Recently I've been attending the Hackathons hosted by Microsoft Austria. It's a really cool office with all the things you need as a developer. I worked with my colleague Reinhard Hafenscher on Wandermap, Runmap and Bikemap for Windows Phone 7 + 8. The first two apps are already released in the Windows store.
With the free Runmap app you can access over 80.000 running routes worldwide instantly. Automatic listing of all routes near your current location, interactive elevation profile, synchronization of your personal route collection and much more. For more information open the download link.
Didn't you always want to visit the lovely Austrian alps? Then this app is perfect for you. Find over 28.000 hiking routes world wide. This free app has the same awesome features as the Runmap WP app.
