The HK100 course is based around Hong Kong's famous MacLehose Trail, taking runners across scenic country parks, beaches, ridges, and finishing with the descent from Tai Mo Shan.
What this race demands
HK100 demands sustained endurance across 100 kilometers and 5,142 meters of elevation gain on varied trail terrain.
Climbing volume
Over 5,000 meters of elevation gain across 100 kilometers requires significant climbing strength and muscular endurance for continuous ascending.
Technical descending
The course profile and terrain featuring ridges, beaches, and the final descent from Tai Mo Shan demand robust eccentric leg strength and stability.
Extended durability
Covering a 100-kilometer trail distance tests long-duration aerobic capacity and pacing discipline well beyond standard marathon durations.
Given the extended duration, athletes should target 60 to 90 grams of carbohydrates per hour to maintain energy output throughout the event.
Estimated finish times
Estimates by level, not promises. Your own number depends on your fitness on the day.
