Training Adjustments for Older Riders: How to Maintain and Improve Cycling Performance After 40

For road cycling enthusiasts in Taiwan, whether you’re tackling the long climbs around the Hsuehshan Tunnel or attacking the switchbacks of the Central Cross-Island Highway on weekends, the degree of scientific training often determines whether you can break your personal best (PB). This article will take a systematic, actionable approach to help you deeply understand the sports science behind “training adjustments for older riders,” combined with Taiwan’s local riding environment, events (such as the Taiwan KOM Challenge), and climate conditions, to provide a training mindset that can truly be put into practice.

A common blind spot for many cyclists is equating “being tired” with “being effective.” In reality, performance improvement comes from the complete cycle of Stimulus → Fatigue → Recovery → Supercompensation. If you simply accumulate fatigue without structured intensity distribution and recovery planning, your body will remain in a state of fatigue buildup, ultimately leading to stagnation or even decline in performance. The goal of this article is to help you build a training framework where you “know why you’re training this way.”

Next, we’ll start with the physiological mechanisms, gradually moving into actual workout plans, data interpretation, Taiwan route applications, common mistakes, and long-term planning—content that is solid and can be directly applied to your next training cycle.

1. The Underlying Exercise Physiology

To understand any cycling training method, you must first return to the body’s three major energy systems:

For the vast majority of Taiwanese cyclists, long climbs around the Hsuehshan Tunnel that take one to two hours are dominated by the aerobic system. This is why the “Aerobic Base” is considered the foundation of the training pyramid—without a solid aerobic engine, even the strongest anaerobic capacity is merely a flash in the pan.

At the cellular level, long-term aerobic training brings several key adaptations:

• Increased mitochondrial density and volume: Mitochondria are the power plants of cells; the more there are, the more ATP can be produced per unit of time.
• Capillarization: A denser network of capillaries around muscles improves oxygen and nutrient delivery efficiency and speeds up metabolic waste clearance.
• Increased Stroke Volume: The amount of blood pumped per heartbeat increases, which lowers resting heart rate—this is why well-trained cyclists often have morning heart rates in the 40s.
• Rightward shift of the Lactate Threshold (LT): At higher intensities, the body can still maintain the balance between lactate production and clearance, meaning you can “cruise” at a faster speed.

The value of understanding these mechanisms is this: when you know whether a particular workout is stimulating mitochondria or challenging lactate tolerance, you can more accurately judge “whether I should push hard today.” This is precisely the biggest gap between amateur riders and those who just ride casually.

2. Core Methods and Implementation Steps

2-1 Establish Your Baseline Data First

The first step in any scientific training is quantifying your current status. It is recommended that you obtain at least the following data:

1. FTP (Functional Threshold Power): Can be estimated via a 20-minute test (average power × 0.95) or a Ramp Test. This is the anchor point for all your power zones.
2. Maximum heart rate and resting heart rate: Maximum heart rate should ideally be measured during an actual hard climb, rather than using the rough 220-minus-age formula.
3. Weight and power-to-weight ratio (W/kg): For long climbs like those around the Hsuehshan Tunnel, W/kg is almost the decisive metric. A 65 kg rider with an FTP of 260W (4.0 W/kg) will be significantly faster on pure climbs than an 80 kg rider with an FTP of 280W (3.5 W/kg).

2-2 Power Zone Reference

Using FTP as the 100% baseline, the commonly used seven zones (Coggan model) are as follows:

2-3 A Sample Weekly Schedule You Can Execute

Using an advanced rider who can train 8–10 hours per week as an example:

• Monday: Rest or 30 minutes of Z1 active recovery on the trainer.
• Tuesday: Threshold intervals—after a 15-minute warm-up, do 3 × 10 minutes at Z4 (with 5 minutes of Z1 rest between sets).
• Wednesday: 90 minutes of pure Z2 aerobic riding, maintaining a cadence of 85–95 rpm.
• Thursday: VO2max intervals—5 × 4 minutes at Z5 (with 4 minutes of Z1 rest between intervals).
• Friday: Rest or an easy recovery ride.
• Saturday: Long ride, 3–4 hours, doing Tempo climbing around the Hsuehshan Tunnel.
• Sunday: 2 hours of Z2 social riding, plus some technical skill practice.

