A while back, my pal Larry showed me a cool mapping site that lets you take out a virtual tape measure and measure distances arbitrarily. It really hit the spot for figuring out how far I’ve been running.
Today, via Make, I found a Google Maps hack called the Gmaps Pedometer. Using the same awesome technology of Google maps, you can mark out your route it calculates distances automagically. The interface is a lot slicker than map24.com; Use a single click to center the map or drag to pan. Then just double click away to set waypoints.
Even better yet, you can generate your own links to routes you’ve mapped out previously. That’s a great feature. Here’s the route for my 10 mile out and about run.
