Natural vs Engineered Fuel: Maple Syrup, Waffles, and Beyond
From maple syrup pouches to high-tech hydrogel formulas, runners have more fueling choices than ever. Should you go natural or engineered? Let's compare.
What is “Natural Fuel”?
Natural fuel options derive from whole foods and recognizable ingredients. These include products like UnTapped Energy Gel, made from maple syrup, and UnTapped Waffle, a carb-rich snack. They appeal for their simple carbs and natural taste.
Pros:
Recognizable ingredients
Delicious taste
Simple carbohydrate source
Cons:
Bulkier packaging
Variable carb and sodium content
Natural fuels are excellent for runners who prioritize taste and simplicity, often preferred for shorter races or less intense training days.
What is “Engineered Fuel”?
Engineered fuels like Maurten Gel 100, GU Energy Gel, and NeverSecond C30 are crafted for precision. They offer controlled carbohydrate ratios, often with added electrolytes and caffeine for endurance.
Pros:
Precision formulas
Predictable absorption
Added electrolytes and caffeine
Cons:
Synthetic taste for some
Higher cost
Engineered fuels are ideal for long races or high-intensity conditions, providing consistent energy and hydration support.
Digestibility & Performance
The choice between natural and engineered fuels also depends on digestibility and performance needs.
Natural fuels provide quick carbs but may lack controlled sodium and caffeine.
Engineered fuels offer predictable absorption, reducing the risk of GI distress during long or intense runs.
GI Distress Factors
Simple sugars in natural fuels can be gentler on the stomach for some, while engineered blends are designed to minimize digestive issues.
