Improve Your Marathon Nutrition with Jackie Dikos, RDN, CSSD, CLT

Many of us want to either train for, or improve upon, a great marathon finish.

So we log miles, minutes and hours of running each week. We focus on endurance, speed, flexibility, strength and mental toughness. And, of course, NUTRITION.

You wouldn’t put water in the fuel tank of a Ferrari. Or a Jeep for that matter.

But how does what we eat, and when we eat it, positively influence our race-day performance?

Jackie Dikos is a nutritionist, champion marathoner, and founder of NutritionSuccess. In 2008 and 2012 she participated in the Olympic Marathon trials. She won the 2010 Indianapolis Monumental Marathon and was the 15th place female finisher in the 2008 Chicago Marathon. She is a contributor to Runner’s World, Running Times, Women’s Running and Shape magazines.

In this episode, she teaches us how to fuel and hydrate during training, taper and race day while explaining the importance of macronutrients and how to combine them for optimal energy.

She also talks about why she focuses on a ‘colorful pate”, how and why to calculate sweat-rate and what to do with that information to more effectively leverage aid stations during marathons.

Jackie’s firsthand knowledge and experience provide a host of great information, so don’t be surprised if you listen to this several times to fully absorb these nutrients of fueling wisdom.

Quotes by Jackie:

“I encourage testing Ferritin, Vitamin D, Magnesium, Zinc (levels); those are some big ones that I think would be really beneficial to supplement if someone’s low. It can be night and day in terms of their performance and injury healing.”

“I feel like any time I finally realized I was thirsty, I was too far dehydrated to play catch-up.”

“The goal throughout that entire training cycle is to figure out what foods your body really loves and and what ones it doesn’t really care for.”

“The mirror can be a great guide. If you see muscle forming, but the scale is going up a little bit, it could just be an indicator that muscle mass weighs more than fat mass, and you’re doing a great job of leaning out.”

“I don’t like to focus on calories very much at all. I focus much more on each macronutrient based on the person’s body weight and activity level versus just a pure calories in / calories out approach.”

“Running just took an exciting shift. It wasn’t just working the workout into the day; it felt like it was this active science I was performing.”
