Post-Adaptive Phase: Strategic 8-Week Build
Summary of Strategic Build Phase (Jun 11 – Aug 6)
After completing 17 weeks of Garmin Coach Adaptive (100 runs, 700km), I’m implementing an 8-week progressive build focused on quality over quantity. This phase addresses the missing elements from the previous cycle while preserving the aerobic base.
Key Objectives
- Restore CNS balance: 3x/week maximum to protect testosterone levels
- Fill training gaps: Structured sprints and hill work (completely absent in previous 17 weeks)
- Progressive loading: Start conservative, build to race-ready intensity
- Smart recovery: Walk breaks as a tool, not a weakness
Training Zones (Based on LTHR 175, Max HR 190)
- Z1: 105-140 bpm (Recovery)
- Z2: 142-150 bpm (Base)
- Z3: 152-161 bpm (Tempo)
- Z4: 163-165 bpm (Threshold)
- Z5: 166-191 bpm (VO2max/Speed)
Phase Structure
Weeks 1-2: Restart
- Tempo intervals with walk breaks
- Short hill introductions
- Base maintenance at true Z2
Weeks 3-4: Power Development
- Sprint work begins (6x100m)
- Threshold intervals introduced
- Progressive runs added
Weeks 5-6: Full Intensity
- VO2max sessions (5x800m @175-185 bpm)
- Sprint pyramids
- Tempo/threshold combinations
Weeks 7-8: Peak & Test
- Race-pace specificity
- 5K time trial target: sub-21:50
Critical Warm-up Protocols
Tempo/Threshold Sessions:
- 10-15min @Z2 + 3-4x100m strides
- Total session: 40-50min
VO2max/Sprint Work:
- 15-20min progressive (Z1→Z2→Z3) + dynamic drills
- Total session: 50-60min
Hill Sessions:
- 10-15min to hill base + 3x30s practice runs
- Total session: 40-45min
Recovery Indicators
- Green light: HRV >110, RHR <42, legs feel springy
- Yellow light: HRV 100-110, modify intensity
- Red light: HRV <100, recovery day only
Expected Outcomes
- Restored speed/power (missing from high-volume phase)
- Maintained aerobic base (VO2max 51+)
- Improved hormone profile (testosterone recovery)
- Strategic readiness for next training cycle
Lessons Applied
This phase represents training maturity — knowing when to push and when to preserve. After 3 years of Garmin Coach experiments, this custom approach balances what worked (consistency, structure) with what was missing (power, recovery, life balance).
The goal isn’t just another PR — it’s sustainable performance as a tool for life.
