What the Data Suggests
💪
Strengths to Protect
Exceptional repeatability — the engine keeps firing deep into the ride. Late-ride performance (top 20%) is actually stronger to the opening. Thrives on rides with high segment counts where rivals are already fading. The aerobic base is the asset — protect it.
🎯
Development Area
Peak power and short-burst acceleration. The punch/threshold gap (top 31% vs top 25%) shows where the ceiling is on explosive efforts. Sprint intervals and over-under VO2max work would add a new gear without eroding the aerobic base. The diesel engine is built — adding a turbo is the next step.
📊
The Real Enemy
Absolute peak power output, not endurance. The engine runs clean all day but the rev ceiling is the constraint. Watts from early to late: 472W → 417W (-12%) — barely any drop, which is the signature. The rival who fades less than everyone else still loses to a rider who never needed to fade. One note: Ride 08 looks like a major outlier — averaging top 70% vs your season norm of top 24%. A single bad day (mechanical, illness, off route) is pulling down the headline numbers.
