I was reading about the Cheltenham Festival which started today and ran across an article about Altior. He has won 17 straight jumps races (mostly G1s and other group races), including the Arkle and the Champion Chase at Cheltenham at 3,200 meters. He’s been racing since he was 4 and is now 9; his overall record is 20 starts, 18 wins and 1 third, and hasn’t lost since 2015. He was out with “wind surgery” for half of 2017, but still didn’t lose before or afterwards. By the Brits, he’s called “only 9”, so apparently is believed to have more years to race.
He’s won a race by 63 lengths, and several by more than ten lengths.
He runs in the Champion Chase at Cheltenham tomorrow, and if he wins he will equal the record for longest winning streak in jumps racing history.
I’d say a 17 race winning streak over jumps at 3200 m ( just under 2 miles) puts him in the top ranks of any racing horses anywhere today, even if he doesn’t win tomorrow.
