The TBA Four Lighthouse 620 is a 620 km chip-timed cycling certification challenge from Fulong Visitor Center in Gongliao, New Taipei City, to Eluanbi, passing four lighthouse checkpoints along Taiwan's east and west coasts, starting at 20:00 on 13 November 2026 with a 35-hour time limit.
What this race demands
This 620-kilometer cycling certification challenge requires sustained riding through a 35-hour time limit starting at night. Athletes must manage extreme ultra-distance fatigue and nighttime pacing across Taiwan's coastlines.
Ultra-distance endurance
Covering 620 kilometers demands exceptional aerobic endurance and the physical capacity to sustain forward motion well beyond standard double-century distances.
Night riding management
With a 20:00 start time, riders face an immediate nocturnal leg requiring effective lighting management, alertness maintenance, and circadian rhythm adaptation.
Time limit pressure
The strict 35-hour cutoff requires disciplined time management at checkpoints, efficient transitions, and careful control of time spent stopped to ensure completion.
A continuous carbohydrate intake of 60 to 90 grams per hour is necessary to support energy availability across the multi-day duration.
