Cool, I'm dusting off my pedometer and wearing it all day tomorrow. I know on some days I pretty much make it from bed to the couch (yikes), and other days I run around all day busy as a bee. I'm interested to see how many steps I take.
I just googled a few sites and read the average adult takes 2000 steps in a mile (thats 2.64 ft per step - measure heel to heel). My stride is about 2.8 feet when I'm walking briskly, 2.5 feet when I'm strolling. So that's about 5 miles a day. According to these sites, in normal daily activity people might cover 4000 to 6000 steps, or 2-3 miles. We'd need to come up with at least 4000 additional steps, or 2 miles, or 30 minutes extra walking per day at 4 mph. That's the Surgeon General's recommendation. If you don't get 4-6k from your normal activities, then you increase the time you walk/bike/run to get to the 10k. Makes sense to me too.
