Take the stairs up from the Tube? You’re climbing the equivalent of Mount Everest in months at these Underground stations
When it comes to your daily commute are you a stander or a stair-taker?
If you opt for the latter, you could be scaling the equivalent of one of the world's highest mountains with every step.
Walking up the stairs instead of taking the lift from London's deepest Tube station Hampstead adds up to 320 steps each day.
Do that 151 times and you will have reached the top of Nepal's Mount Everest, an impressive 8,848 metres.
If you started that today, you would have scaled the equivalent of the entire mountain – a feat completed by just 4,000 people – by 22 March (assuming you also did it on weekends, of course). And that's without having to risk frostbite or altitude sickness.
Likewise, climbing up the steps at Covent Garden 166 times would get you to the summit of US mountain Denali, while taking the stairs at Highgate 157 times equals the 5,895 metre height of Kilimanjaro.
And if you were to climb up the longest escalators on the London Underground's network at Angel 133 times, you would have conquered Mont Blanc. Which might go some way towards explaining why someone decided to ski down them a few years back.
All this is according to research by outerwear retailer Snow + Rock, which is running an Urban Mountains campaign to encourage Londoners to “celebrate the adventures that can be found in urban settings”.
“Alternatively, conquering Snowdon each month through Holborn will encourage people to walk on the left rather than stand on the right,” the specialist said.
Snow + Rock's head of marketing Inga Taylor added: “Next time you’re riding up the escalator, consider walking and in time you could have scaled the equivalent of one of the world’s peaks.”
The feeling of achievement will almost certainly be the same as the one experienced by those so-called “real” mountaineers….
