Update: Unfortunately all the free codes have now been issued. However you can still purchase the application from the Apple App store for only $2.99.
WalkJogRun.net's iPhone and iPod Touch application can help you find exercise routes from the premiere route mapping site directly from your mobile phone. The application uses the iPhone and iPod Touch’s built-in location services to find routes where ever you are. The application also allows you to view the routes that you have uploaded yourself to WalkJogRun.net, in one convenient place.
The application normally costs $2.99 but WalkJogRun.net are generously allowing 20 Google Maps Mania readers to download the application for free. To get a free code to download the application just leave a comment on this post with your e-mail address. The codes will be given away on a strictly first come, first served basis.
Comments on Google Maps Mania are moderated and I will not publish your e-mail address. I will therefore be the only one who will see your address.
Unfortunately Apple restricts the codes so that they can only be used in the US Apple app store. The codes expire four weeks from today and are only good for a single redemption. To use the code I e-mail you just click "redeem" from the iTunes store home page.
