Training Strategy for the King of the Mountain Challenge: A Complete Plan from W/kg to Climbing Pace

In Taiwan’s cycling community, “riding up Wuling” is a milestone, and achieving a good result in the KOM King of the Mountain Challenge is the ultimate goal for many riders. From the Puli Geographic Center Monument to Wuling (elevation 3,275m), 55 kilometers with 2,750 meters of climbing—this is not a challenge that can be completed “by feel.” You need precise numbers, scientific training, and a well-thought-out pacing plan.

W/kg: The Core Metric for the King of the Mountain

Why is W/kg More Important Than Absolute Watts?

On flat roads, an 80 kg rider producing 280W and a 60 kg rider producing 280W will travel at nearly the same speed (air resistance dominates). But on gradients above 7%, gravity accounts for more than 80% of the resistance—at this point, power-to-weight ratio (W/kg) is the key determinant of speed.

Estimated Wuling Times for Different W/kg Levels

Calculation method: Estimated based on 55km with 2,750m of climbing, accounting for gradient changes and altitude effects. Actual results are affected by weather, wind direction, and road conditions.

Two Paths to Improving W/kg: Increase W or Decrease kg

Path One: Increase Power (Increase the Numerator)

12-Week FTP Improvement Plan:

Phase 1: Aerobic Base (Weeks 1-4)

Monday: Rest
Tuesday: Sweet Spot 2 × 20 minutes @ 88-93% FTP, 5 minutes rest
Wednesday: Zone 2 ride 1.5 hours
Thursday: VO2max intervals 5 × 4 minutes @ 106-110% FTP, 4 minutes rest
Friday: Rest or core training
Saturday: Long climbing ride 3-4 hours
Sunday: Recovery ride 1 hour

Phase 2: Threshold Strengthening (Weeks 5-8)

Tuesday: Threshold 3 × 15 minutes @ 95-100% FTP, 5 minutes rest
Thursday: VO2max 6 × 4 minutes @ 108-112% FTP, 3.5 minutes rest
Saturday: Long-distance simulation (including tempo riding segments) 3.5-4.5 hours
  Including: 2 × 30 minutes @ 85-90% FTP climbing segments

Phase 3: Specificity (Weeks 9-11)

Tuesday: Over-Under 3 × 12 minutes
  (2 minutes @ 105% FTP + 2 minutes @ 90% FTP, repeated 3 times = 12 minutes)
  5 minutes rest
Thursday: Long intervals 3 × 8 minutes @ 100-105% FTP uphill
Saturday: Wuling simulation ride or half-course test

Phase 4: Taper (Week 12)

Training volume reduced by 40-50%
Keep 1-2 high-intensity sessions but shortened
Get plenty of rest, focus on nutrition and sleep

Path Two: Lose Weight (Decrease the Denominator)

For most riders, losing weight is the fastest way to improve W/kg. But it must be done carefully:

Key principles:

1. Weight loss should only occur during the "base period" and "early build period"
2. Stop losing weight 4-6 weeks before the race; switch to maintenance or slight increase
3. Daily protein intake no less than 1.6g/kg (to prevent muscle loss)
4. Do not reduce carbohydrate intake on high training volume days
5. Goal: reach race weight on event day

Practical Example of W/kg Improvement

Rider A: 75kg, FTP 250W → W/kg = 3.33
Goal: W/kg 4.0

Path 1 (pure power increase): Need FTP 300W (+50W, difficult)
Path 2 (pure weight loss): Need to drop to 62.5kg (-12.5kg, unrealistic)
Path 3 (combination): FTP 270W + weight 68kg → W/kg = 3.97 ✅
  Power increase of 20W (feasible) + weight loss of 7kg (progressive over 3-4 months)

Wuling Segment Pacing Strategy

Course Analysis

Effect of Altitude on Power

This is a key factor many cyclists overlook:

Practical Implication: If your sea-level FTP is 250W, your effective FTP at the summit of Wuling is approximately 200W. Your pacing must account for this diminishing effect!

