Course Map & Elevation
This route is generated and may not follow the exact official course.
Course Overview
A flat riverside loop course with only 20m of total elevation gain, tracing the Keelung River corridor through Taipei with a secondary loop through Dazhi and Meiti Park. The course sits between 5m and 20m above sea level. Despite December timing, the defining challenge is Taipei's persistent subtropical humidity — rarely below 70% — which limits cooling and demands deliberate hydration strategy.
Key Segments
City Hall to Dazhi District
Terrain: Flat to gently rising from 10m to 10m along the Keelung River bike path, entering the Dazhi District with slight elevation gain
Challenge: The flat riverside path and cool start temperatures tempt aggressive early pacing. Taipei's humidity masks true effort level.
Tactic: Settle into goal pace from km 1. Resist banking time — the course feels easy early but the humidity compounds fatigue relentlessly over 42km.
Meiti Park Loop
Terrain: Gradual climb to the course high point (~20m) at Meiti Riverside Park around km 13-15, then descending back to river level by km 21
Challenge: The only meaningful elevation on the course arrives when legs are still fresh — easy to overcook this section
Tactic: Stay disciplined through the gentle climb. This is the place to check heart rate — if above Zone 3 on the climb, back off. Crest the high point and settle into flat rhythm.
Outbound River Corridor
Terrain: Dead flat along the Keelung River bike path at 7-11m elevation, wide and exposed
Challenge: Flattest and most exposed section. Northeast monsoon winds create headwind or crosswind. Aid stations spaced every 2.5km demand careful hydration planning.
Tactic: Run even effort, not even pace, on windy sections. Take fluid at every station even if not thirsty — humidity means sweat loss remains significant despite cooler temperatures.
Return to City Hall
Terrain: Flat return along sheltered riverside sections between embankments and tree lines, finishing on urban roads near Taipei City Hall
Challenge: Classic late-race fatigue on a flat loop — no hills to break stride pattern, no scenery changes to distract the mind
Tactic: Mental preparation is as important as fitness here. Focus on cadence and form. Begin final push at km 40 as you re-enter the Xinyi District urban roads.
Race-Specific Training
- •Practice running the final 10km of long runs at race pace to build specific late-race resilience on flat terrain — the monotony is the challenge
- •Train in humidity wherever possible: treadmill sessions with elevated temperature, or wearing an extra layer on easy days, to adapt to moisture load
- •Practice drinking while moving on every long run — Taipei's humidity means sweat loss of 600-900ml per hour even in cool temperatures
Conditions & Environment
Altitude
Entire course at 5-20m above sea level. No altitude concerns.
Weather
December race. Start temps typically 12-18°C (54-64°F). Humidity rarely drops below 70%. Rain possible — December sits between typhoon season and the cold northeast monsoon.
Sun & Wind
Morning sun clears surrounding hills around 7-8am, warming quickly. Northeast monsoon winds create crosswind or headwind on westbound river stretches.
What to Wear
Single breathable layer. Pack a disposable rain poncho for the start. Moisture-wicking socks and anti-chafe balm are essential in humid conditions.
Pacing Strategy
| Segment | Pace | Note |
|---|---|---|
| km 0-10 | Goal pace | Settle in early. The flat river path feels easy — resist banking time. Check heart rate against humidity-adjusted targets. |
| km 10-21 | Goal pace, controlled on the climb | The Meiti Park loop is the only elevation. Stay disciplined through the gentle rise and descent. |
| km 21-33 | Even effort (adjust for wind) | Flat and exposed river corridor. Wind direction varies — run by effort, not GPS pace. |
| km 33-42.195 | Goal pace or faster if strong | Sheltered return sections. Mental toughness carries you here. Begin final push at km 40. |
Race Day Tip
If traveling from Western time zones, arrive at least three full days before race day for jet lag adjustment. The MRT Taipei City Hall Station (Blue Line) puts you directly at the start/finish — avoid driving. Collect your bib at the expo early to avoid Saturday crowds and save your legs.
