Jesse Rich | Ultra Running Nutrition vs. Nourishment

Borderlands Trail (+ Ultra) Running

About

In this episode we reframe endurance nutrition to thinking about endurance nourishment.

In efforts under 24 hours, its reasonable to thinkg about it in simple terms of 'nutrition' but in these big multi-day ultra running efforts where you're sleep-deprived and putting enormous pressure on your system you have to think about nourishment. At some point you have to go beyond considering electorlytes and begin considering all the nutrients - fat, protien, etc.

    How many calories do we burn in a 100 miler?How many calories are our body burning in days following without effort?How efficiently are we absorbing calories after one day of consecutive endurance effort?Is there a connection between sleep and absorbing nutrition?When you are at a nutritional deficiency in a race, can you catch back up?Post-multi day run recover requires immense calories.Caffeine is useful only if strategically timed.

This episode offer good advice for anyone running The Speed Project or any multi-day endurance race or run.

Presented by Kiprun.
