What the Data Suggests
💪
Strengths to Protect
High-end speed on flat and rolling terrain. Short explosive efforts when the gradient stays low — that's the ceiling. Top 70% when fresh on opening segments. Fast-twitch recruitment is the edge — don't grind it away with long endurance blocks.
🎯
Development Area
Sustained climbing — the 25-point gap between flat (top 47%) and steep (top 72%) performance is the main story. Threshold climbing work (sweet-spot on 6–10% gradients) would open up more of the Egan route catalog. Target rides with longer sustained pitches to build climbing-specific endurance.
📊
The Real Enemy
Gradient. Once the road tips up beyond 8%, the advantage erodes fast. Egan routes are climb-heavy, so working on climbing-specific power is the highest-leverage investment.
