His wife Joy, a former equestrian rider, was diagnosed as terminally ill in November after a colonoscopy revealed that bowel cancer had spread to her liver, lungs and sacrum bone.
But Alligator Blood is giving the Endresz family a reason to smile.
“He means everything [to Joy],” Endresz said.
“We’ve been offered $3.2 million to a gelding, which is an incredible sum of money, but I’d give that up in a flash if we had a cure for cancer today.
“It means a lot that she’s enjoying seeing the horse and our family and the kids, and we’re committed to racing.”
Endresz named the son of All Too Hard with the poker phrase “alligator blood”, “a term that means resilience and never giving up and more importantly, it’s being tenacious,” he said.
The term reflected the trying times Endresz has endured fighting bankruptcy and litigation from the federal government, but has taken on a greater meaning since Joy’s diagnosis.
The definition of alligator blood couldn’t better fit the horse who received the tag.
“Meeting people in the cancer area has been fantastic because it’s resonating with those people are challenged in their lives to just survive and the responses we’ve had from the public has been overwhelming,” Endresz said.
“They love the name. I think losing the Caulfield Guineas has been to our advantage.
“Sadly we have the tall poppy syndrome in Australia and we’ve bypassed that. We got knocked early and the public is supporting him big time.
“As long as they get the message it’s not win or lose, it’s always keep trying and don’t give up and that’s what Al will do.”
Endresz said he was looking forward to what could be the start of a number of rivalries when Alligator Blood clashes with his Kiwi counterpart Catalyst on Saturday.
“He’s a formidable horse [Catalyst], don’t worry about that,” he said.
“For us, it’s exciting to see this come into racing.
“We’ve enjoyed some incredible racing with the mares – Makybe Diva, Black Caviar and Winx – but reflecting on my days as a young fella watching some of the superstar clashes and you were never certain which one was going to win, and we hope that starts something as a benchmark.
“Don’t forget Dalasan and Soul Patch in that race, they’re all good horses, so we’re just going to enjoy it and see what happens.”
