Cycling versus Running: How #FueledByFlow Athlete Austin Metz Adjusts his Strategy

When it comes to endurance sports like running and cycling, fueling your body adequately can make all the difference in performance and overall experience. Whether it's a short sprint or a long-distance event, the nutritional needs of your body vary between these two activities. Cyclist and runner Austin Metz delves into the nuanced fueling differences between running and cycling, drawing insights from his personal experiences and strategies that he has been refining over the years.

Running: The Under 10K Mark

For shorter running events, those under 10 kilometers, the fueling strategy takes a focused yet essential approach. Austin begins the day with a small, balanced breakfast consisting of an English muffin topped with peanut butter, honey, and banana. This combination provides the necessary carbohydrates for energy, healthy fats for sustained endurance, and a potassium-rich banana for muscle function. The race day strategy involves consuming 2 scoops of Flow 60/90 Endurance mix 30 minutes before the race starts. Since these events typically last around 30 to 45 minutes, no additional nutrition is taken during the race itself. This timing aligns well with the body's energy systems, providing a boost of energy without overwhelming the digestive system during the short event.

Running: Over 10K Mark

As the distances increase, the fueling strategy remains consistent with the small breakfast and the pre-race 2 scoops of Endurance mix. However, for events exceeding 10 kilometers, a more sophisticated approach is necessary. Austin incorporates a handheld bottle or a running vest with two bottles, each containing the 60/90 Endurance mix. When using a handheld bottle, the mix consists of 2 scoops of Endurance mix and 1 scoop of electrolyte mix. This blend supports sustained energy and replaces the electrolytes lost through sweat, helping to prevent cramping and maintain performance. For longer running events while wearing a running vest, Austin carries one bottle of electrolyte mix and one bottle of Endurance mix containing 2 scoops. This ensures a consistent supply of energy and hydration throughout the race.

Cycling: The Endurance Game

Cycling demands a slightly different approach to fueling due to the sustained effort and the mechanics of being on a bike. The breakfast strategy remains the same, offering a well-rounded foundation for the ride. During cycling events, Austin consumes 1 bottle with 2 scoops of Flow Endurance mix per hour. When the temperature rises above 80 degrees Fahrenheit, an additional scoop of electrolyte mix is added to the mix to counteract the increased fluid loss through sweat. This strategy has proven effective over Austin’s three years of cycling racing, highlighting the importance of personalized experimentation and adaptation.



Key Differences and Takeaways

The crux of the difference between the running and cycling strategies lies in the timing and quantity of fuel consumed. A typical endurance cycling event involves a sustained lower effort, the strategy revolves around 2 scoops per hour. On the other hand, running requires a slightly higher intake, with 1.5 to 2 scoops every 30 to 45 minutes. This disparity reflects the varying energy demands of these activities. The personal approach to refining the running strategy highlights the importance of trial and error. Running presents new challenges, and finding the optimal fueling plan takes time and experimentation. Austin’s willingness to adapt and test different strategies will likely lead to a better understanding of what works best for his running endeavors.

Fueling strategies for running and cycling are not one-size-fits-all approaches. Austin’s insights emphasize the significance of understanding your body's needs, testing different methods, and ultimately finding a strategy that maximizes performance and enjoyment. Whether you're tackling a 10K run or embarking on a long cycling journey, the right fuel can be the key to unlocking your true potential.
