Wylie bubbling over Tidal Bay
Owner Graham Wylie believes Tidal Bay has the enthusiasm and drive to stay in training "for another two seasons".
The 13-year-old gelding will in April bid to become the oldest winner of the Crabbie's Grand National at Aintree since 1923.
But Wylie is convinced retirement has not yet been considered for the Paul Nicholls-trained stayer, who finished runner-up in the Irish Hennessy at Leopardstown on his last visit to the racecourse.
He told The Times: "I see no reason why he shouldn't race for another two seasons.
"He's still very enthusiastic and I know from personal experience that some horses just don't take to standing in a field.
"When we retired Inglis Drever, he was dead within six months, aged only 10, and I'd hate that to happen to Tidal Bay.
"Paul has done a great job with him and I think he will still be capable of winning good races for a while yet."
