I started running aggressively last year and developed bracycardia for the first time. The change to my physiology was pronounced. I was faster and stronger than ever before (even compared to high school performance as I was almost breaking a 12 minute two mile) and my resting pulse rate was in the 40s. I was almost 39 then. I learned some things from that were never clear before. It’s more about the journey than the goal. I was running on a treadmill and started after recovering from surgery. I started at an 8 minute mile pace and could barely run a mile. My goal was to increase the distance instead of speed and gradually worked up to a 10k (50 mins) 5 days a week. Then I was able to work on speed and resistance here and there. I have asthma and remember running through an attack on one occasion to make my distance goal and break from a performance plateau. At the time I was eating a lot of fatty, greasy, meaty foods. The foods were heavy and high in cholesterol. I had tried the ketosis diet the summer before and lost 25 pounds, but I was not intentionally practicing any diet at this time I was running. You don’t achieve performance over night. It’s similar to programming in that it takes practice solving hard problems and listening deeply to your environment. With enough practice and persistence you make goal and are changed as a result.
