Having been ridden in his first four races by the amateur Ben Pollock, Teeton Mill was partnered by Seamus Durack when the gelding contested a hunter chase at Cheltenham Racecourse in April 1998.
A month later Teeton Mill was ridden by Shirley Vickery when he contested the Horse & Hound Cup Champion Hunter Chase over three and a half miles at Stratford Racecourse.
On his seasonal debut, he carried 158 pounds in the Badger Beer Handicap Chase over three and a quarter miles at Wincanton Racecourse on 7 November and won by eight lengths from Menesonic.
He was eased down in the closing stages to win by four lengths from Senor El Betrutti with the subsequently disqualified Challenger du Luc in third place.
