Its source is located near the Odeon cinema at the eastern edge of Thornbury. The stream crosses the grounds of Phoenix Park Golf Course between Farsley and Thornbury. A longer source arm which originates near runs along the southern edge of the golf course, immediately north of the railway between Bradford and Leeds. The two arms join immediately west of Daleside Road near . The stream runs initially in a roughly eastern direction. Daleside Road crosses over it as well as the railway line. Then Tyersal Beck turns nearly south, skirting the edge of Upper Moor, and runs along the valley between Tyersal and the western edge of Pudsey town, where it passes through the embankment of the former Pudsey Loop railway line in a culvert. This embankment, built in the late 19th century, was claimed to have been the largest man made embankment in Europe at that time. After joining with Carr Beck, it describes a wide arc and, while meandering at the bottom of a wide valley, turns east towards the southern edge of Fulneck Golf Course where it is joined by Holme Beck. The joint stream continues as Pudsey Beck.
