Climbing Endurance Training: Sustained Output on Long Climbs and Cardiorespiratory Adaptation

Introduction

Taiwan’s terrain is highly mountainous, from Yangmingshan in the north, Wuling in Nantou, to Taipingshan in Yilan—there are excellent climbing training grounds everywhere. However, many riders simply “push through” climbs without clear intensity targets, ending each climb feeling tired but unsure whether they are actually improving. This article will explain the core principles and systematic methods of long-climb endurance training from a sports physiology perspective.

The Physiological Demands of Climbing

The main differences between climbing and riding on flat terrain are:

• Gravity does a larger share of the work: The steeper the gradient, the higher the power required to overcome gravity, and here the advantage of being lightweight becomes apparent
• Cadence usually drops: As gradient increases, many riders’ cadence falls to 60–70 RPM, increasing muscular load
• Higher heart rate: At the same power output, heart rate during climbing is often 5–10 bpm higher than on flat roads (related to posture and breathing)
• Concentrated energy expenditure: There is no downhill momentum to recover with, requiring sustained output

Core Methods for Long-Climb Endurance Training

Sustained Climbing is the most basic form of climbing training. Choose a continuous uphill section of 20–60 minutes and maintain an even output at Sweet Spot (88–93% FTP) or threshold intensity (95–105% FTP). Suitable sections in Taiwan include:

• Beiyi Highway (Pinglin toward Yilan direction): approximately 30–40 minutes of continuous climbing
• Wuling East Approach (Wushe toward Wuling): an ultra-long climb of over 2 hours, suitable for aerobic endurance training
• Lixing Industrial Road: approximately 50 minutes of high-intensity climbing, suitable for threshold training

Climbing Repeats: Choose an uphill section of 8–15 minutes, ride it 3–5 times at near-threshold intensity, recovering on the descent between sets. This method has high training density and suits riders with limited time.

Cadence Variation Training: On the same climb, do the first rep at low cadence (60–65 RPM) with heavy pedaling to train strength, and the second rep at high cadence (80–85 RPM) with light pedaling to train cardiorespiratory efficiency, feeling the difference between the two approaches.

Timeline of Cardiorespiratory Adaptations to Climbing

• Weeks 1–4: Neuromuscular adaptation, improved movement efficiency, feeling slightly less effortful
• Weeks 4–8: Increased mitochondrial density, improved lactate clearance
• Weeks 8–12: Improved cardiac output, noticeable progress in average climbing speed
• Months 3–6: Overall climbing ability improves comprehensively, able to sustain higher power for longer periods

Common Climbing Training Mistakes

• Starting too fast: Many riders go all-out at the start of a climb, causing cadence to collapse in the latter half, with heart rate spiking while power drops
• Using only one cadence: A fixed cadence makes the training stimulus too monotonous; it should be varied regularly
• Neglecting recovery: Adequate recovery is needed after climbing training; several consecutive days of hard climbs can lead to overtraining
• Pacing by feel: The gradient changes on Taiwan’s mountain roads are large, making it difficult to control intensity by feel alone; a power meter is the most valuable tool for climbing training

Practical Advice

• Use a power meter to set pacing targets, using watts rather than speed as the intensity indicator (speed is too heavily affected by gradient and wind)
• Ensure adequate carbohydrate intake before climbing; during long climbs, replenish with energy gels or bananas every 45–60 minutes
• Pay special attention to hydration when climbing in Taiwan’s summer; although temperatures are lower in higher-altitude mountain areas, sweat loss is still significant
• In the 2–3 weeks before a race, switch your training climbs to gradients matching the target course for specific training

Conclusion

Taiwan’s mountains are the best training grounds, but getting real benefit from riding them requires a scientific approach. Choose the right intensity, control your pacing, and record your data—make every climb a stepping stone to fitness improvement, not just a memory of suffering.
