I don't know if it counts as "running", I've been training my arse off for the past few months, getting ready to walk The Overland Track in Tasmania later this year.

About 8km each day, with 14-15km walks most weekends (both days) all while carrying a backpack with 10-15kgs in it.

And I use the Strava iphone app to keep track of it. Works a treat (and its free)
