Google Maps Pedometer Mashup Measures Distance Point By Point

Hackszine's Brian Sawyer points to the great Google Maps mashup Gmaps Pedometer, which allows you to "walk off" distances using a simple method: set your starting point, double-click to add new points along the map, and drag the map wherever you want to go. I can't get enough of it; I just confirmed that a popular exercise route around the lake at my work - on nameless roads and footpaths - is just shy of a mile. I am also fairly obsessive about learning the relative lengths of multiple routes to get places I frequent, but I am also very forgetful, so usually forget to check my end odometer when I arrive, and have never been so obsessed as to attempt to keep a log. Now I can just walk them off in one fell swoop and know once and for all which is the shorter route.
