The Bike at Penghu: 178 km Where the Wind Rules

The Course: Three Loops Across Three Islands

The official page lists 178.1 km over three loops, with two turnarounds and 1,205 m of elevation gain. There are no real climbs: it's constant rollers, with the Penghu Great Bridge and the long causeway bridges connecting the archipelago's three islands. A 2026 finisher reports crossing the big bridge six times during the race, head down the whole way because of the wind. Special needs is at the Xiyu West Fort parking lot, at the turnaround: put extra nutrition and a spare tube in there. You pass aid stations 10 times in total: use them as checkpoints to drink and eat, don't ride straight through.

The Wind Decides the Race

Penghu is a windsurfing capital, and not by accident. Wind is the number one factor on this leg, more than the elevation and more than the heat. Past editions tell the story: in 2025 a cold front brought massive gusts the night before the race. The bike course was modified that very morning to avoid the most exposed sections and ended up longer, around 185 km. Several race reports from that edition describe violent crosswinds for most of the 185 km and crashes during the race. In 2026, by contrast, a finisher reports wind that was less brutal than feared but still draining for the entire leg. Bottom line: you don't know which Penghu you'll get. Prepare for the worst version.

The critical sections are the causeway bridges between the islands: long, flat, completely exposed, with no shelter. With crosswinds and deep-section wheels they become a balancing act. Here you need bike handling, not watts.

Pacing: Power, Not Kilometers

The most important takeaway in this guide: the course can change on race morning. It has happened before. So don't build a plan tied to exact kilometers ("at km 90 I do X"). Build a plan based on power or feel, split into blocks: loop 1 conservative, loop 2 at race effort, loop 3 managed with the marathon in mind. Into a headwind, resist the temptation to push to "make up" speed: it burns your race. With a tailwind, press on, that's where you gain for free.

If you use a power meter, set a ceiling for the headwind sections and stick to it. If you ride by feel, use the 10 aid station passes as reset points: check what you've drunk and eaten in the last block.

Equipment and Gearing

In a past edition, disc wheels were banned due to strong wind forecasts (conditions turned out fine, but the ban stood). Even without a ban, in Penghu's wind a mid-depth front wheel is safer than a deep one. Consider bringing two options and decide after the briefing and the weather forecast. Gearing: with 1,205 m of climbing spread over rollers you don't need mountain gearing, but into a strong headwind you'll be pedaling at climbing speeds: a slightly easier cassette is not a mistake.

What to Do Between Now and Race Day

• Train in the aero position in crosswinds and gusts, on open, exposed roads. If the bars scare you in a 40 km/h wind in training, they'll scare you more in the race.
• Prepare two power plans: one for 178 km, one for a lengthened or modified version.
• Test the wheels you'll race on in windy conditions, not just on good days.
• Decide now what goes into the Xiyu West Fort special needs bag: extra nutrition and flat repair kit.

You don't win the Penghu bike: you manage it. Whoever gets to T2 with legs and head intact has already done half the job.
