We're all going on a summer holiday...

As the summer holidays loom, tea time time talk has inevitably turned to 'Where shall we go?' and 'What shall we do?' Just the prospect of spending six weeks at home while the kids run riot is already driving me crazy so that's out of the question. We've got to go somewhere and got to do something, but what?

How about that wilderness trip of a lifetime canoeing down the Yukon? Or a fortnight on safari in Africa? What about biking in Cambodia and Vietnam? Or trekking in China or Nepal? The travel supplements, family adventure brochures and guide books are full of ideas and inspiration. But just thinking of flying five of us to an exotic destination for a hedonistic family adventure doesn't seem very responsible any more. So it's just as well we can't afford it financially as well as environmentally; makes my unfulfilled dreams a little easier to live with.

And so thoughts turned to holidaying at home, which has not been so immediately full of inspiration. After arguing a lot about the best place to go we agreed to compromise and make our destination a journey. So having established that we couldn't go somewhere and that going nowhere was not an option, it was obvious we had to go everywhere. And so emerged a somewhat absurd plan to take on a classic road trip, from one end of the country to the other; from Lands End to John O Groats.

Only thing was we couldn't possibly do it by car; never mind environmentally, just mentally, cooped up in a tin-box day after day, guzzling fuel, enduring the great British summer and accompaniment of traffic jams. No, there's only two green ways to do Lands End to John O Groats - by foot or by bike. And with just six weeks of holiday and three kids, one is clearly impossible and the other..... Well, let's just say we're planning to find out.
