Also, in 2005, Aspell won the Grade I Champion Four Year Old Hurdle at Punchestown Racecourse on the Lucy Wadham-trained mare United.

In July 2007, Aspell announced his retirement from race riding, and left to work for trainer John Dunlop in Arundel.

Aspell's victory makes him the first back-to-back Grand National winner in over 40 years since Red Rum with rider Brian Fletcher, and only the third since World War II, along with Bryan Marshall.
