To get KM, remove "*1000" on line 3. To get miles, change line 3 to "r = 3959". I'll post the whole GPX parse code in a few days.</div> <script src="https://raw.github.com/moski/gist-Blogger/master/public/gistLoader.js" type="text/javascript"> </script>Andershttp://www.blogger.com/profile/08409330630989692326noreply@blogger.com6