Pacing Calculation Tool

Step 1: Determine your sea-level FTP (e.g., 250W)
Step 2: Calculate altitude-adjusted FTP for each segment
Step 3: Target 75-85% of adjusted FTP as your goal power
Step 4: Use bestbikesplit.com or similar tools to simulate

Example (FTP 250W, 70kg):
  Wushe (1,150m): Target 182-195W
  Cingjing (1,750m): Target 175-188W
  Cuifeng (2,300m): Target 165-178W
  Yuanfeng (2,750m): Target 155-168W
  Wuling (3,275m): Target 145-160W

Training Strategies for Other Taiwan KOM Routes

Hehuan Mountain (Dayuling → Wuling)

Distance: Approximately 18 km
Elevation Gain: Approximately 1,000m
Starting Altitude: 2,565m (Already at high altitude)
Characteristics: Entire route above 2,500m, significant oxygen impact
Pacing: Reduce power by 15-20% compared to sea-level FTP
Time Goal (3.5 W/kg): Approximately 70-80 minutes

Tataka (New Central Cross-Island Highway)

Distance: Approximately 90 km (Shuili → Tataka)
Elevation Gain: Approximately 2,400m
Highest Altitude: 2,610m
Characteristics: Long distance, gentle gradient in the first half, steep in the second half
Pacing: Conservative for the first 50K (65-70% FTP), steady acceleration for the final 40K
Time Goal (3.5 W/kg): Approximately 3.5-4 hours

High-Altitude Acclimatization Strategies

If the race is held at high altitude (such as KOM), early acclimatization is important:

Option 1: Arrive Early at Altitude (Most Effective)

5-7 days before the race: Arrive at 1,500-2,000m altitude
Activity: Easy riding 30-60 minutes daily
Accommodation: Stay at high altitude whenever possible (Cingjing, Hehuan Mountain Lodge)
Note: Mild altitude sickness in the first 2 days is normal

Option 2: Arrive Early on Race Day

If you cannot arrive early at altitude:
  Arrive at the start 2-3 hours before the race
  Do 15-20 minutes of light warm-up
  Allow your body to begin adapting to the lower oxygen partial pressure

Option 3: Simulated High-Altitude Training

Use a high-altitude training mask (limited effectiveness, but better than nothing)
Or deliberately reduce ventilation on the trainer
Note: Scientific evidence on the effectiveness of high-altitude masks is inconclusive

Race Day Practical Checklist

3 days before the race:
  □ Carbohydrate loading (increase carbs by 30% per meal)
  □ Reduce fiber intake (avoid gastrointestinal issues)
  □ Get adequate sleep (8-9 hours)
  □ Confirm vehicle and equipment

1 day before the race:
  □ 30-minute easy ride + 2-3 x 30-second leg openers
  □ Normal breakfast, carb-focused lunch, easily digestible dinner
  □ Prepare race nutrition
  □ Lights out by 23:00

Race morning:
  □ Eat breakfast after waking up (3 hours before the start)
  □ Breakfast: White rice/bread + jam + banana + coffee
  □ Warm up for 15-20 minutes (including 2 x 1-minute progressive accelerations)
  □ 15 minutes before the start: 1 energy gel + water

During the race:
  □ One energy gel every 30-40 minutes
  □ Drink water every 15-20 minutes
  □ Add caffeinated gels after Cuifeng (if needed)

Conclusion

The King of the Mountain challenge is a perfect combination of science and willpower. You need to know your W/kg precisely, understand the effect of altitude on power, develop a sensible pacing strategy, and then execute the plan on race day. Don’t get carried away by the excitement at the starting line—any debt you incur in the first half will be collected with interest in the second half.

The Most Important Pacing Principle: If you feel “too easy” at Wushe, your pacing is just right. If you feel “comfortable and fast” at Wushe, you’re already going too hard.
