I used to jog but now I walk because my knees give out otherwise. Being the obsessive compulsive computer geek that I am, I was delighted to find a website that would calculate the number of miles I walked by using a hack to Google Maps. It took me a few minutes to get the hang of it, but once I got started it was pretty easy. I chose the hybrid option so I could see the street names along with an aerial view of the route I usually take on my Saturday walks (click here to see an example). I was delighted to see that I walked about 4.3679 miles.
The cool thing is that you can save the URL and send it to someone else or keep in in a spreadsheet.
Here is the what it says in the FAQ section:
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.
