The physical demands of cyclists and cyclors take center stage in this episode of the CoachCast. Ben Day, a retired pro cyclist and head performance coach of the American Magic team, shares his insights on his transition from pro cycling to yacht racing and the advent of cyclors crewing race boats. 

Cyclors, using their lower-body strength, can produce 30-40% more power than arm grinders, making them more efficient in manipulating sail shapes and setting up the boat for optimal performance. The evolving rules of the America's Cup have opened the door to the importance of cyclists and the physical abilities they bring to the table. 

Learn how absolute power is the key to a great cyclor, and the concerns of watts per kilogram, so critical to World Tour riders, do not apply. Churning out 450 watts for nearly 20 minutes is the baseline for any cyclist or rower looking to take on racing boats skimming the water's surface at 100 kph. Ben and Dirk also examine the training and nutrition it takes to develop and maintain these efforts to claim the trophy of the oldest international competition still operating.
