Risen Star Stakes winner Intense Holiday was euthanized Thursday because of laminitis, an inflammatory disease that ultimately leaves horses unable to walk.

“It’s a tough day for me, our partners and our team,” said Jack Wolf, co-managing partner of Starlight Racing, which owned Intense Holiday. “This horse was a fighter and he fought for his life in the same way he battled on the track — with tenacity. It’s a terrible loss for all of us.”

Trained by Todd Pletcher, Intense Holiday won the Risen Star at the Fair Grounds in February and finished second to Vicar’s in Trouble in the Louisiana Derby. After finishing 12th in the Kentucky Derby, the son of Harlan’s Holiday developed a fracture in his right foreleg while training for the Belmont and was retired following surgery May 27.

Laminitis in both forelimbs was discovered shortly after the surgery, and the condition was deemed irreversible.

Intense Holiday, a dark bay colt out of Unbridled’s Song’s mare Intensify, won twice in nine races and earned $551,900.
