Once you’ve arrived at the pedometer site, choose your country (if outside the US), state, and type in your city. As on the original Google Map site you can scroll around the map and zoom in/out to focus on the area that you’ll be riding (walking, running, whatever). The app can not only save a route that you’ve mapped, it can also create a TinyURL at the same time. I used this to map the route I ride between work and home.
This app is great, but the site is made even better by the “Acknowledgements and references” section. (Scroll down below the map, the section is on the left side with all the other text.) The links to all the enabling technologies and resources are awesome!
The only problem I’ve seen so far is printing. Clicking the “Print map” link is supposed to reformat the map for printing, but on my browser it opens up the print dialog. I have to cancel the print dialog to view the reformatted map. I’m using Firefox 1.0.1 on a PowerBook G4 running Mac OS X Panther v10.3.9. It’s an easy enough workaround, and until I get around to updating Firefox I’m not going to report this as a bug.
