The 2007 event, held in December, saw 4s included in the Small Boats Head and Durham compete for the first time, dominating the medal table. In 2008 the event was again held in October but moved to the Witham in Boston, Lincolnshire, where it now runs in conjunction with the GB Rowing Team 1st Senior/U23 Assessment.
