The largest tributary of the Sence is the Saint, with a headwater called the Tweed rising near Barwell (GR SP435961; alt. 125 m) and on Barwell Lane (GR 438957; alt. 115 m). A branch from Hinckley (GR SP429951; alt. ca 125 m) joins the Tweed south-west of Stapleton, south of Harper's Hill. The Tweed runs west almost to Dadlington, whence it is canalized north-west to the confluence with Stapleton Brook. It then runs west along the foot of Ambion Hill. It gains a stream from between Higham on the Hill and Wykin running north and another from Lindley running north-east and turns north to Shenton, where it joins a smaller stream running west from Cadeby (GR SK429020; alt. 128 m) to become the Saint flowing westwards. A large stream from the north rises west of Market Bosworth and north-west of Hoo Hills, Wellsborough, passing the Bosworth hamlet of Far Coton to join the Saint on Upton Ridge. Thence the Saint continues west to Sibson and meanders to the Sence between Sheepy and Ratcliffe Culey (GR SK326999). In general, its course from Barwell to Ratcliffe covers about 13 km, in which it falls about 50 m, a gradient of about 1:650, resulting in a slower flow than of the Sence, and a muddy, marshy and more meandering channel than the Sence. Only across the Upton-Linley north-south ridge between Shenton and Sibson is its flow faster.
