This document provides information on fueling strategies for endurance athletes. It discusses:
1) Endurance athletes deplete their glycogen stores during long duration exercise over 90 minutes, putting them at risk of "bonking" without proper fueling.
2) The body has limited carbohydrate stores that can be depleted during endurance exercise, so athletes must fuel with carbohydrates before, during, and after exercise to prevent low blood sugar.
3) Proper fueling includes consuming carbohydrates and fluids before, during, and after exercise to replenish glycogen stores and support training adaptations.

1. Fueling for Endurance
Kathy G. Wise, RD/LD, LWC, CWP
Director, Health & Wellness
Mercy Medical Center
2. Training for the Run
Endurance athletes spend
months training for a
marathon or triathlon with
a performance goal in
mind.
3. Endurance Athlete
ACSM defines an endurance athlete as one who
trains and competes for 90 minutes or longer
4. Physiologic and Metabolic
Changes of the Endurance Athlete
CatabolicHormone fluctuations
Muscle protein degradation
Glycogen depletion
Depression of the immune system
Changes occur during and after
endurance exercise
5. Catabolic Hormones
Catabolic hormones
Cortisol
Epinephrine
Nor epinephrine
Glucagon
Released in response to vigorous workout
periods and during the recovery process
Necessary for promotion of glucose, protein
and fat as fuel
6. Catabolic Environment for Fueling
Cortisol is released to stimulate glucose
production by the liver and metabolize fat,
protein and carbohydrate
Strenuous exercise results in net protein loss and
decreased protein synthesis
Fat and protein breakdown and glycogen
depletion occur
Catabolic hormones remain elevated for 30 to 60
minutes following a vigorous workout
7. The Endurance Athlete
Physiologic and Metabolic Changes of the
Endurance Athlete put the athlete at high
risk of bonking
8. The Endurance Athlete
• The body of an endurance athlete is like race car
with two fuel tanks
Tank A is the body’s fat stores
Tank B is the body’s carbohydrate stores
9. Limited Fuel Tank
The body can only store 2,000 calories of stored glycogen
10. Draining the Tank
When we exercise for less than 90 minutes,
tank B has sufficient stores to power us through
the activity.
However, when we
exercise for more than
90 minutes, we need
to have a nutritional
plan to prevent the low
fuel light from turning
on.
11. Four Key Areas
Fueling Before Exercise
Fueling During Exercise
Fueling After Exercise
Daily Fueling
12. Fueling Before Exercise
Three or four hours, eat 300-600 calories,
primarily of carbohydrate (2-3g/kg body
weight)
Moderate in protein
Low in fat
Minimize the amount of fiber in this meal
to prevent stomach discomfort during
exercise
Adequate fluids to replace sweat losses
13. Pre-exercise Meal
Oatmeal with milk, fruit and nuts
Turkey sandwich with fruit
Cottage cheese with crackers
and fruit
Toast with peanut butter
14. Fueling During Exercise
Mid-exercise foods can include:
Gels
Energy beans
Energy beverages
Honey
Bananas
Oranges
15. Fueling Frequency
Fuel your body every 45-60 minutes during a
long workout.
ACSM guidelines recommend 30-60 grams of
carbohydrate (120-240 calories) per hour.
Provide the body with fluids and electrolytes.
If the workout is less than 90 minutes, but at a
high intensity, you may want to drink an energy
drink instead of water or bring an energy gel with
you.
16. Fueling After Exercise
Post workout goal is recovery fuel
Replenish glycogen stores
Optimize protein synthesis to repair
damaged muscle tissue and stimulate the
development of new tissue
Replace fluids and electrolytes that were
lost in sweat
17. Window of Opportunity
Within 30 to 60 minutes of exercise
300-400 calories
Carbohydrate (75-100 grams)
Protein (at least 10 grams)
The carbohydrate-to-protein ratio:
3:1 ratio in long, high-intensity workouts
Resistance 2:1 ratio
Endurance 3:1 ratio
Longer distance running/multi event 4:1
Fuel again 2 hours post exercise
18. Post Exercise Fuel
Carbohydrate and Protein Partners
Carbohydrates
Raise insulin levels
Promotes uptake of glucose which turns off the
catabolic hormones
Promotes muscle repletion of glycogen
Protein
Complete protein supplies the necessary amino
acids for protein synthesis and muscle repair
19. Post Exercise Fuel
Utilize High Glycemic Index
Carbohydrates and Protein Combos
Post-exercise foods can include:
Chocolate milk
A high-density nutrition bar
Smoothie with yogurt and fruit
Natural peanut butter and jelly sandwich
Greek yogurt and low fat granola
Fruit and a low fat cheese stick
20. Daily Fueling
The fourth way to prevent your low-fuel
light from turning on is to eat a diet
consistently high in carbohydrates.
