Path Profiler app

Ever thought how handy it'd be if you could have one of those route profiles like you get to show the climbs, altitudes and descents on each stage of a bike race? Well, you can provided you have the relevant Ordnance Survey map, a pencil and the know-how.

But what if you haven't got any of those or are riding further afield, perhaps somewhere where OS maps aren't available, such as Foreign? The answer is here - a very useful little application that uses Google Maps, allowing you to select a start, several checkpoints and a finish, and then - as if by magic but probably actually using algorithms or sumfink, draws the desired profile for you. What's more, you can have it in Imperial or metric too. This can then be used alongside a gradient calculator, such as the one here.

The page is ugly, but it works and that's what matters!

Example: Cambridge - Haverhill - Great Thurlow - Bury St. Edmunds - Newmarket - Cambridge, 100km following the A roads. (Click to see it full-size, which makes it look a lot better)
