Yes, I have a totally awesome Garmin. But I also have Nike+ enabled shoes (suggested to me by the wonderful people at Pacers Running Store in Alexandria)
Nike+ for my iPod. I didn't get the shoes so that I could use Nike+; they just happened to be the best shoes for me and I'm glad that they are! I bought the Nike+ kit as a way to keep me motivated when I first started running, and it has definitely done just that.
Like the Garmin, the Nike+ has a lot of functionality online to help you track your progress. Every time I plug in my iPod after a run on the treadmill, I can log on to the Nike+ site and see how I did on my last run,
my monthly totals for 2009 (just discovered that one option! Can you tell when I was training for the September half-marathon?),
my average pace, calories burned, and a whole lot more. It's a really awesome tool and as long as I don't have the foot pod for the Garmin, I think I'll be using the Nike+. If you calibrate it, it's actually pretty accurate (I actually calibrated it on the treadmill rather than outside). Yesterday I ran 6.45 miles according to the treadmill and my Nike+ said it was 6.40 miles. I'd say that's pretty accurate! It also feels so good to see how far I've come. I'd definitely recommend it to any new runners who are looking to keep track of their runs and stay motivated.
