Just like the charity campaign it supports, the Santa Hash fun run has been expanding for a quarter of a century, proving that charity, fun and sport are a good mix.
This year's effort, organised by a group of hill-running, beer-drinking enthusiasts, saw a turnout of more than 150 participants on Sunday, the highest in recent years. It is in its 25th year, coinciding with the same anniversary of Operation Santa Claus (OSC).
"Everyone comes out because it's for charity. It's about running for fun and a bit of drinking," said Mark Hope, who was the "hare" this year - the runner responsible for laying the track with chalk and flour.
OSC raised a record HK$17.5 million last year and is aiming for more this year, which it will pass on to 18 beneficiaries.
Hong Kong's 13 Hash House Harrier clubs each organise weekly runs, and all join together for the Santa Hash. Hashing is similar to the old sport of hare and hounds, where the "hare" lays a trail and for the pack of "hashers" to follw.
Sunday's trail was six kilometres long - seven for those who took a more challenging route - from Aldrich Bay park in Shau Kei Wan, up the hills of Sai Wan Ho and Quarry Bay, and back.
