Lillebæltsstien (in english: Lillebaelt Trail) is a footpath mainly on dirt/gravel trails, single trails and a few sections on concrete/pavement. I connects the small towns of Strib in the north and Gamborg in the south. The trail is well marked with blue signs all the way, and with a few exceptions it follows the paths closest possible to the sea. The trail passes through iconic coastal landscapes, beaches, steep slopes, cozy towns, open fields and forests. 

Trail en Famenne (https://www.trailenfamenne.be/en) is a second setup (like ExtraTrail) of training trails from 6 different places in the south of the Ardennes in Belgium. In each place there are four routes (green, blue, red and black) where the black routes are the longest (32-42 km) and all have above 700 m of elevation. Unlike the ExtraTrail system the villages are not interconnected. The Somme-Leuze black circuit take you to the villages of Moressée, Ramezée, Somal and Failon in the Condroz region and to Nettinne. Offroad: 70 %.
