It rises on Warren Moor, part of Kildale Moor, in the North York Moors and flows to the north of the moors to join the River Tees at Yarm. The source of the river is on Warren Moor, part of Kildale Moor, just south of the village of Kildale. It flows east until it reaches the Whitby to Middlesbrough rail line where it does a complete turnaround to flow west to Kildale. It then flows south-south-west through woodland to the

Notable athletes to train at both facilities are World & European Indoor Sprint Champion Richard Kilty, British Indoor Long Jump record holder Chris Tomlinson and current British Internationals Matthew Hynes, Jonathon Taylor, Rabah Yousif and Amy Carr.