The spirit of this schedule is “Polarized Training”: approximately 80% of training volume falls in the easy Z1–Z2 range, and 20% falls at high intensity Z4 and above, deliberately avoiding the gray zone of Z3 where you’re “neither tired enough nor easy enough.” A large body of research shows that this distribution is the most efficient way to improve endurance performance.

3. Practical Application on Taiwan’s Local Routes

Now that the theory is covered, let’s put it back into real Taiwanese riding scenarios.

Around the Hsuehshan Tunnel—The Best Training Ground for Long-Climb Endurance

The area around the Hsuehshan Tunnel is a classic venue for testing your aerobic engine and pacing ability. The most common mistake people make on their first attempt is going out too hard: pushing power above Z4 before you’ve even settled in, causing your muscles to blow up early in the middle or later stages, forcing you to walk or stop for long periods. The correct approach is to set your target power near the “overall average power” you can sustain (usually slightly below FTP, depending on the climb length), and strictly control it with a power meter or heart rate monitor, saving the “heroics” for the final three kilometers.

Alishan Highway and Guanwu—Comprehensive Tests of Intensity and Technique

• On Alishan Highway, you can practice Tempo (Z3) climbing, building the muscular endurance to sustain sub-threshold output for extended periods.
• At Guanwu, the winding, undulating terrain is ideal for practicing cornering weight transfer and re-acceleration out of corners, which is crucial for events like the Taiwan KOM Challenge.

Local Considerations for Climate and Nutrition

Taiwan’s summers are hot and humid, with temperatures easily exceeding 35°C on flat roads. Heat dissipation is a severely underestimated limiting factor. High temperatures cause heart rate to be noticeably higher at the same power output (cardiovascular drift). If you stubbornly stick to heart-rate-based pacing in these conditions, you’ll end up undertraining. It is recommended that summer long rides be power-primary, heart-rate-secondary, with electrolyte-containing fluids every 15–20 minutes and 60–90 grams of carbohydrates per hour to avoid “bonking.”

In winter, at altitudes above 3,000 meters around the Hsuehshan Tunnel, temperatures can approach 0°C, making warmth and downhill wind chill another aspect that must be carefully planned.

4. Data Interpretation and Advanced Monitoring

Once you start accumulating training data (it’s recommended to use the Giant or Garmin ecosystem), you can manage training load with more objective metrics. The three most commonly used concepts:

Practical interpretation principles:

• CTL rising steadily: Keep weekly growth within 5–8 TSS/day. Rising too fast is a precursor to injury and overtraining.
• Positive TSB: Indicates fresh form, suitable for racing or testing; typically, you’d deliberately push TSB to +5 to +25 before a race.
• Chronically deep negative TSB: If it stays below −30 for several consecutive weeks, be highly alert to overreaching/overtraining.

Beyond load data, don’t overlook Heart Rate Variability (HRV) and morning resting heart rate. When HRV is consistently low, morning pulse is abnormally elevated, and sleep quality declines, these are signals from your body saying “I haven’t recovered yet”—and they deserve more attention than any scheduled rest day on your plan.

Common Data Pitfalls

1. Overestimating FTP: Setting zones based on a single test where you had exceptional form, causing every workout to be overloaded.
2. Only looking at average power, ignoring variability: The same 200W average, but with fluctuating “sawtooth power,” exacts a much higher physiological cost than steady output. This is the purpose of NP (Normalized Power).
3. Ignoring altitude and temperature context: 220W at 3,000 meters on Wuling carries a far greater physiological cost than 220W on flat ground, due to lower oxygen availability.

5. Common Mistakes and How to Fix Them

Based on long-term observation of Taiwanese cyclists’ training patterns, the following mistakes are the most common and most worth heeding:

1. Daily moderate intensity (Junk Miles): Every ride is “somewhat tired but not stimulating enough.” Over time, you neither build an aerobic base nor develop high-intensity capacity. Fix: Strictly distinguish between “easy days that are truly easy and hard days that are truly hard.”

