The Benefits of Altitude Training for Cyclists: Taiwan's Wuling as a Natural Advantage

Introduction

Altitude training is an important method for elite endurance athletes to enhance performance. The higher the altitude, the lower the oxygen concentration in the air. To cope with the hypoxic environment, the body initiates a series of physiological adaptation mechanisms, the most critical of which is increased secretion of erythropoietin (EPO), which in turn promotes red blood cell production and enhances the blood’s oxygen-carrying capacity. Taiwan boasts Wuling, the highest highway in the country (3,275 meters above sea level), offering amateur cyclists a natural advantage for altitude training.

The Physiological Mechanisms of Altitude Training

When the body is exposed to a hypoxic environment (typically above 2,000 meters), the following physiological responses gradually occur:

Short-term (1–3 days):

• Breathing becomes faster and deeper; heart rate increases
• Plasma volume decreases (appearing as higher hemoglobin concentration, but this is hemoconcentration rather than a true increase)
• Athletic performance temporarily declines

Medium-term (1–2 weeks):

• Renal EPO secretion increases
• Red blood cell production begins to accelerate
• Gradual adaptation to the hypoxic environment; exercise capacity partially recovers

Long-term (after 3–4 weeks):

• Red blood cell count and hemoglobin concentration truly increase
• Oxygen-carrying capacity per unit of blood rises
• The “altitude effect” persists for 2–4 weeks after returning to sea level

The “Live High, Train Low” Strategy

This is currently the most research-supported altitude training model. The principle is: sleep and live at high altitude to stimulate EPO and red blood cell production, while training at low altitude to maintain training quality.

At high altitude, training intensity is limited by hypoxia; if you force high-intensity training at altitude, training quality actually declines. Therefore, elite cyclists often descend during the day to altitudes below 1,000m for high-intensity training, then return to sleep at altitudes above 2,500m at night.

Practical applications in Taiwan:

• Stay at Cingjing Farm (1,750m) or Hehuanshan Lodge (2,600m)
• Perform threshold training in the early morning on the Wushe to Lushan section (900–1,200m)
• Do easy aerobic riding in the afternoon on the Cingjing to Hehuanshan section (1,750–3,200m)

Practical Recommendations for Altitude Training at Taiwan’s Wuling

Recommendations for amateur cyclists trying altitude training for the first time:

• First acclimatize for 1–2 nights at Hehuanshan Lodge (approximately 2,600m)
• Reduce training intensity for the first 2 days to let the body adapt to hypoxia
• From day 3 onward, you can attempt easy climbing training
• Watch for symptoms of acute mountain sickness (headache, nausea, insomnia)

Prevention of acute mountain sickness:

• Do not ascend too quickly; let the body adapt gradually
• Stay well hydrated (accelerated breathing at altitude increases fluid loss)
• Avoid alcohol (it worsens altitude reactions)
• If a headache occurs, acetaminophen can provide relief; if symptoms worsen, descend immediately

Timing Your Altitude Training

The effects of altitude training are typically most pronounced 2–3 weeks after returning to sea level. Therefore, it should be scheduled 3–4 weeks before your target event, so the EPO effect peaks on race day.

Practical Advice

• Amateur cyclists do not need long-term altitude training; 1–2 sessions of 7–14 days at Hehuanshan per year already yield significant benefits
• Taiwan’s Cingjing Farm, Wuling, and Lishan are all excellent bases for altitude training, with relatively convenient access
• During altitude training, you should supplement 20–30% more iron than at sea level (red blood cell production requires iron); consult a sports nutritionist

Conclusion

Taiwan is one of the few places where amateur cyclists can easily access altitude training conditions—Wuling’s 3,275-meter elevation is an ideal height for boosting red blood cell production. Leverage this natural advantage, combined with a scientific training plan, and your aerobic capacity will improve far faster than that of cyclists who train only at sea level.
