Power Requirements on Taiwan's KOM Routes: A Comparison of Yangjin Highway vs. Eastward Wuling Ascent

Introduction

Taiwan is a paradise for cycling climbers in Asia, boasting a density of high mountain segments rarely seen anywhere else in the world. Among them, the Yangmingshan KOM segment on Yangjin Highway and the Hehuan Mountain Road on the Wuling East Ascent are the two power challenges most coveted by Taiwan’s amateur riders.

These two routes differ fundamentally in distance, gradient, elevation, and energy demands, requiring completely different training strategies. This article will analyze both routes in depth from a power perspective, making your race preparation more targeted.

Basic Route Information Comparison

Power Characteristics of Yangjin Highway (Provincial Highway 2A)

Segment Gradient Analysis

The climbing characteristic of Yangjin Highway is “short and fierce”—within the 8 km climb, there are multiple steep sections exceeding 10% gradient, especially the S-curves near the overpass. This type of short-duration, high-intensity climbing places a far greater demand on VO2max power than long-distance endurance.

Power Recommendations by Section:

Key Training Focus

To perform well on the Yangjin KOM, the critical ability is 20–40 minutes of high-intensity sustained power, corresponding to 105–115% of FTP:

• VO2max Intervals: 5×5 minutes @ 110% FTP, 1–2 times per week
• Threshold Training: 2×20 minutes @ 95–100% FTP
• Full Yangjin Simulation: At least one all-out time trial per month, recording power for each section

Ideal W/kg (20-minute Maximal Power):

• Finish (< 40 minutes): > 4.0 W/kg
• Competitive (< 33 minutes): > 4.8 W/kg
• Top Tier (< 28 minutes): > 5.5 W/kg

Power Characteristics of Wuling East Ascent (Provincial Highway 14A)

Segment Gradient Analysis

The climbing characteristic of the Wuling East Ascent is “long and steady”—over the 48 km climb from Wushe to Wuling, the average gradient is only 4.4%, but the prolonged sustained output is an immense test of the aerobic system. The hypoxic effect at high altitude (above 2,500 meters) further makes the actual physiological load far exceed what the power numbers indicate.

Power Recommendations by Section:

Key Training Focus

The core challenge of the Wuling East Ascent is long-duration aerobic endurance below threshold, along with adaptation to the high-altitude environment:

• Zone 2 Long Rides: At least one 3–4 hour Zone 2 ride per week
• Sweet Spot Accumulation: 2×30 minutes or 3×20 minutes @ 88–93% FTP
• Long Climb Simulation: One month before Wuling, schedule 2–3 complete Cingjing–Wuling segment simulations

Ideal W/kg (1–2 Hour Sustained Power):

• Finish (< 4 hours): > 4.5 W/kg
• Good Amateur Result (< 3 hours): > 5.0 W/kg
• Top Amateur (< 2.5 hours): > 5.5 W/kg

Training Demand Comparison of Both Routes

Strategy for Preparing for Both Goals Simultaneously

If you want to achieve good results in both the Yangjin KOM and the Wuling East Ascent, your training focus should be Wuling as the priority, Yangjin as secondary, because the aerobic foundation required for Wuling underpins Yangjin performance, but the reverse does not hold.

Suggested Weekly Schedule (6 hours/week for amateur riders):

• Tuesday: VO2max Intervals (60 minutes) ← Yangjin preparation
• Thursday: Sweet Spot (75 minutes) ← General
• Saturday: Long Zone 2 Ride (3 hours) ← Wuling preparation
• Sunday: Yangjin KOM Simulation (1-hour time trial) ← Yangjin testing

Practical Advice

1. First confirm the characteristics of your target route: Choose the route you most want to break through on as your “A-level goal” and design your primary training around it
2. Find simulation routes locally in Taiwan: For Yangjin preparation, use Yangmingshan’s Datun Mountain and Liuhuang Valley sections; for Wuling, use the Pinglin section of the Beiyi Highway for long climb simulation
3. Use Strava Segments to track progress: Both the Yangjin KOM and Wuling East Ascent have official segments on Strava, allowing direct comparison of historical results
4. Note the altitude compensation for power: Power estimates at Wuling’s 3,275m elevation need to be multiplied by an altitude correction factor (approximately 0.8–0.85)
5. A full pre-race simulation is essential: Perform at least one complete simulation 4–6 weeks before the race to identify flaws in your pacing strategy

Conclusion

The brief explosiveness of Yangjin Highway and the prolonged exertion of the Wuling East Ascent represent the two extremes of road cycling climbing challenges in Taiwan. Understanding the power demands of each route gives your race preparation a clear physiological basis. Whether your goal is to smash your personal best at Fengguizui or to witness the sunset at the summit of Wuling, power training can help you achieve it with greater precision. Taiwan’s mountains await you—conquer them with the right pedal stroke.
