I ran a 5k race today. I shaved almost a full minute from my time last year. I contribute the improvement to my diet. I've finely tune my paleo/primal diet into what I called the True Primal Way of Eating. Here are my results from last year and this year.
This is last years results. Gun time was 24:02 and chip time was 23:49. My pace was 7:40 per mile.
