(What happens when you pop a map of a big ski area on top of a map of Blighty?)
You've probably never even thought about it before, but a new app released today by the promotional organisations for French ski areas and French holidays - France Montagnes and Atout France – will tell you how your local town or city measures up to a selection of French ski resorts.
The descriptively named, 'French Ski Area Over My Town' app enables you to see exactly how large the key French ski areas are by measuring them against the size of your own town, overlaying the two maps.
The results are slightly more impressive than we may have thought, which is probably the point, and help gives you an idea of how far you may have skied on your holiday. And indeed how much work must go in to preparing the pistes and maintaining safety at these resorts.
For example, who knew that the Three Valleys would sprawl across much of Sussex between Brighton and Crawley? Or that the Espace Killy of Tignes and Val d'Isère would cover much of Central London, from Highgate and Hampstead in the north, to Greenwich in the southeast?
