Have you ever wondered what tracked more accurately a Nike plus or the treadmill? When I first started running I would track my time by writing down all of the stats the treadmill gave me after a workout. When looking at the numbers I thought the numbers were a little off, was I really only running at a 10 min pace mile? So I decided to use my Nike plus and compare it to the treadmill information. To my surprise the treadmill was off by .25 a mile! Now that is a lot to be off by! Yesterday when I used my Nike plus I ran 3 miles and it paced me at 9.5 a mile. Those numbers made me feel really good. I am running under a 10-minute mile! From now on I am only going to use my Nike plus. Also the great thing about the Nike plus is it keeps track of all of your past times so I don’t have to write anything down after a work out. If you are a runner and don’t have a Nike plus you need to get one! They are the best investment ever!
