Taiwan’s mountainous terrain, extensive coastline, and dramatic topography have fostered a world-class riding environment. The Yilan Beiyi Highway Riding Guide deserves a dedicated in-depth article precisely because it condenses the essence of cycling in Taiwan into a single route. This article will start with the overall outline of the route, break down the terrain and gradients section by section, and then extend into pacing strategies, refueling rhythms, safety risks, and pre-race training cycles, aiming to give both first-time visitors and seasoned riders looking to set a new personal record (PR) a complete and three-dimensional understanding of the route before setting off.

1. Route Overview and Geographic Background

This route is located in Taipei・New Taipei・Yilan, connecting landmarks such as Shiding Thousand Island Lake, Pinglin Tea Country, and the highest point of the Beiyi Highway, making it a classic cherished among local riders. From a geographic perspective, Taiwan’s mountain ranges, monsoon patterns, and land-sea boundaries profoundly influence the riding experience of every route. The Beiyi Highway (Provincial Highway 9) is a classic challenge crossing the Snow Mountain Range from Greater Taipei to Yilan, combining climbing with technical long descents.

Understanding the “personality” of a route is the first step in planning a ride. We can imagine the entire route as a piece of music: a warm-up prelude, a main theme that gradually builds tension, a climax that truly tests your willpower, and finally a closing section that returns to calm. Only by grasping the overall structure first can you invest the right effort in the right sections, rather than burning all your matches at the start.

• Route Characteristics: Continuous climbing from Shiding to Pinglin, followed by a long descent after the pass
• Recommended Season: Spring and autumn are best, avoiding the rainy season and heavy fog
• Overall Difficulty Rating: Varies by individual fitness; it is recommended to assess your own continuous climbing endurance and long-distance experience before deciding on the challenge category and target time.

2. Section-by-Section Terrain and Gradient Breakdown

The most effective way to ride a route well is to break it into several “mentally manageable” segments, setting pacing and refueling goals for each. Below, the route is divided into three main parts based on terrain characteristics: the warm-up segment, the main climbing (or main cruising) segment, and the decisive segment.

2-1 Warm-Up Segment: Establish Rhythm, Avoid Overheating

The early section after departure is key to establishing rhythm. A common mistake many riders make is going out too hard under the influence of adrenaline, leading to an early “bonk” in the middle or later stages. The correct approach is to keep your heart rate in the aerobic zone (approximately 70% to 80% of maximum heart rate), starting at an intensity slightly below what feels comfortable, allowing the body to gradually ease into working mode.

Cadence in this section should be maintained at 85 to 95 rpm, using a lighter gear ratio and higher cadence to warm up the legs, avoiding the accumulation of excess lactate from grinding a big gear from the start. At the same time, use this period to check your equipment: tire pressure, shifting, brakes, and the location of your supplies, ensuring everything is ready.

2-2 Main Segment: The Core Tension of the Route

Once you enter the core of the route, the terrain characteristics (continuous climbing from Shiding to Pinglin, followed by a long descent after the pass) will truly test your abilities. If this is a climbing route, focus on “sustainable maximum steady output,” meaning riding at an intensity close to but not exceeding your lactate threshold; if this is a flat or coastal route, the emphasis is on maintaining efficient cruising and paceline rhythm while properly handling crosswinds.

Pacing Principles	Climbing Route	Flat／Coastal Route
Intensity Basis	Power approx. 75–88% of FTP, lower edge of heart rate threshold	Power approx. 70–80% of FTP, upper edge of aerobic heart rate
Cadence	70–85 rpm, adjusted by gradient	90–100 rpm, maintaining smoothness
Gear Strategy	Reserve light gears for the steepest sections, shift early	Use medium-to-large gears for cruising on flats, downshift into headwinds to preserve cadence
Refueling Timing	Refuel energy and fluids every 30–45 minutes	Refuel every 40–60 minutes, paying attention to electrolytes

The most important principle in this segment is “holding back.” The art of pacing lies in this: when you feel like “I could actually go a little faster right now,” that is often exactly the right intensity. Suppress the extra urge and save it for the true decisive segment.

