Understanding CLIF BLOKS for Fueling
CLIF BLOKS are a semi-solid, easy-to-chew source of carbohydrates designed to provide quick fuel for endurance athletes. Unlike a full energy bar that requires significant digestion, bloks are absorbed more rapidly, making them an ideal choice during intense activity when solid food is less palatable or harder to process.
Why Carbohydrates are Key
During exercise, your body uses glycogen (stored carbohydrates) for energy. The harder you work, the faster these stores are depleted. Consuming easily digestible carbohydrates like those in CLIF BLOKS helps maintain your blood sugar and energy levels, allowing you to sustain your performance for a longer duration.
The Recommended CLIF BLOKS Fueling Schedule
Optimal intake of CLIF BLOKS depends on the timing relative to your activity. A standard packet contains six chews, and general guidelines suggest consuming one to two packets per hour during sustained exercise.
Pre-Activity Intake
To top off your glycogen stores and increase blood sugar levels before a workout, consider having half a packet (three chews) about 15 minutes before you begin. This provides a quick energy boost without overburdening your stomach.
During-Activity Fueling
For activities lasting more than an hour, maintaining a consistent fueling schedule is crucial. The standard recommendation is to consume 3 to 6 bloks per hour, depending on your energy needs and the intensity of your exercise.
- For moderate intensity: Aim for 3 bloks every 20-30 minutes.
- For high intensity: Increase your intake to 4-6 bloks per hour, possibly spaced out more frequently, such as 2 bloks every 20 minutes.
Important: Always chase your bloks with a drink of water. This is vital for proper digestion and to support adequate hydration, especially since the rapid carbohydrate intake can draw water into your stomach during digestion.
Customizing Your Intake Based on Intensity and Environment
Your fueling plan should adapt to your specific situation. Here's how to customize your CLIF BLOKS usage:
- High Intensity: During races or peak effort, you might need to lean towards the higher end of the recommended intake. The quick-access carbs in bloks are essential when your body is under stress.
- Heavy Sweating: Flavors like Salted Watermelon and Margarita contain extra sodium to help replenish electrolytes lost through sweat. Consider these options during hot, humid conditions or if you are a heavy sweater.
- Needing a Boost: Certain flavors, such as Black Cherry, Tropical Punch, and Orange, contain caffeine derived from green tea extract. These can provide a mental and physical boost for that final push, but be mindful of your overall caffeine intake.
Comparison of Fueling Options
Knowing the differences between fuel types can help you plan your nutrition strategy. The following table compares CLIF BLOKS to gels and energy bars.
| Feature | CLIF BLOKS | Energy Gels | Energy Bars |
|---|---|---|---|
| Texture | Semi-solid, easy-to-chew | Liquid, gel-like | Solid, requires chewing |
| Absorption Speed | Fast, quicker than a bar | Very fast | Slower, requires digestion |
| Energy Release | Quick burst | Instantaneous burst | Slower, sustained release |
| Electrolytes | Added sodium/potassium in some flavors | Included in some formulations | Minimal to moderate |
| Packaging | Resealable Fastpak for easy access | Tear-open sachet | Wrapper |
| Water Required? | Yes, always chase with water | Some require water, others don't | Yes, aids digestion |
| Portability | Excellent, fits in pockets | Excellent, compact | Good, can be bulky |
Best Practices for Consuming CLIF BLOKS
Here are some key tips to ensure you get the most out of your CLIF BLOKS and avoid stomach upset:
- Start Early: Don't wait until you feel fatigued. Start your fueling regimen within the first hour of a long or intense workout to stay ahead of your energy demands.
- Practice on Training Runs: Never try a new fueling strategy on race day. Practice with your CLIF BLOKS during training to figure out what works best for your body and to avoid any surprises.
- Stay Hydrated: Dehydration can impair carbohydrate absorption. Always drink plenty of water when consuming your chews, especially during warmer weather.
- Listen to Your Body: If you feel stomach discomfort, reduce your intake or switch to a different fuel source temporarily. Your body's needs can vary based on many factors.
- Mix and Match: Use bloks for a quick hit of energy, but consider supplementing with other fuel sources, like a bar for a slower energy release or a hydration mix for electrolytes.
Conclusion
For endurance athletes, understanding how often to eat CLIF BLOKS is key to maintaining peak performance. The general recommendation is to consume 3 to 6 chews per hour during activity, accompanied by water. However, tailoring this frequency based on your workout's intensity, the environmental conditions, and your personal needs is what will truly optimize your fueling strategy. By practicing with different timings and varieties during training, you can create a reliable nutrition plan that keeps you energized from start to finish.
