01 Race Card
Your first range uses conservative assumptions. Add optional evidence to make it more specific. It is calculated in your browser and saved only on this device.
02 The course
You swim two triangular laps at Shili Beach, ride a point-to-point 180 km route across the Penghu archipelago via routes 201, 204, 11, 12 and 203, crossing the Penghu Great Bridge three times between two turnarounds, then run a flat 42.2 km course past famous landmarks including the Xiying Rainbow Bridge and the world's tallest bronze Matsu statue to the finish at Penghu's Third Fishing Port. The organiser itself compares Penghu's climate and wind to Hawaii's, calling it ideal preparation for Kona. Strong island wind, not gradient, is this course's real defining challenge, especially across three bridge crossings.
Swim
3.8 km
A two-lap triangular ocean swim at Shili Beach gives a straightforward opening before the wind becomes the day's real subject.

180 km
A point-to-point route across the Penghu archipelago, including three crossings of the exposed Penghu Great Bridge, makes strong island wind the defining test the organiser itself compares to Kona.
Source: 2027 current routeRun
42.2 km
A flat run past the islands' famous landmarks offers a break from the wind's demands, rewarding whatever the bike's crosswinds left in the legs.

03 Race plan
One job for each part of this course. The distance markers tell you when the job changes. The course tells you why.
Swim
Two counter-clockwise triangular laps, with a beach exit and re-entry between them, are straightforward to navigate. Use the calm start to settle before the bike's real test begins.
Bike
Riding out via routes 201, 204, 11 and 12 past Guoye Elementary and Husi Junior High, set the power number you intend to hold once the wind picks up on the bridge crossings ahead.
Route 203 crosses the Penghu Great Bridge three times between two turnarounds, the course's most wind-exposed section. Ride to a power number, not a speed target, and expect that number to buy less speed than usual here.
Passing Tianjun Temple toward T2, hold your discipline through the closing kilometres rather than chasing back time the wind took from you earlier.
Run
The run passes Guanyinting Recreation Area and the Xiying Rainbow Bridge on largely flat terrain, a welcome change after the bike's wind. Open conservatively regardless of the relief.
Passing the world's tallest bronze Matsu statue and through the downtown hotel area, use these fixed points to check pace against your plan.
Completing the A-B and C-H lap-band segments a second time, this is where the cumulative cost of the bike's crosswinds starts to show. Manage the effort you actually have.
The finish at Penghu's Third Fishing Port International Plaza rewards a bike that respected the wind and a run paced across all four lap-band segments.
04 Race week
There is no useful 2027 forecast this far out. For now, past race dates give us a point of reference. Closer to the race, the forecast will tell us whether the plan needs changing.
A race-day forecast is not meaningful yet; check back closer to the event.

05 Method
Your CSS, FTP, weight and run threshold create the first range. Open-water, bike, run and execution evidence can replace broad assumptions. Course data and the historical conditions baseline shape every simulation.
Confidence is built from four inputs
It starts with the targets in your Race Card, then samples the parts of a full distance that vary: open-water pace, transitions, bike speed at the planned power, and the drop in run performance after the swim and bike. Repeating that calculation produces a likely range rather than a single heroic number.
The current time calculation uses this race’s published distances, or standard full distance distances where none are published, with the available course headings, elevation and exposure evidence. Weather scenarios vary temperature, dew point, wind, gusts, rain and water conditions together. Unknown route detail stays visible as uncertainty rather than false precision.
It is not predicting your exact finishing time, placing, or race-day weather. It answers a narrower question: given the plan and the information we have, what range of day is plausible, and where is the uncertainty coming from?
Confidence is not a permanent “low”. It is recalculated across four separate inputs:
It starts low when those inputs are broad. It can become moderate or high as the evidence improves. A narrower range means better information, not a guarantee.