2-3 Decisive Segment: The Sum of Willpower and Technique

The final segment of the route is often where success or failure is determined. If the finish is at the top of a climb, this is usually the steepest, highest, and coldest section, where fatigue has accumulated and the air is thinner—only the energy saved in the earlier sections and unwavering determination can carry you to the finish. If it is a long flat section, the final part requires fighting against accumulated fatigue and declining focus.

When descending or on the return leg, always prioritize “safety” over “speed.” When cornering, use an outside-inside-outside line, complete your braking before entering the turn, avoid heavy braking mid-corner, keep your center of gravity low, and look toward the exit of the turn. Mountain roads in Taiwan often have fallen leaves, moss, gravel, and slippery surfaces—better to go a little slower than to risk your safety.

3. Highlights Along the Way and Must-See Scenery

The most captivating aspect of this route is the rich cultural and natural scenery along the way. Below are the key landmarks, with a recommendation to slow down and savor them when it is safe to do so—after all, cycling is not just about the numbers, but also about encountering this land.

No.	Highlight Landmark	Riding Suggestion
1	Shiding Thousand Island Lake	Landmark along the route; recommended to slow down, be mindful of photo stops and traffic flow
2	Pinglin Tea Country	Landmark along the route; recommended to slow down, be mindful of photo stops and traffic flow
3	Beiyi Highway Highest Point	Landmark along the route; recommended to slow down, be mindful of photo stops and traffic flow
4	Paoma Historic Trail	Landmark along the route; recommended to slow down, be mindful of photo stops and traffic flow
5	Lanyang Plain Viewpoint	Landmark along the route; recommended to slow down, be mindful of photo stops and traffic flow

Behind every landmark lies a story of Taiwan—whether it is a history of pioneering, a center of faith, or mountains and coastlines guarded by generations. As you pass these places between pedal strokes, take an extra look—that is the most precious nourishment of cycling in Taiwan.

4. Refueling Strategy and Stop Arrangements

In long-distance and climbing rides, refueling often accounts for half the battle. During high-intensity exercise, glycogen is continuously depleted, and once it bottoms out, you experience what is commonly called “bonking.” Smart riders adopt the principle of “small amounts, frequent intake, refuel early,” rather than waiting until they are hungry or thirsty to replenish.

4-1 Main Refueling Stops

• Shiding Convenience Store: An ideal stop for water, supplies, and a short rest.
• Pinglin Town Center: An ideal stop for water, supplies, and a short rest.
• Jiaoxi Hot Spring Area: An ideal stop for water, supplies, and a short rest.

4-2 Refueling Rhythm Recommendations

• Fluids: Replenish approximately 500–750 ml per hour, increasing in high heat or high intensity. Monitor sweat rate and thirst levels to avoid both dehydration and overhydration that dilutes electrolytes.
• Carbohydrates: High-intensity riding requires approximately 60–90 grams of carbs per hour, which can be supplied by energy gels, energy bars, bananas, or local snacks. For longer rides, consider electrolyte tablets to supplement sodium and prevent cramping.
• Local Cuisine: One of the great joys of Taiwan’s routes is turning refueling stops into culinary adventures. Local snacks along the way not only replenish calories but also become memorable highlights of the journey; however, during races, stick to foods that are easy to digest and gentle on the stomach.

5. Safety Risks and Equipment Checks

No matter how beautiful the route is, safety always comes first. For this route, here are the risks that require special attention:

• Mixed traffic with heavy motorcycles: Always anticipate ahead, reduce speed, and leave room for reaction.
• Speed on downhill corners: Always anticipate ahead, reduce speed, and leave room for reaction.
• Wet roads and dense fog during the rainy season: Always anticipate ahead, reduce speed, and leave room for reaction.

