Thirsk White Horse Swim Team (TWHST) was formed in January 1999 following a merger between Hambleton Swim Squad and Thirsk Amateur Swimming Club.

TWHST is a friendly club catering for swimmers of all ages and abilities. We train at Thirsk and Sowerby Leisure Centre pool, and have nearly 200 members ranging from four years old to adult. We aim to provide a high standard of coaching and teaching, to train swimmers to compete at League, County and National level, but also for fitness and recreation.

The club has Swim 21 status, which is means we are accredited by the ASA
