I just love the dailymile! I started using it maybe a month ago or so. I've had the Nike+ for 3 or 4 years, but I guess it is just something about the dailymile site that I love. For those of you who don't know what it is, here is the website
www.dailymile.com. You just track your workouts and what I love about it, is it isn't just for running (even though I am a running freak). But you can put your mileage in for biking, swimming, elliptical, etc.. and it just keeps adding up your mileage for you. It is crazy to look back to see how much I have done. You can add friends (kind of like a facebook type of thing) and you can send/receive motivation, etc.
