Dr. Inigo San Millan

We explore the physiology of race season—how to find top-end fitness, how long it takes, and the best ways to do it.

In this episode we have a classic Coach Connor special. We ask a question not many other physiologists are asking: Is an amateur’s zone 2 ride (in a five-zone model) as physiologically taxing as a pro’s zone 2 ride?

We explore the physiological effects of training in the cold, from muscle damage to the increased caloric demands and how to stay warm.

We tackle the always-popular topic of climbing with Sepp Kuss, Dr. Inigo San Millan, Joe Dombrowski, and Ned Overend.

Ouch, it burns! But what causes that burning sensation in our muscles when we work out? Dr. Inigo San Millan and Caley Fretz reveal new science on lactic acid and "the burn".

We are joined by Brent Bookwalter, Lucas Euser, Inigo San Milan, and Grant Holicky to help you determine when you should and shouldn’t push through bad legs, and when you should and shouldn’t do intervals at full gas.

Trevor Connor and editor Caley Fretz are joined by one of the world’s leading cycling physiologists, Inigo San Milan, to bust the myth that power is all that matters.
