support for this mission and help to drive a legacy of health awareness in London and the UK as a result."
The London Heart Trail will run until 3 September 2015.
