Westward Wuling Energy Gel Timing: 3 Key Points at Renzhiguan, Wushe, and Cuifeng

“Eating only when you feel tired” is a major mistake in Wuling fueling. Energy gels should be taken while you still have energy and your stomach can still absorb them. This article plans fueling timing around 3 landmarks on the Wuling route.

Estimated Energy Expenditure

Energy Expenditure for a 5-Hour Finish

• Total calorie expenditure: approximately 3,500-4,500 kcal
• Of which carbohydrates: approximately 60-70%
• Hourly carbohydrate expenditure: 60-90 g

Body’s Own Stores

• Muscle glycogen: 300-500 g (depending on training level)
• Liver glycogen: 80-100 g
• Total approximately 400-600 g, about 1,600-2,400 kcal

Conclusion: You Must Refuel Along the Way

A 5-hour effort requires 3,500-4,500 kcal, but the body only stores 1,600-2,400 kcal. Without refueling, you will “hit the wall” after about 2-3 hours.

Fueling Strategy: 60-90 g of Carbohydrates Per Hour

Energy Gel Content (approx. per packet)

• 20-25 g carbohydrates
• 80-100 kcal

Sports Drink (500 ml)

• 30-40 g carbohydrates
• 120-160 kcal

Energy Bar (1 bar)

• 25-40 g carbohydrates
• 150-250 kcal

Combination: At Least One Set Per Hour

• 1 energy gel + 500 ml sports drink = 50-65 g carbohydrates
• Or 1 energy bar + 500 ml water + a small amount of electrolytes

3 Key Fueling Points on Wuling (Landmarks with Timing)

Renzhiguan (16K, 830 m elevation, approx. 45-50 minutes)

• Status: Warm-up just finished, heart rate starting to rise
• Fueling:
  • 1 energy gel (25 g carbohydrates)
  • 250-300 ml sports drink
• Purpose: To store up for the steep climb before Wushe
• Note: Eat even if you’re not hungry; this is “pre-fueling”

Wushe (21K, 1,150 m elevation, approx. 1 hour 15 minutes)

• Status: 5 km of continuous climbing, heart rate in Z3
• Actions:
  • Stop for 3-5 minutes (7-Eleven available for water refill)
  • Eat solid food (energy bar, rice ball, banana)
  • Refill 500-750 ml of water
  • Use the restroom now if needed
• Purpose: To prepare for the long Wushe → Cuifeng section

Cuifeng (39K, 2,300 m elevation, approx. 3 hours 15 minutes)

• Status: The hardest section just finished, about to enter high altitude
• Fueling:
  • 1 energy gel (high-concentration, high-caffeine version)
  • 500 ml water refill
  • Eat 1 energy bar
• Purpose:
  • Store up before entering high altitude (above 2,300 m, gut absorption efficiency drops)
  • Caffeine to boost alertness for the final 16 km

Fueling Timeline for Each Section

Time	Distance	Fueling Content
0 min	0K	30 min before start: 1 banana + 250 ml sports drink
15 min	5K	A sip of water
30 min	10K	A sip of sports drink
45 min	16K	1 energy gel + 300 ml sports drink
60 min	19K	A sip of water
75 min	21K	Wushe major refuel (solid food, drink, restroom)
90 min	25K	A sip of sports drink
105 min	28K	1 energy gel
120 min	30K	A sip of water
135 min	33K	1 energy gel
150 min	35K	A sip of sports drink
165 min	37K	1 energy gel
195 min	39K	Cuifeng refuel (energy gel + water + energy bar)
210 min	42K	A sip of water
225 min	45K	1 energy gel
240 min	50K	A sip of water
255 min	53K	A small sip of sports drink (maintain from Kunyang to Wuling)
270 min	55K	Finish! Celebrate!

Energy Gel Types and Characteristics

Standard Energy Gels (GU, PowerBar)

• About 25 g carbohydrates, 100 kcal
• Suitable for: moderate intensity, non-critical moments

High-Concentration Hydrogels (Maurten 100)

• 25 g carbohydrates, gentler on the stomach
• No need to drink water with it
• Suitable for: all time periods

Caffeinated Energy Gels (GU Espresso Love, Maurten Gel 100 Caf 100)

• Contains 100 mg caffeine
• Recommended timing: Cuifeng (when 16 km remain)
• Note: 1 packet = 1 cup of coffee, don’t overdo it

Natural Food vs. Energy Gels

• Banana: moderate absorption, but bulky
• Honey stick: similar to energy gel
• Rice ball: suitable for a longer stop at Wushe
• Recommendation: Use energy gels (fast absorption) during the race, eat solid food at aid points

Gut Training

Why It’s Needed

• The gut is like a muscle; it needs training to absorb during exercise
• Without gut training, you may experience diarrhea or vomiting during the race

Training Method

• Practice taking energy gels on every long ride (> 2 hours)
• Consume 60-90 g of carbohydrates per hour
• Maintain for at least 6 weeks

Choose Your Brand

• Try multiple brands to find one that’s gut-friendly
• On race day, only use brands you’ve trained with

Caffeine Strategy

Caffeine Accelerates Glycogen Use and Boosts Alertness

• 3-6 mg per kg of body weight is the most effective dose
• For a 70 kg rider: 210-420 mg (total)

Timing

• One cup of coffee 30-60 minutes before the start (80-120 mg)
• Caffeinated energy gel at Cuifeng (100 mg)
• One more packet before Kunyang (100 mg)
• Total approximately 300-320 mg, suitable for most riders

Side Effects

• Heart palpitations, insomnia (don’t drink the night before)
• Diuretic effect
• Sensitive individuals should reduce the dose

Solid Food Choices (Eat at Aid Points)

Recommended

• Banana: classic, easy to digest, contains potassium
• Rice ball (salmon, grilled meat): long-lasting energy, a favorite among Taiwanese riders
• Energy bar (Clif Bar, PowerBar): convenient
• White toast + peanut butter: cheap and effective
• Chocolate (small amount): quick sugar + mood boost

Avoid

• High-fat foods (fried foods, pizza) → slow digestion
• High-fiber foods (avocado, vegetables) → gut stress
• Dairy products (unless you train with them) → possible lactose intolerance

Dealing with Discomfort

Upset Stomach

• Stop taking energy gels for 30 minutes
• Switch to diluted drinks (30% sports drink + 70% water)
• Eat something light and plain (white toast)

Nausea

• Stop and rest for 5 minutes
• Take deep breaths, sip small amounts of water
• Recover gradually

Hitting the Wall (Hypoglycemia)

• Immediately eat 2 energy gels + drink
• Rest for 10-15 minutes to let blood sugar recover
• Don’t push through it; you’ll feel much better after resting

Conclusion

Fueling is the hidden weapon of Wuling. A regular, precise, and well-practiced fueling rhythm allows your energy to be released steadily over 5 hours, avoiding the tragedy of hitting the wall. Don’t forget: what you eat isn’t for what you need now—it’s for what you’ll need 20 minutes from now.
