LA MARATHON BLUEBRINT ℠
Measures how your body performs at race effort, defining sustainable pace, heart rate, carbohydrate utilization, and fuel requirements.
Marathon performance is constrained by sustainable intensity and available fuel. Small pacing errors early in the race can disproportionately increase carbohydrate burn, accelerating fatigue and increasing the likelihood of late-race collapse.
Measuring your physiological response at race-relevant intensities removes the guesswork from pacing and fueling. It defines what you can actually hold, how much carbohydrate is required to support it, and what happens when intensity exceeds sustainable limits, ensuring race execution aligns with physiology rather than optimism.
