Several times recently I’ve been describing walks and runs to people and thought wouldn’t it be great to be able to plot them out on the amazing Google maps service.

It already does a great job with routes from A to B (say East Dulwich to Marylebone High Street – my current daily bicycle commute).

Imagine being able to put a shape (circle, say) on to a map and then drag its edges to particular co-ordinates or landmarks until you’ve mapped out your route.

Then you could save this route and send it as a link to someone or link to it from your website.

I was just wondering if anyone has any info on anything like this being developed anywhere?
