2:1 vs 1:1 Proto: Which TORQ Fueling System Is Right for You?
Choosing the right fueling strategy matters just as much as your training. TORQ offers two carbohydrate systems designed for different athletes and different intake targets:
- 2:1 Range = best for most athletes fueling at 30–90g carbs per hour
- 1:1 Proto Range = designed for athletes targeting 120g+ carbs per hour
Both can be highly effective when used correctly. The key is choosing the right tool for your goals.
Why Carbohydrate Fueling Matters
Your body stores carbohydrate as glycogen in the muscles and liver. During endurance exercise, those stores become limited.
Taking carbohydrate during exercise can help:
- preserve glycogen stores
- maintain pace and power
- delay fatigue
- support concentration
- improve late-race performance
In simple terms: better fueling often means better performance.
Understanding 2:1 and 1:1 Ratios
TORQ uses blends of:
- Maltodextrin (glucose source)
- Fructose
These carbohydrates use different transporters in the gut:
- Glucose uses SGLT1
- Fructose uses GLUT5
Using both pathways allows higher total carbohydrate absorption than glucose alone.
Why 2:1 Still Works So Well
TORQ’s classic 2:1 system remains the best option for most endurance athletes.
Best For:
- 30–90g carbs per hour
- runners
- triathletes
- cyclists
- everyday training
- athletes new to fueling
Why:
At 90g/hr, a 2:1 ratio provides:
This fits well with how most athletes absorb carbs.
Bottom Line:
If you are fueling below 90g/hr, 2:1 is usually the smarter and more flexible choice.
When 1:1 Proto Makes Sense
The 1:1 Proto range is designed for athletes chasing very high carb intakes.
Best For:
- 120g+ carbs per hour
- Ironman bike legs
- elite racing
- long road cycling events
- highly trained endurance athletes
At 120g/hr, a 1:1 ratio gives:
This allows greater use of both transport systems.
Important Warning: 1:1 Is Not for Everyone
If you are not targeting 120g+ per hour, 1:1 may not be ideal.
At lower intakes:
- glucose delivery may be suboptimal
- fructose proportion is higher
- GI issues may increase for some athletes
Bottom Line:
1:1 is a performance tool for athletes committed to high intakes.
Bike vs Run: Why This Matters
Many athletes tolerate higher carbs on the bike than the run.
On the Bike:
Often possible to take 90–120g/hr because:
- less impact
- easier to sip regularly
- steadier effort
- better cooling airflow
On the Run:
Often easier to tolerate 60–90g/hr because running adds:
- stomach bounce
- heat stress
- higher GI risk
- pace surges
Smart Triathlon Strategy:
- Bike: higher carb intake
- Run: slightly lower intake
How to Progress from 90g to 120g
If you already tolerate 90g/hr on 2:1, you can gradually build higher.
Best Approach:
Use a blend of:
- 2:1 products
- 1:1 Proto products
This helps increase total carbs while keeping glucose delivery strong.
Gut Training Matters
Your gut adapts with practice.
Just like muscles respond to training, your digestive system can improve tolerance to carbs over time.
Build Gradually:
- 60g/hr
- 75g/hr
- 90g/hr
- 100g/hr
- 120g/hr (if needed)
Always test in training before race day.
TORQ 1:1 Proto Made Simple
Each product provides 40g carbohydrate.
1 ATU = 40g carbs
Examples:
To reach 120g/hr:
Take 3 ATUs per hour
Mix drinks and gels depending conditions:
Hot weather:
More drink
Cool weather:
More gels
Which One Is Right for You?
Choose 2:1 If:
- you fuel below 90g/hr
- you race running events
- you’re newer to fueling
- you want flexibility
Choose 1:1 Proto If:
- you want 120g+/hr
- you’ve trained your gut
- you race long cycling / triathlon events
- you want maximum intake potential
Final Word
For most athletes, 2:1 remains the best starting point.
For advanced athletes pushing elite-level carbohydrate targets, 1:1 Proto opens the door to 120g+ per hour.
The best strategy is not the highest number — it’s the one you can absorb, tolerate, and repeat consistently.
