Most athletes don't fail in training because they're not fit enough. They fail because they're not fueled enough. That's the core idea behind the 1-1-2-3 Method — a simple fueling framework developed by Greg Mueller, High Performance Director at Podium Racing and one of the most credentialed triathlon coaches in the country.
I developed the 1-1-2-3 Concept after noticing a recurring theme in the endurance community: most failed sessions aren't due to a lack of fitness, but a lack of fuel.
Between the "noise" on social media and the complex ratios floating around, fueling has become unnecessarily over-engineered. While I'm not a certified nutritionist, I am a coach and athlete who has observed what actually moves the needle. This is a generalized, non-dogmatic framework designed to keep you hydrated, recovered, and energized.
The Formula
1: One Ounce of Water per pound of body weight daily (baseline, excluding workout hydration).
1: One Gram of Protein per pound of body weight daily.
2: Divide Weight by Two for Carbs per hour. Take body weight in lbs, divide by two, and that's your goal per hour for grams of carbs (For sessions exceeding 75 minutes).
3: Three Hours of Rest (minimum) between sessions if one is intense or exceeds 60 minutes.
How it looks in Practice
If you weigh 150 lbs, your daily targets would look like this:
Pillar | Daily Target (150lb Athlete) | Pro Tip |
Hydration | 150 oz water | Drink one ounce per pound daily. |
Protein | 150g protein | |
Fueling | Lbs ÷ 2 = carbs/hr e.g. 150lbs ÷ 2 = 75g/hr | Maurten Drink Mix is recommended for high-carb intake. |
Recovery | 3-Hour Gap | Wait at least 3 hours between intense sessions. |
Why This Works
This isn't meant to be a medical prescription, and it may not fit those with specific metabolic challenges. However, for the average athlete, it removes the guesswork. If you hit these four markers, you will likely find that you feel significantly better both during your sessions and—more importantly—during the recovery hours that follow.
How does this 1-1-2-3 framework compare to the fueling strategy you're currently using?
