Gmaps Pedometer is a handy site that lets you map out your router for walking or running. It provides you with overall distances, the distance of the last “leg” and a calorie counter. You can even save the route and let others see it. The site describes it this way:
What is this?
This is a little hack that uses Google’s superb mapping application to help record distances traveled during a running or walking workout.
Why?
As a runner training for a marathon for the first time, I found myself wishing I had an easy way to know the exact distance a certain course is, without having to drag a GPS or pedometer around on my runs. Looking at Google Maps, and knowing there was a vibrant community of geeks hacking it, I knew there had to be a way. So here it is.
Note that there’s a reason this is called a pedometer. Considering that you have to choose all the points in your route individually yourself, it’s probably not suitable for driving trips and the like. But I’ve found it suits my purposes pretty well for getting running distances.
