Trainer Gavin Cromwell hopes Raz De Maree can handle the early gallop in Saturday's Randox Health Grand National at Aintree.
Winner of the Coral Welsh National at Chepstow in January, the 13-year-old stay every yard of the trip on Saturday and the forecast rain isn't a concern either.
"They go off very quick and the key thing is whether he can stay in the race or not. As long as he doesn't get detached he'll be fine. He's very slow. But the more of a test of stamina it is the better because he doesn't know how to stop," Cromwell told the Irish Times.
"It comes down to each horse's enthusiasm, and soundness. Raz De Maree is a very sound horse. He's also relatively lightly raced and he's still very enthusiastic. We seem to be getting a good old tune out of him. He's definitely as good now as I've ever had him. But I can't put it down to anything beyond that."
Raz De Maree is currently 40/1 with Sky Bet (non-runner/no bet, five places and Best Odds Guaranteed) for the National.