Equipment Checklist:

1. Helmet: Mandatory for every ride; confirm the strap is secure and the fit is snug.
2. Lights and Reflectors: Turn on front and rear lights in tunnels, early morning, evening, or fog; wear high-visibility clothing.
3. Tire Condition and Spare Tubes: Check tire pressure and tread before departure; carry inner tubes, tire levers, and a pump/CO2 inflator.
4. Warmth and Sun Protection: Temperature swings are large at high altitude or on descents; pack a windbreaker and arm warmers. On flats and coastal sections, pay attention to sun protection and hydration.
5. Communication and ID: Fully charge your phone, carry ID and some cash, and let family know your route and estimated return time.

6. Suggested Pre-Race Training Periodization

To complete this route safely and with a sense of accomplishment, a 8- to 12-week periodized training plan is recommended. Below is a general framework that riders can adjust based on their own base:

Phase	Focus	Example Content
Weeks 1–3 (Base Phase)	Build aerobic foundation	2–3 long aerobic rides per week, heart rate in Zone 2, gradually extending duration
Weeks 4–6 (Build Phase)	Improve threshold and climbing power	Add threshold intervals (e.g., 4×8 minutes), repeat hill climbs
Weeks 7–9 (Specific Phase)	Simulate route demands	Schedule long rides close to target distance and elevation gain; practice fueling and pacing
Weeks 10–12 (Taper Phase)	Fine-tune condition	Reduce training volume, maintain intensity; rest fully and top up glycogen in the final week

Beyond training, don’t neglect stretching, strength work, and rest. Core and lower-body strength improve pedaling efficiency and stability, while adequate sleep is the foundation of recovery and progress. Treat training, nutrition, and recovery as the three legs of a tripod—none can be missing.

7. Weather, Seasons, and Timing

Taiwan sits at the boundary of the subtropics and tropics, with the towering Central Mountain Range intercepting moisture, so weather affects riding far more dramatically than one might imagine. For this Taipei・New Taipei・Yilan route, spring and autumn are the best seasons; avoiding the rainy season and fog is the optimal timing verified by local riders. But even in good seasons, many details deserve attention.

• Afternoon thunderstorms: Especially in summer, convective thunderstorms are common in Taiwan’s mountain areas in the afternoon. Not only are the roads slippery and dangerous, but lightning is a lethal threat. It’s best to “start early and return early,” completing the main climbs or itinerary before noon to avoid unstable afternoon weather.
• Fog and visibility: High-altitude and river-valley sections are prone to afternoon fog, and a sudden drop in visibility greatly increases the risk of encounters with vehicles. In fog, turn on front and rear lights, wear bright clothing, and reduce speed.
• Temperature swings and hypothermia: Taiwan’s elevation differences can create all four seasons within a single route. Sweat-soaked clothing from climbing can rapidly strip body heat on long high-altitude descents, causing hypothermia and muscle stiffness. Carrying a windbreaker, arm warmers, and even thin gloves is essential for long climbing routes.
• Monsoon winds and crosswinds: During the winter northeast monsoon, coastal and outlying sections face crosswinds and headwinds that significantly increase difficulty and danger. In strong winds, reduce speed, hold the drops to lower wind resistance, and keep a safe lateral distance from companions.

Choosing when to depart isn’t just about avoiding bad weather—it’s also about avoiding peak traffic. Tourist hotspots are often crowded on weekends, while early mornings on weekdays are comparatively quiet, allowing you to focus more on the ride itself.

8. Bike Setup and Gear Ratio Recommendations

“Sharpen your tools before you start your work.” Given the terrain characteristics of this route (continuous climbing from Shiding to Pinglin, followed by a long descent after the pass), whether your bike setup is sensible directly determines how easily you can finish.

