What. A. Day. I went to the school at 7 to warm up on the bikes and do the workout on my own because I had to be at a 5k in Provo at 9. The workout was 20x400m. First 5 at 5k pace, second 5 at 2-mile pace, third 5 at mile pace, and last 5 at whatever you have left. Splits were 76,76,76,74,78,72,71,72,72,72,67,69,69,69,69,68,68,70,69,67. Very difficult on my own and the last couple sets weren't near as good as they were last year. I was dying. Anyway, I went to the 5k and just did it at a super easy pace as a cooldown. Halfway through I had to stop and walk because my left chest, shoulder, and arm was aching and going numb.
