A coastal 50km loop spanning the full beauty of the Sai Kung Peninsula
The Half is a challenging 50km loop from Pak Tam Chung exploring the full length of the Sai Kung coast — tracing the Maclehose Trail past High Island Reservoir, crossing three remote beaches at Long Ke, Ham Tin, and Tai Long Wan, climbing the impressive Ngau Yee Shek Shan with panoramic island views, and winding through coastal villages before descending to the finish. With over 2,100m of climbing in 50km, the Half punches well above its weight class.

This edition has its own course and we haven't mapped it yet. The interactive map, elevation profile and aid stations will appear here once the route is confirmed.
We do have the 2026 route on file. We aren't showing it here, because a race's course — and sometimes its finish line — can move between editions, and a stale map is worse than no map.
Aid stations for this edition aren't published yet. They'll appear here once the route is confirmed.
