Berbie has released TrailRunner, a new application designed for all people doing long distance sports that helps plan and journalize workouts. The software is a route planner for people who enjoy running, biking, skiing, and other forms of outdoor sports, and works with the Nike+iPod Sport Kit. Users can plan workout routes on a geographical map, export route directions as small "NanoMaps" onto an iPod, and import workout data from the Nike + iPod Sport Kit back into the workout diary. TrailRunner also features an exercise plan, .Mac weblog publishing capability, GPS/GPX/KML import/export functionality, and an integrated map with elevation data from global mapping services such as USGS topo maps. TrailRunner is available for free, and requires Mac OS X 10.4 or later.
