About 1 in 5 people surveyed by the British Heart Foundation admitted they could only manage to run 100 metres iStock

Whether you are one of those who jog every morning or pondering how to make that gym membership count, the UK as a whole is filled with a rather unhealthy bunch of couch potatoes. According to new statistics released as part of the British Heart Foundation's brand new fundraising challenge MyMarathon, almost half of women (48%) and two-fifths of men (42%) admitted that they would be out of breath running for a bus. The poll of 2000 people also revealed that almost half of adults (47%) would only be able to manage half a mile or less if they went running, and 1 in 5 admitted they could only manage 100 metres.

In May, the British Heart Foundation is launching a new campaign dubbed MyMarathon, challenging our nation of huffers and puffers to run a marathon over a month and raise money while doing it. That means you have a full month to complete 26.2 miles at any place of your choice and in any way you fancy.

If you are feeling unfit, it can be a daunting task to join the gym and a host of lithe treadmill obsessives, but there are so many other ways to get fit, particularly in London. Rather than paying a fortune for gym memberships that eventually go to waste, take a look at our guide to some of the most beautiful outdoor locations in the capital perfect for exercising with a wonderful view.

Jogging through Parkland Walk

Parkland Walk Dudley Miles

This disused railway line that ran from the late 1800's into 1970 is now a wildlife haven that runs between Finsbury Park and Muswell Hill. According to the Parkland website , the route is around 1.3 to 1.8k between the sections of the railway. Runners are advised: "The most scenic route is via Queens Wood and then Highgate Wood. The easier and shorter route to follow is by joining Archway road and turning right onto Muswell Hill Road." In the spring and summertime the walk is brimming with flora and fauna and you can walk between the dug out line and the old platforms to really get up close with the flowers and trees. A perfect jogging route, etched into the land, Parkland Walk is definitely one for daytime exercise as the tunnel of trees that form around it can get a bit dark and eery at night, but by day is a mini paradise.

Running along Regent's Canal

If you are looking to take in a good solid run then Regent's Canal is the perfect answer. You can cut out the traffic on the roads and increase your workout by nipping around the strolling couples and baby buggies.

Start your run in Angel (Islington) and make your way onto the canal and simply follow the path east towards Limehouse Basin, then you just need to find the Limehouse Cut, past the Olympic Park and run around the Hackney Marshes before heading back to Angel. You get to take in London from a totally new viewpoint as well as getting fit. Of course for those who cannot manage a 13-mile (20.9km) run, this is also wonderful for a stroll.
