Improving my 5K pace

Instead of merely getting through my morning run today I concentrated on maintaining a faster pace. As I gear up for my first 5K (144 days from now) my focus has been on increasing my distance and duration rather than speed. I think we all have a natural pace where we run without thinking about running. I'm guessing this is why most people run, to reach a state where exercise and enjoyment come together. This morning was not one of those times. I started out at a 9:55/min pace as a warm up and brought up my speed to the point where I finished with an average pace of about 9:15. I have run faster than that – in fact I once did a mile in about 7:50 but I haven't come close to that time again. This leads me to think that I never really attained that pace in the first place, perhaps my Nike+ Sportband was not properly calibrated. By the way, it appears as though Nike is no longer listing the Sportsband on their online store. I hope they decide to fix the problems with this unit rather than give up on it. There's nothing else out there that provides the same utility for anything close to its $59 price. The alternative is to use the Nike+ sensor with an iPod but since many (including myself) don't own an iPod or like to listen to music while running it's an unsatisfactory solution. Besides that, an iPod costs a lot more than the Sportband.
