PIII: Marathon Training and Nutrition

Published on August 22, 2016 by Dr. NavNirat Nibber

In the final post of our Marathon Series we examine how to optimize nutrition while in the training, competing, and recovery phases of endurance exercise.

I'm sorry, it has to be done, in order to understand why certain foods are best eaten at certain times I have to talk about the biochemistry of carbohydrates, proteins, and fats. But we will make it short and sweet. Click on the image below for a full break down of what to eat and when to eat it. 

FUN FACT:

Scientists have developed new technology that allows athletes to get personalised meal plans based on calculations of predicted glycemic response. These plans assess the specific genetic, metabolic, and environmental factors unique to individuals to help predict how their bodies use different sources of energy in order to optimize nutrition and reach their goals faster.