Include:
Whole grains
Fruits
Vegetables
Lean protein
(not in cookies and chips)
21. Pre-Event Meal
Exercise performance can be affected by diet
Pre-event meal is an
integral part of
training
Pre-event meal cannot
compensate for a poor
training diet
22. Pre-Event Meal
Focus on Carbohydrate
Prevent weakness and fatigue
Low blood sugar
Inadequate muscle glycogen stores
Ward off hunger
Minimize GI distress
Guarantee optimal hydration
Familiar and tested
23. Optimal Pre-Event Meal
Carbohydrate and fluids
Consumed 2 to 3 hours prior to event
Allow time for digestion and absorption
400 to 500 calories
Low in fat
Low in fiber
Moderate protein
24. Liquid Meals
Liquid carbohydrate can be consumed
when time is limited prior to event
Sources
Sports drinks
Juices
Low-fat, low fiber smoothies or shakes
Liquid yogurt
AVOID carbonated drinks
25. Morning Event Fueling
The night before:
High carbohydrate meal
Early morning:
Light breakfast
Cereal and non-fat milk
Fresh fruit or juice with toast or bagel (limit
fat)
Pancakes or waffles (limit fat)
Non-fat or low-fat fruit yogurt
Liquid meal
26. Afternoon Event
The night before:
High carbohydrate meal
Breakfast:
High carbohydrate meal
Lunch:
Jelly sandwich with a little peanut butter
Fruit with low fat yogurt
Nutrition bar
27. Good Carbohydrates
Higher Glycemic Carbohydrates
potatoes, yams, root vegetables
beans, peas, corn, carrots
wheat bread, cereal, bagels
bananas,
macaroni, spaghetti, brown rice
apples, oranges, bananas, dried fruits
such as raisins
28. Good Proteins
Animal or Plant Complete Proteins
Lean beef
Chicken
Fish
Eggs
Low Fat Cheese, cottage cheese
Greek yogurt
Nuts, peanut butter
Tofu and soy products
29. Good Carbohydrate-Protein Combos
Low fat or fat free milk
Low fat chocolate milk
Low fat yogurt with fruit
Beans, legumes, green peas
Soy milk, Almond milk
30. Performance Foods for Vegetarians
Plant-based protein foods: legumes, tofu,
texturized vegetable and soy protein, quinoa,
nuts and seeds
Plant-based iron-rich foods: legumes, nuts,
seeds, whole and enriched grains, dark green
leafy vegetables, dried fruit
Calcium-rich foods: dairy products, dark green
leafy vegetables, fortified tofu, fortified soy milk
and fruit juices, legumes, nuts
Vitamin B12 sources: dairy products, eggs,
nutritional yeast, fortified foods (soy milk, cereal,
meat analogues)
31. Strategies for Vegetarian Athletes
Meet daily needs for protein and essential amino acids by
eating a variety of plant-based protein sources
Include plant-based iron-rich foods in meals and snacks to
facilitate oxygen transport in the body and promote optimal
respiratory function during exercise
Consume foods high in vitamin C with iron-rich foods to
boost iron absorption
Select foods high in calcium and vitamin D to build strong
bones and reduce risk of stress fractures
If you are vegan (avoids all animal products), choose
vitamin B12-fortified foods or take a vitamin B12
supplement daily
32. Energy Bars
High-carbohydrate bars make great
choices for carbohydrate fueling both
before and during a long workout
70 percent of their calories from
carbohydrates like sugars (brown rice
syrup and sucrose) and grains (oats and
rice crisps)
Most have a high glycemic index
33. Energy Bar Considerations
Select a bar with about 25-40 grams of
carbohydrate
Less than 15 grams of protein
Low in fat
High fat slows digestion, and is not helpful in exercising.
Eat one bar about an hour prior to a long
workout.
If you are exercising for more than an hour, eat
one high-carb bar per hour of exercise and drink
plenty of water.
34. Natural Carbohydrates
Real food, such as fruit, can also be used
for fueling a workout
Fruit, whether dried or fresh, supplies a
shot of carbohydrate that is well digested
Dried fruit can be easily transported and
stored
35. Fruit Considerations
Most fruits provide about 15 grams of
carbohydrate per serving
A serving of dried fruit equals about 1/4 cup, or
the equivalent, of fresh fruit (two nectarine
halves or four dried plums)
Aim for one to two servings before a workout and
two to three fruit servings every hour of running
Be sure to consume with plenty of water to stay
hydrated
36. Carbohydrate Gels
Carbohydrate gels come in small, single- serve packets,
making them portable fuel that you can store in your
pocket
Gels consist of sugars and maltodextrins which are easily
digested
Many gels come with added electrolytes that, as in sports
drinks, help maintain fluid balance.
Some gels also have additions, such as ginseng and other
herbs, amino acids, vitamins, and co-enzyme-Q10
Be aware of caffeine content
some gels have as much caffeine as a half cup of coffee
may cause nervousness in those not accustomed to this
stimulant
37. Carbohydrate Gel Considerations
Most carb gel packs contain 100 calories,
and about 25 grams of carbohydrates
Consume one to three packets for every
hour of exercise
Goal -30 to 60 grams of carbohydrates per hour during
exercise lasting 60 minutes or more
Gels come in a variety of flavors
Take with four to eight ounces of water
Experiment with them PRIOR to the
event
38. Sports Beans (High Tech Jelly Beans)
The nutrient levels found in Sport Beans are
based upon established recommendations from
the American College of Sports Medicine (ACSM)
30 to 60 grams of carbohydrates per hour during
exercise lasting 60 minutes or more
Sport Beans provide a source of easily digestible
carbohydrate for fuel
Electrolytes sodium and potassium for proper
fluid balance
B1, B2, B3, and C vitamins for energy
metabolism
39. ACSM Guidelines for Fluids
ACSM guidelines also recommend drinking
fluid to prevent dehydration
1/4 to 3/4 cup of water every 15 to 20 minutes
and to include the electrolyte sodium and
potassium
40. Tips to Take With You
Start with a full tank
Begin your run well hydrated and
with adequate muscle fuel
(carbohydrate)
Try new products during training
sessions to determine what works
best for you
Consume fluids early and often
Refuel within 30 minutes post
exercise
