What the Data Suggests
💪
Strengths to Protect
Remarkable consistency — no single segment type is a weakness. Consistent across all segment types with less than 5 percentile points separating any category. That adaptability is rare: most riders have a clear Achilles heel that good routes can exploit. Best gradient: wall-steep (>13%) at top 12%.
🎯
Development Area
Sharpening the best segments into consistent top-10 finishes. Currently 83% top-10 rate — the consistency is there, the peak isn't yet. High-intensity work (VO2max, 30/30s) would push best efforts into the front group.
📊
The Real Enemy
Absolute power, not profile. The data shows manageable fatigue. The consistency is the foundation. The gap to the front isn't about endurance or the wrong segment type — it's about the power number itself. That's the most direct lever.
