What the Data Suggests
💪
Strengths to Protect
Explosive anaerobic power on short steep climbs. Opening-segment aggression (top 42% on S1–S2). Wall-gradient efforts where torque beats sustained output. Don't over-train aerobic base at the expense of peak power — that edge is real.
🎯
Development Area
Aerobic threshold and repeatability — the gap between S1 (top 42%) and S7+ (top 45%) is 4 percentile points. Even closing that to 5 points would be transformative on long-format rides. Target: 2×20 threshold work and back-to-back climbing days to build the aerobic floor.
📊
The Real Enemy
Fatigue, not segment type. Power drops 29% from short to long segments (346W → 245W). The issue is power-at-fatigue (FTP relative to peak power) — on a fresh day the ceiling is genuinely high.
