Arkwrisht heads O'Brien quartet for National Arkwrisht is likely to lead Joseph O’Brien’s challenge in the Boylesports Irish Grand National. The nine-year-old’s form this year is not too inspiring, but O’Brien is pinning his hopes on the fact he still held every chance 12 months ago in the race when hampered at the final fence — eventually finishing sixth. O’Brien may run as many as four in the Easter Monday marathon. “Arkwrisht, Vieux Morvan, Slowmotion and Shady Operator would be the ones we have for the Irish National — although the last two mightn’t get in,” said O’Brien. “Arkwrisht was a bit unlucky in it last year, and if he came back to that run he would have a chance. “He would have been right there only for being hampered at the last. He is a good jumper and only fell out of tiredness at Cheltenham on his last start.”
