What the Data Suggests
💪
Strengths to Protect
Remarkable consistency — no single segment type is a weakness. Top 12% late in rides vs top 12% early — you warm into efforts rather than fade. That adaptability is rare: most riders have a clear Achilles heel that good routes can exploit. Best gradient: flat/rolling (<6%) at top 12%.
🎯
Development Area
Sharpening the best segments into consistent top-10 finishes. Currently 73% 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 no meaningful fatigue (309W early, 282W late). 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.
