After 12 years of running, the last 2.5 more seriously, I finally bought a GPS. It is a basic Timex, but a good "experimental" GPS. I think it will fit my needs for now. I just thought I should be more consistent in my pacing and track my mileage better to improve on my future marathon times. I took it out for a test last evening. It worked well, but I found out I run really slow (it was just a recovery run, but slow). It's hard not to look at it every few minutes and not trip on things. I guess I will get used to that in the future and I don't plan to use it for every run, I still enjoy my most minimal runs the best.
