Fueling Endurance Athletes
by Beth Wolfgram MS, RD, CSSD, CSCS
Triathletes, trail runners, long distance cyclists, cross-country skiers, and rowers all fall into the category of endurance athletes. These sports demand long durations of activity, as well as fueling and recovery challenges. Endurance athletes want to stay fueled for their sport, decrease their risk of injury, and recover so they can come back for more training. Here are some factors to consider when making a fueling plan for endurance activities:
TYPE OF ACTIVITY
The type of activity has a large impact on an athlete’s body endurance and what wise and feasible fuel (food) the body should consume. For example, if the athlete hikes for 4 hours it is easy to carry water and snacks like a sandwich, trail mix with pistachios, dried fruit, and energy bars. But if the athlete is doing a long-distance, open-water swim, it would be harder to consume fuel while in the water. Athletes may need to rely more on sports drinks or products like gels and chews. Choosing tolerable and appealing fuel is essential!

DURATION OF ACTIVITY
The length of time of an endurance activity will determine how much fuel an athlete needs. A 100-mile bike ride requires more carbohydrates and fluids than a casual pedal around the neighborhood for an hour. Athletes need to be well fueled for short-duration activity, but the longer they train, the more important nutrition is!
Although fueling needs are high, many endurance athletes find their appetite can be suppressed when doing long duration activity. Finding tasty fuel sources that provide much-needed carbohydrates and electrolytes is ideal. Some great options include peanut butter and jelly sandwiches, squeezable applesauce pouches and salty snacks like pretzels.
The current sports nutrition recommendations* for activities longer than 60-90 minutes are:
30-90 grams of carbohydrates per hour. Options include sports drinks, gels, chews, bars or whole food like homemade energy bites, sandwiches (cut in quarters to make it easier to eat), crackers, bagels, bananas, etc.
Sufficient fluids to replace sweat losses. This varies from athlete to athlete, but a good rule of thumb is4–8 ounces every 15 to 20 minutes.
INTENSITY OF ACTIVITY
When planning for an athlete’s fueling needs, consider how hard they will be working. Are they doing a cross-country ski at a moderate pace, or will they be trail running with a great deal of climbing? The harder they work, the more they will need to focus on food and fluid needs.
Every athlete has different likes and dislikes. Finding what works for each athlete is so important! Some athletes like to use traditional sports products, and some enjoy foods like gummy bears, crackers, or potatoes to get their carbohydrate needs met. Having something to look forward to can be a huge mental boost to an athlete who is out on a hard training session. Everyone has their own little tricks that work for them, and it is important to experiment with fueling during training (not on the day of an event).
