If you ever asked yourself how long your workout routes are and what route you should choose for this evening – then TrailRunner should be your training-partner.
For people who enjoy running, biking or hiking TrailRunner is a route planning application that connects the Nike + iPod sports kit or GPS devices like the Garmin ForeRunner and Garmin Edge with an interactive topo map. Plan and calculate the distances of routes, journalize your workouts and write about your training progress in a weblog published to your .Mac account.
The new Release 1.3 sports a direct connection to Garmin Training Center for Mac OS X.
