Season 5 Ep 8 — The Intersection of Cycling & Sailing: Ben Day's Journey to the America's Cup

Aug 16, 2023
Ben Day, retired pro cyclist and head performance coach of the American Magic team, discusses the intersection of cycling and sailing in the America's Cup. Cyclors, with their lower-body strength, play a crucial role in manipulating sail shapes. Absolute power, not watts per kilogram, is key in yacht racing. Training for yacht racing differs from road cycling, and a strong aerobic foundation is crucial. Learn how to contact the team and submit training peaks files to join their talented group of athletes.

INSIGHT

Leg Power Beats Arm Grinders

  • Replacing arm grinders with leg-driven cyclors yields 30–40% more power because legs have greater force capacity than upper bodies.
  • New Zealand's 2018 innovation proved lower-body power advantage and shifted America's Cup design rules and team strategies.
INSIGHT

Smaller Crews Drive More Power Per Person

  • America's Cup crew size dropped to eight, forcing teams to pack power into fewer people and favor cyclors.
  • Configuration will be four technical sailors and four power crew (two cyclors per hull side) for AC37.
