Luxembourg runners: get on your night gear and tie up those laces to join some 25,000 athletes to run in the dark.
Luxembourg is among some 50 cities participating in the event worldwide. As the event is aimed to be an informal run, runners will not be chip-timed.
Runners can select between 5k or a 10k (two loops on the course). Entries close on 11 November, so book early to guarantee your spot via the Run in the Dark website.
