Almost half of British people (46 per cent) admit that it has been over a decade since they went running as part of exercise, with many confirming school cross-country put them off for life, according to research by Macmillan Cancer Support.

The study found that one quarter of those surveyed said that embarrassment at being watched by other people put them off the sport, while 15 per cent blamed a lack of time for not running.

The survey of 2,000 adults showed that cleaning the house is a more popular form of exercise than running, with 15 per cent in favour of getting the feather dusters out to keep fit. Also, one in 10 adults admit they would break into a run for the ice-cream van or last orders at the bar.

When asked about signing up to a physical challenge, almost three out of four of those who had signed up for one opted for 10k races, half marathons and full marathons. However, nearly one in 10 admitted to giving up before the finish line.

The research was done to promote Macmillan Cancer Support’s fundraising event OutRun September, which is encouraging Brits to take part and set themselves a running target for the month. Participants are asked to set up a fundraising page and seek sponsorship from friends and family. All money raised will help Macmillan provide services to people affected by cancer.

Team Macmillan coach, Phil Robertson, a fitness and biomechanics expert, said: “Signing up to a running challenge can seem a daunting prospect – especially if you feel unfit, out of shape or haven’t taken to the running track since school. Taking on a challenge that is too ambitious for the time and dedication you can give it, can often lead to disappointment and lack of motivation. It’s best to set a challenge that is realistic while still pushing you out of your comfort zone.

“With 21 per cent of respondents saying they run to unwind, OutRun is an achievable challenge that you can fit around your lifestyle, and help you relax and unwind after a busy day.”
