Is there a difference between the nutrition and hydration requirements on the bike versus the run?
KM: In general, nutrition tolerance (calories, protein, solids) is higher on the bike versus the run since our muscles tend to consume slightly less oxygen making more available for digestion of nutrients. Furthermore, running jars the stomach, making consumption of solids, protein, and higher calorie counts even more difficult not to mention the ‘how-to-carry’ factor. On the flipside, hydration needs tend to be lower on the bike versus run again due to higher heart rate averages on the run and the fact that temperatures tend to rise as a race carries on. KM: It is important to note that there is a cap to absorption on all nutrients consumed while racing, including water, making nutritional planning essential for each individual athlete. Furthermore, what is appropriate nutritionally for one athlete may spell disaster for another which is why custom nutrition is so important. These are all things I address and help out with when creating custom menu plans, custom race day nutrition pla