Item	Recommended Setup	Notes
Gear Ratio	For climbing routes, compact crankset 50/34 up front, 11–32T or larger cassette in the rear	Leave margin for your knees and lungs; avoid grinding hard and injuring your knees
Wheelset	Low-profile lightweight for climbing; mid-to-high profile for flats and coastal sections	Balance light climbing feel with efficient flat cruising
Tire Pressure	Adjust based on body weight and tire width; lower slightly in mountains and on wet roads	Improves grip and comfort, reduces puncture risk
Brakes	Check brake pads and hydraulic/mechanical systems before departure	Long descents are a severe test for brakes; ensure stopping power is guaranteed

Pedaling and Position: Over long distances, correct frame size and fit prevent cumulative injuries to the knees, lower back, and wrists. If you plan to take on similar routes long-term, investing in a professional bike fitting is worthwhile. Standing to climb (out-of-saddle efforts) engages different muscle groups and relieves saddle pressure, but it consumes more energy, so use it strategically when the grade steepens or when you need a short burst of speed.

9. Pacing Math: Managing Your Effort with Numbers

Many riders ride by feel, ending up either too conservative with regrets or too aggressive and blowing up midway. In fact, mastering a few simple numerical concepts allows you to allocate your energy more scientifically.

• Negative split principle: In an ideal long ride, the average intensity of the second half should be equal to or slightly higher than the first half. In other words, “hold back” in the early stages, keeping your perceived exertion at a level where you can still hold a conversation.
• Estimating climb time: Climbing 100 meters of vertical gain takes roughly 8 to 15 minutes for an average rider, depending on gradient and fitness. With this route’s approximately 800 meters of climbing, the vertical gain alone could take several hours—be sure to factor this into your fueling and weather planning.
• Power-to-weight ratio (W/kg): Climbing performance depends heavily on power-to-weight ratio. If you can sustain a steady output of 2.5 to 3 watts per kilogram, most classic Taiwanese climbs can be completed in a reasonable time; to chase a faster time, you’ll need to push that number higher.
• Heart rate anchoring: Riders without a power meter can use heart rate as a pacing guide. Keeping your main effort’s heart rate at the lower edge of your threshold (around 85% of max heart rate) is the sweet spot balancing speed and endurance.

Apply these principles to the Taipei・New Taipei・Yilan terrain, and you’ll find that “slow is fast”—every bit of energy saved in the early stages pays back double in the decisive sections.

10. Common Beginner Mistakes and FAQ

Q1: What’s the most common mistake when tackling this route for the first time?
A: Starting too fast. Adrenaline causes people to unconsciously accelerate in the early stages, leading to a collapse in the middle and later sections. Deliberately keep the early intensity low.

Q2: How much fuel should I prepare?
A: Better to over-prepare than under-prepare. Estimate the calories needed based on route distance and climbing, then add 20% as a buffer. Energy gels, energy bars, and electrolyte tablets are standard for long rides.

Q3: What should I do if it rains or fog rolls in?
A: Safety first. If the weather clearly deteriorates, don’t push it. Reduce speed, turn on lights, keep distance, and take shelter or turn back if necessary. The mountain isn’t going anywhere—getting home safely is what matters most.

Q4: Is it better to ride solo or with a group?
A: For routes with scarce resupply and complex road conditions (such as the risk points mentioned for this route), riding with companions allows mutual support and rotating pace-setting, making it safer and more enjoyable. Whether solo or in a group, always inform someone of your itinerary and estimated return time.

Q5: How do I know if I’m ready?
A: If you can complete a long ride in training covering roughly 70–80% of the target distance with similar climbing without being completely exhausted, you generally have the foundation to take on the challenge. The rest is up to pacing and willpower.

11. Key Principles and Final Thoughts

The Beiyi Highway Cycling Guide is more than just a route—it is a mirror reflecting yourself. It will honestly tell you whether your preparation is sufficient, your pacing is appropriate, and your willpower is firm. When you stand at the finish line and look back at the road you’ve traveled, that sense of accomplishment cannot be fully measured by any data.

Finally, three words of advice for all cyclists who want to take on this route: Respect the route, respect your body, and respect this land. Do your homework, manage your pace, and take in the scenery. You’ll find that every route in Taiwan is a journey of dialogue with yourself. May you ride safely, ride joyfully, and write your own story.
