As a runner I have a big ego. I love comparing myself to others on Strava and I love getting kudos and giving kudos. I enjoy seeing the paces my peers produce on their runs and comparing their paces and heart rates to mine. It’s a lot of fun and I’m so pleased I can do this with like-minded people who care about fitness and tracking data and performance. Strava is awesome for this. Also, being a data geek from the analytics software world I love tracking numbers and watching the metrics evolve over time.Over the last year I transformed my body from sugar burning to fat burning as a source of fuel for endurance running. I lost nearly twenty pounds or close to 10kg in the process and have body fat somewhere between 7-9%. This was mostly achieved by reducing sugars from my diet. You can read more about my transition to reducing sugars in this post.
In the last few months I’ve gone through another transition based on Dr. Phil Maffetone’s MAF technique. His program is based on his 180-formula where you subtract your age from 180 and use that as your target heart rate zone for training. You can add or subtract 5 beats per minute depending on years of athletic experience, injury, or medical condition. Being in my mid forties and a long time runner/athlete my MAF rate is 140. I also used the MAF beta iPhone application to answer MAF’s surveys that recommended a target heart rate of 140bpm.
