Shayne Gaffney is the founder of GC Coaching and one of the most prolific workout designers in structured cycling. He has authored much of Zwift's workout library and created three of its signature training plans: "Build Me Up," "Pebble Pounder," and "201: Your First 5K." His writing on training and performance has appeared in Bicycling, Triathlete, TrainingPeaks, and Zwift Insider, and he holds a USAC Level 1 coaching certification along with a Precision Nutrition Level 1 certification.

That same expertise goes into every plan he publishes. Each one is built on sound training principles: progressive overload, a clear purpose behind every interval, and a structure you can actually follow. Whether you're chasing your first real FTP gain, building toward a gran fondo, or simply want to stop guessing on the trainer, these plans give you a proven, self-guided path to get faster.
