Ultra-Trails

This application has been designed for ultra-runners who want to use their AppleWatch during their ultra-trail workout. The application includes a specialized cartography and a simple interface which allows you to concentrate on your run.

IMPORTANT: To support very long runs, the workout is recorded by the iPhone.
