Catherine's Well was bred foaled in 1983, a bright chestnut filly by Junius. She made her racecourse debut as a two year old and proved she had bags of speed. She won her first race at Doncaster in September 1985 and the same season also won at Newmarket and again at Doncaster later in the year. Her biggest win came at Ripon in her three year old season when she won the Great St Wilfrid Handicap, a season which also saw her win at Beverley, Newcastle and Newmarket.
Catherine's Well had won seven races when she was then retired to the paddocks but she failed to produce a winner from her first three foals. She returned to training in 1991, but her second career didn't start well as she was left at the start in her first race at Ripon in April 1991. However, she soon got back into the racing game and that season she won at Catterick and Ripon.
Catherine's Well raced for another two seasons winning again at Doncaster (twice), Catterick, Thirsk and York. In all she managed to win seven races between her first and her second retirements.
Returning to the paddocks, her second spell as a broodmare was a huge success and she will be remembered as a brilliant broodmare in her later career as well as a 14 times winner. She was to be the dam of many winning sprinters including Williams Well who also went on to win the Great St Wilfrid Handicap in 2000 and other multiple winners including Emperor's Well and Elvington Boy.
