Obviously, as a browser of grough, you’re someone who prides themselves in their walking prowess and the fact you can get up a hill at a good pace.

But how often do you jump in your car to get the wholemeal bread for your packed lunch on the ascent of your favourite fell? Maybe we should all be walking a bit more on the familiar paths between home and pub, shop and office.

So, now you can either feel smug or wracked with guilt when you log on to the walkit.com website.

Here’s what they say: “We want to get people walking more. We think walking in and around town can be a smart choice. No timetables to keep to, no journey delays, no overcrowding. Healthy, green, free, direct, access to services (and sunlight!) en route.

“You might not mind shoe-horning yourself into a rush-hour tube, or paying £3 for a single tube journey, or hanging around for buses, or sitting in traffic, or being fleeced by cab drivers, or depriving yourself of daylight for an hour each day. But we suspect that it can often drive you up the wall.”

You may have gathered from references to rush-hour tubes that this is a London-centred site so far, but should be extended to other areas soon.

The website blurb continues: “We don't in any way pretend that you can substitute walking for all the tube/taxi/bus/car trips you make.

“We do, however, want to at least help you make more informed decisions about whether you choose to walk for all, or part, of any given journey.

“So that's what motivates us, and we hope will motivate you. We're a tiny outfit but we've got big ambitions and plan to launch the service in other UK cities as soon as we can. There are also all sorts of improvements we'd love to make when resources allow.”

This is how it works: you key in your starting point (by, for instance, a postcode) and your end point and the site will work out the best route for you and – here’s the quirky bit that grough likes – tell you how much of that nasty carbon dioxide you’ve avoided chucking into the atmosphere by using your legs rather than your car.

There are no maps available for areas outside London, but you will get a route and the environmental information, so give it a try.

We found out, for example that the journey from grough Cottage (home) to grough Towers (work) would take us 37 minutes if we got a move on, or 73 minutes walking slowly (bloody slowly, it’s only 2½ miles – Ed). Actually, the timings for fast, medium and slow walking work out to roughly six, five and three km/h respectively.

We would also burn 196 calories if we legged it at the top pace and, the important bit, save 0.86kg of CO₂.

Somewhat bizarrely, the route informs us we’ll pass a repair garage and a BP petrol station. Er… we’re on foot, remember.

Still, it’s an interesting concept and may even spur grough to leave the car at home now and again indulge in a little urban walking.
