Červený okruh is a cross/trail race held at the Na střelnici, also known as Termit, area in Doksy, Liberec Region. It is part of the Česká Lípa District Running League and is organized by Atletický oddíl TJ Doksy, with Jaroslav Novák as race director. The main adult distances are 9.2 km and 3.8 km, and the program also includes children’s races starting from 100 meters.
The main course is a fast forest loop on pine-needle paths, featuring 62 meters of total elevation gain. The first 4 km ascend gradually, followed by a descent in the second half, making it suitable for runners who prefer quick off-road courses without significant climbs. The shorter route shares the initial 1.7 km before a sharp left turn leads back towards the Termit area. Both courses are marked year-round, allowing locals to train on the precise route before the event.
