The VeloNews Fast Talk podcast is your source for the best advice and most interesting insight on what it takes to become a better cyclist. Listen in as VeloNews columnist Trevor Connor and editor Caley Fretz discuss a range of topics, including training, physiology, technology, and more.

Forget what you thought you knew about sports nutrition. New science shows that cyclists should consider periodizing their nutrition, much like they periodize their training. We speak with Dr. John Hawley, one of the top experts in the world about the cutting edge trends in sports nutrition. Hawley also debunks myths about Ketogenic diets and explains the difference between race and training nutrition.

Plus, we talk to Cannondale-Drapac’s Toms Skujins and national champion Joey Rosskopf about how they use nutrition in the real world.

This episode of Fast Talk is presented by Quarq.
