Walked 2470 miles in 2012
in 2012, I've walked (and ran) 2470 miles. My goal was to cover at least 2012 miles, so I ended up 458 miles ahead of my goal. Most of this was outdoors (my preference) including hikes in the Olympics, Mount Rainier, Utah's Zion, Bryce Canyon, Arches, and Grand-Staircase-Escalante. When Seattle's rain and short days prevailed, there was some indoor walking on a treadmill.
Another measure - 4,873,398 steps on my trusty Omron pedometer.
From an analysis standpoint, it is not really a Gaussian distribution; more like a Weibull it has sort of a long tail
For 2013 - I aspire to hike a section of the Pacific Crest Trail (perhaps the 500 mile Washington segment)
