The 1418 Noctrail takes place in mid-December in Noyon, located in the Oise region of northern France. Participants can select from 10 km, 16 km, or 24 km trail runs. Additionally, an 8 km night walk is available for those seeking the event's atmosphere without the competitive aspect. The event requires participants to use headlamps, with the core concept being to run or walk after sunset on marked trails, without any artificial obstacles.
The routes for each distance consist of a single loop. The elevation gain varies from 210 m for the 10 km course, to 310 m for the 16 km, and 530 m for the 24 km. The 24 km trail is the most frequently chosen option. Participant numbers are limited to 1,000, preventing the feel of a large-scale city event. The atmosphere is intentionally lighthearted and athletic, incorporating a subtle Christmas theme appropriate for its December timing.
