I have just updated the course route to the correct route for this year ending in Cheung Sha not Pui O. I used the Moonlit 30 from 2013.
50km starts at 20:10
40km starts at 20:30
30km starts at 23:00
Now, you gotta know your course and race times directly from Moontrekker as they may update or change things i don't do here...so if they say something different, they are right.
