PI1. Lower Resting Heart Rate (RHR)
Your heart is becoming a more efficient pump. If your RHR has dropped by 3–5 bpm since you started, your aerobic engine is officially expanding.
2. Faster Pace for the Same Heart Rate
This is the « Holy Grail » of Zone 2 training. If you’re running 10s/km faster than last month while staying in the same HR zone, you’re becoming a metabolic machine.
3. The « Hunger » Shift
You no longer feel like crashing after a 3-hour ride. Your body is getting better at oxidizing fat and managing glycogen. If you finish your long sessions feeling « hungry » rather than « depleted, » you’re winning.
4. Quality Sleep is Back
Initially, training destroys your sleep. But once you adapt, you fall asleep faster and your HRV (Heart Rate Variability) stabilizes. This is a sign of a healthy nervous system.
5. Better Recovery Post-Brick
Remember when running after biking felt like moving through wet concrete? If that « heavy leg » feeling now disappears after only 15 minutes, your muscles have adapted to the transition.
6. Mental Resilience
The 5 AM alarm doesn’t feel like a choice anymore—it’s just what you do. When the discipline becomes automatic, the finish line is already yours.
Training for a 70.3 is about compounding gains. Don’t look for miracles every day; look for the data.
Comment « WORK » if you want my 70.3 progress tracker to monitor these metrics yourself.
