Team Fillinge Ultras Terränglopp is a local trail race of approximately 10 km, held on the first Advent near Fillinge, south of Bankekind and Linköping in Östergötland, Sweden. Team Fillinge Ultra organizes the event, with participants meeting at Gummiverkstaden for a brief information session before the late-morning start.
The course consists mainly of gravel roads and trails, suitable for runners seeking a relaxed off-road run in nature, distinct from a large-city race. This is the event's second edition, maintaining a relaxed and friendly atmosphere with a straightforward format centered on a single short trail course and a finish around lunchtime.
