Too Much Data

I have been tracking my runs with an iPhone app since 2011. I’ve tracking nearly 1200 runs for a total of over 4300 miles. Every run is ranked against other runs of that distance. With so much data, this means that when there is big difference in my pace, there is huge difference in the ranking. I recently logged my 47th fastest run and two days later, my 515th fastest run. Where I run, how I feel and the weather make a huge difference in my performance, even from day to day.
