We had a shocking change of feelings about shockingly ugly shoes before this amazing episode! The main topic was a pair of studies on energy expenditure and replenishment.

The first was a case study that found massive energy needs beyond base metabolic rate for a full week after an ultra. We zoom out to discuss what that could mean for energy needs during hard training.

The second study examined muscle v. liver glycogen replenishment, highlighting how difficult it can be to stay on top of energy needs. It also featured cod. Cod is a big theme in this episode.

And this one was full of great topics! Other topics: treadmill workouts, an update on the ugly shoe debate from last week, our favorite probiotic and multivitamin, road supershoes for ultras, Tom Evans’ fueling strategy at UTMB, how the use of pacing statistics may change the game, high-dose creatine to counter sleep deprivation, timing of big training weeks before races, heart rate zones v. feel, overcoming injury cycles, our theories for altitude performance, speed v. freshness in workouts, whether the pain cave exists in shorter events, using stairs in training, and lots more.

This one was full of love, laughs, and cod. So much cod.

May we all avoid being in the control group,

-David and Megan
