Analyzing Road Racing
Beyond Watts/Kg
Watts/kg is a great fitness metric — but in real road racing it's only part of the story. Using Best Bike Split's Time Analysis Tool on 2016 Tour Down Under Stage 3, we break down how aerodynamic drag dominates flat and sprint scenarios, where raw power matters in a breakaway, and when watts/kg finally wins out on the climbs.
