A London theatre package or weekend break need not mean a break in your New Year health plan. Just because the temptation, once you are there, is to gorge yourself on the free English breakfast, to find a super restaurant for lunch and an even better one for dinner and to return there after the show for pudding, cheese and biscuits and a digestive, it doesn’t mean you should succumb to it!

But just in case you do, and just in case you have picked one of the hotels London offers without a pool or gym and just in case you did all your shopping by bus or by tube then here are some helpful apps to make sure you get a bit of exercise during your Theatre Break.

Obviously the weather is not always on your side, so a jog along the river or a ride around the park may not be on… enter PayAsYouGym

With hundreds of gyms to choose from you can filter on price, location, rating and type.

However there is no getting away from the fact that you are staying in one of the finest cities in the world, and if you are brave enough or the weather (which is generally warmer in London than elsewhere if not dryer) is kind, then take this chance to combine keeping fit with sightseeing.

With thousands of routes all over the world, from walkJogRun.net should be on every runner’s bookmarks. But if it is not then download the iPhone app which gives you the ability to find out what routes are near you – wherever you are.

For the cyclists there are several apps.

In 2010 Barclays Bank helped create a bicycle hire network of 5000 bikes and over 300 docking stations around London. The idea is you go to a docking station, pay your £1 and park it at the docking station at the end of your journey. Great as long as you know where the docking stations are and whether they have a bike or a space. Cycle Hire Widget, an Android app for just this problem has been created and is a great tool for residents and visitors alike.

If you are worried that cycling in London means riding in heavy traffic try out the free London Cycle: Maps & Routes. Whether you hire a bike once there (and there are other hire centres if you don’t fancy lugging one of Boris’s Big Bad Bikes around) or you bring your own, you can get the skinny on a variety of great routes around the capital with this iPhone app.

Finally I can’t find a suitable app for the swimmers amongst you all, but if you are coming to London on a Theatre Break there really are only two indoor options, beyond your hotel’s offering, that are central enough to bear consideration:- the YMCA which, if you are staying at the St Giles Hotel is beneath you and the Oasis Sports Centre at the top of Endell Street.

However what is worth a mention, if you are in London between May and September is the Serpentine Lido in Hyde Park – a freshwater dip great for your complexion as well as your health!

In fact, like the triathletes will be proving this summer, you can swim, cycle and run round Hyde Park for the perfect London workout!
