Nothing humbles you more than running at the speed of a zesty tortoise, but I have come to love and appreciate the brutality of Zone 2 training. Today's run was nothing special - just under 6 miles at 71 minutes, with an 88% efficiency score at staying in Zone 2. I love to run fast, but the name of the game when training like this is to let my heart rate run the show, not my pace.
Why? Because this slow, almost boring, conversational pace is doing way more than it looks. Zone 2 builds your aerobic base and trains your body to burn fat instead of torching through carbs, and it's also one of the best things you can do for your blood sugar, your heart, and your lifespan. In short: It's how you actually get faster. Almost every endurance athlete spends most of their training right here at this easy pace, and I have already noticed the difference in my sprints and reasonable run club runs. I'm training for two back to back HYROX races in December, with eyes on an Ironman 70.3 (or full) next year, one slow mile at a time.
