Runners all over the world are dressing up in their best Santa Claus costumes!
And it is for a good cause. This race helps raise money to support underprivileged kids along with vulnerable elderly who are located in Hong Kong and other communities in China.
Runners had the choice to either run a 3km, 8km, or a 1k Christmas fun walk.
This makes running look like so much fun!
