Arrogate traveled more than 8,300 miles from California to chase the all-time thoroughbred earnings record. His 1¼-mile journey in Saturday’s $10-million Dubai World Cup was far more eventful.

The reigning Horse of the Year was banged hard on both sides and broke last in a field of 14, then was hung eight-wide, 10 lengths behind, on the backstretch, and bumped in upper stretch. None of that mattered, because Arrogate was unstoppable. The gray 4-year-old colt surged four-wide in midstretch and beat Gun Runner by 2¼ lengths at Meydan. Neolithic was a distant third.

In North America, an assistant starter stands in the gate with a horse. In Dubai, not so. Arrogate, taken out of his routine, was unprepared for the start.

“I missed the break completely,” Mike Smith said, “but I had so much confidence in this horse, I just decided I would ride him like [Hall of Fame mare Zenyatta]. This horse can do anything. My outrider said he’s never seen anything like that.”

Neither had anybody else who watched the 1-20 favorite overcame the most troubled trip of a certain Hall of Fame career. He just doesn’t get tired.

His seventh win in eight starts, in the world’s richest race, was worth $6 million, raising his bankroll to $17,084,600 for Juddmonte Farms. The son of Unbridled’s Song paid $2.10 after being timed in 2:02.15 on a drying-out track. It was trainer Bob Baffert’s third World Cup win.

“When he missed the break, I gave him no chance at all,’’ Baffert said. “I was mad at myself for bringing him here. That’s the greatest horse I’ve ever seen run. I can’t believe he won.

“When they turned for home, I said, ‘If he wins, this is the best horse we’ve seen since Secretariat.’ ”

LI trainer gets first win in $2M race. Trainers never forget their first winner, even a cheap claimer at an obscure track. No one could ever top what 32-year-old Bellmore native Chad Summers did Saturday, when he broke his maiden with Mind Your Biscuits in the $2-million Golden Shaheen in Dubai.

Winner’s share: $1.2 million.

The Bellmore JFK graduate took out his trainer’s license only four months ago. He was 0-for-4 with two seconds and earnings of $29,020 before the 4-year-old New York-bred colt rallied to win by 3 lengths under Joel Rosario. He paid $5.60 after a muddy 6 furlongs in 1:10.61.

Summers, a former bloodstock agent, groom and journalist, also co-owns the horse with his father, Scott, and others.

“It’s a storybook ending,” Summers said of his storybook beginning. “I think he’s the best sprinter in the country, in the world. He proved it today.’’

Fast and Accurate wins Spiral. If you like betting gray long shots in the Kentucky Derby, meet Fast and Accurate, who rallied for Tyler Gaffalione to win the $500,000 Spiral Stakes at Turfway Park and paid $51. Dr. Kendall Hansen owns the colt, who isn’t nominated to the Triple Crown, so he would have to pay a $200,000 supplementary fee to run in the Derby. When asked if he’ll go, Hansen said, “Yeah!”
