We’ve discussed how to use an online pedometer to map and route your runs. Now there’s a new piece of Mac software that promises similar functionality with a much richer interface and a great set of features.

TrailRunner is a freeware application offered by Berbie Software.

“TrailRunner is a route planning software for all kinds of long distance sports . . . . TrailRunner can calculate a route for your desired distance and export directions onto your iPod, giving you a detailed orientation while you are on your way.”

TrailRunner is compatible with the Garmin Forerunner products, promising the ability to “display and manage workouts . . . directly from Garmin Training Center.” Support for the Nike+ Sport kit is available as well. The feature list is too long and too rich to include here, so head over to the TrailRunner home page to check it out for yourself.

At first blush, TrailRunner seemed to be the one killer app I’d like to use to map and manage my run data. The fact that it’s only available for the Mac is a deal killer for me.

Are you using TrailRunner? Let us know in the comments how you like it and if you’d recommend it to the rest of us.
