I got my Nike Plus one year ago today. According to the website, in that time, I've run (or walked) 835 miles in 185 hours. Wow. 185 hours? That sounds both awesome and not enough. I don't go by the Nike+ calories burned estimate but if I did, 91,000+ calories sounds like some serious burn. Also, it says that my average pace is 13:21. That's not bad when you consider that I walk with the sensor sometimes. In that time, I've gone from Yellow, Orange, Green, to Blue. I want to turn Purple well before a year from now and increase my mileage over the next year in addition to running faster and injury free.
