Lynwood Gold could revert to the smaller obstacles at the Galway Festival, while his main target on the Flat is the Irish Cesarewitch.
“He’s a good stayer and he likes that bit of ease in the ground. He might run over hurdles in Galway,” said the County Kildare handler.
“The Cesarewitch at the end of the year is probably his aim. How we get to there, I’m not sure.
“I’m delighted with that, because he’d been threatening to do it. I thought the second horse was going to go past him, but he put his head down and came back at him.”
