People enjoying stays at central London hotels could be worried about overindulging in the capital's wide choice of eateries.
However, the answer could be to sign up to a City Jogging Tour and see the sights of London while partaking in some exercise to burn off any extra pounds. The tours have been running since 2010 and aim to offer visitors a unique perspective of the capital.
"This concept offers an alternative to being jammed in a bus," founder and runner Hope Sloly told London's Evening Standard.
"In addition, joggers see so much more than on a conventional walking tour."
Scheduled tours are available for both novice and more experienced runners and cost £26 each, while customised tours are priced at £46. Bookings need to be made 48 hours in advance via the City Jogging Tours website.
There are a number of different routes organised by the tour company include a shorter run that begins at Nelson's Column and goes past iconic landmarks such as the London Eye, Big Ben and the Houses of Parliament, Westminster Abbey and Buckingham Palace.
Longer runs start at the O2 Arena and take in parts of Greenwich such as the National Maritime Museum and Royal Observatory.
Evening Standard journalist Antonia Kanczula described her jogging tour as challenging but a great way to see the city.
"Warm-up and cool-down included, it's taken around an hour and has forced me to run at a pace a notch higher than my usual," said Kanczula.
"I've seen some of London's finest sights and gained the impetus to tackle more city-centric runs."
