There’s a new Google Maps mashup called Gmaps Pedometer that allows you to draw the coordinates of your running route and then calculates the mileage.  I did it for the run I do most often in my neighborhood and you can view it here.

As you can see it doesn’t take into account the curves in the road so it basically draws a straight line from one coordinate to another.  I tried to make as many coordinate points as possible to compensate but it still comes up short of the true mileage (I know, because I’ve clocked it a couple of times in different cars).  What should be a little over four miles shows up as 3.6 miles.

Of course you could say that I’ve been giving myself more credit than I’m due, but I refuse to believe that I’m in such bad shape that my average time is so bad that it takes me as long as it does to just go 3.6 miles…and no I’m not going to reveal my average time.  Let’s just say slower than the hare and faster than the tortoise.