2. Neglecting recovery: Treating rest days as laziness and feeling compelled to log rides every day. Fix: Recovery is part of training. Supercompensation happens during rest, not during training.

3. Equipment first, training second: Spending a fortune upgrading carbon wheels but refusing to invest time in structured workouts. Fix: For amateur riders, the engine (your body) has far more room for improvement than the equipment.

4. Only training what you’re good at: If you’re good at climbing, you only climb; if your sprint is weak, you never practice sprinting. Fix: Use pre-season fitness testing to identify weaknesses and target them specifically.

5. Overtraining before races: Still piling on volume the week before a race, then showing up carrying full fatigue. Fix: Do a “Taper” 7–14 days before the race—cut volume in half, retain a small amount of high-intensity stimulus, and let your body peak on race day.

Injury Prevention Reminders

Although cycling is a low-impact sport, Patellofemoral Pain Syndrome (PFPS), Iliotibial Band Syndrome (ITBS), and lower back pain are still very common, usually stemming from improper bike fitting or sudden spikes in training volume. Any new training plan should follow the “principle of progression,” and persistent pain should be addressed early rather than “riding through it.”

6. Putting It Into Your Long-Term Plan

No matter how beautiful a single workout looks, its benefits are diminished if it isn’t placed within a framework of Periodization. A typical annual macrocycle can be divided into:

• Base Period (8–12 weeks): Primarily large volumes of Z2 aerobic work to build the engine, paired with strength training and skill refinement.
• Build Period (6–8 weeks): Gradually introduce threshold and VO2max intervals to enhance specific capabilities.
• Peak Period (2–3 weeks): High intensity, low volume, with tapering arranged so your form peaks at the target event.
• Transition Period (2–4 weeks): Deliberately deload after the season ends, recharge mentally and physically, and avoid long-term accumulation leading to burnout.

Mapping this framework to Taiwan’s event calendar: if your goal is the autumn Taiwan KOM Challenge, then summer is your Build period and early autumn enters your Peak period. This timing allows your hard training to translate into results on the most critical day.

Recommendations for Riders of Different Levels

7. FAQ

Q1: I don’t have a power meter. Can I still use this approach?
Yes. Although power is the most precise training tool, you can still use “heart rate + Rate of Perceived Exertion (RPE)” as a substitute. Heart rate responds slowly and is easily affected by temperature and fatigue, so combining it with RPE (self-rated on a 1–10 scale) will be more reliable.

Q2: I can only train three times a week. What’s the most effective arrangement?
It’s recommended to use a combination of “one long aerobic ride + one threshold/VO2max interval session + one moderate Tempo ride,” concentrating your limited time on the highest return-on-investment stimuli, and ensuring sufficient recovery between sessions.

Q3: How long until I see progress?
Physiological adaptations typically take 6–8 weeks of consistent stimulus before they clearly show up in your data. Patience is the most underrated ability in endurance sports—avoid testing your FTP every week and doubting yourself.

Q4: Can indoor trainers and outdoor riding replace each other?
Indoor trainers (such as the Merida smart rollers) have an advantage in “precisely controlling intensity,” making them particularly suitable for intervals; outdoor riding is irreplaceable for practicing bike handling, pacing, and mental toughness. The ideal approach is to use both as complements, not as an either/or choice.

Conclusion

Returning to the core of this article: “Training adjustments for older riders” is not some magical workout plan or expensive equipment, but rather a long-term mindset of “understanding principles → quantifying current status → structured execution → data feedback → continuous adjustment.” The next time you ride the long climbs around the Hsuehshan Tunnel, I hope you won’t just grit your teeth and push through by feel, but will clearly know which energy system you’re training at that moment, why you’re pacing that way, and how this ride fits into the blueprint of your entire season.

Training is a long-term dialogue with yourself. May you ride smarter, healthier, and faster on every road in Taiwan. Before you head out next time, ask yourself one question: “What’s the purpose of this ride today?” If you can answer it clearly, you’ve already beaten most riders.

This article is a training knowledge share. Individual training plans should still be adjusted according to personal fitness, health conditions, and professional coach recommendations. If you have cardiovascular disease or old injuries, please consult a physician before starting any high-intensity training.
