While Yorkshire have been stuck on 13 victories since 2001, they remain one of the giants of the ASA National County Team Championships, finishing outside the top three just once in the past 15 years.
They finished second for the 12th time in their history last year, more than 20 points clear of Somerset in third.
Joe Litchfield and Amelia Clynes led by example in the top age group, bringing home maximum points in the 16/17 Yrs 100m Backstroke and 100m Butterfly respectively.
The White Rose have assembled an eye-catching squad to try and break border rivals Lancashire’s dominance of the top flight.
Clynes returns as she aims to win the 16/17 Yrs 100m Fly for the second consecutive year while younger sister Rebecca Clynes won the 100m and 200m Breaststroke double at this year’s British Summer Champs.
City of Leeds also provide big hitters in the form of 2016 European Junior Championship medallist Layla Black, British Summer Champs 200m IM gold medallist Ciara Schlosshan and 13-year old Tia Ward, who won seven individual golds on her British Summer Champs debut in July.
City of Sheffield’s Elliot Clogg also comes into the event off the back of an impressive haul this summer. He landed the 50m, 100m and 200m Backstroke hat-trick, as well as 100m Freestyle gold at the British Summer Champs.
Jonathan Milner, Cameron-Brooks-Clarke, Harry Devlin, Madeleine Dyer and Charlie Brown all also won individual medals at this year’s summer benchmark meet.
