I thought I would wait a few runs before I calibrated my Nike + iPod. The last 4 runs have been the same distance but have been recorded as a 0.17 mile difference. It should be much closer than this. The reason why I think it thinks the first two runs are longer than the second two are because the first two I ran slow and sluggish. The second two runs I ran faster and probably took bigger strides. My guess is that for it to be the most accurate I will have to calibrate it every few weeks so that it knows I am in better shape.

I have been working on a Nike + iPod website widget program which I hope to have done in a few days. It looks like it will be pretty cool. Also I have a big project for work due tomorrow so I will probably spend tonight working on that.
