Mind you, no horse has ever won the Newmarket without being exceptional, combining speed with stamina to triumph down the famous Straight Six track. When the New Zealand mare Roch ‘N’ Horse won the 2022 Newmarket, her odds were 100–1, even though she had been runner-up in the previous year’s Black Caviar Lightning Stakes. If there was any doubt about her class, she proved herself during the 2022 Melbourne Cup Carnival, prevailing at weight-for-age against the best company to win the VRC Champions Sprint.
The heaviest weighted horse ever, bar one, to win the Newmarket was magnificent Bernborough in 1946, defeating a huge field. He carried 9 stone 13 pounds (about 63 kg) and powered from back in the pack to get up at the finishing line.
Those who saw that performance never forgot it. But the all-time weight-carrying record in the Newmarket (10 stone 2, or 64.4kg) belongs to Greenline in March 1930. He won on the very day when the three-year-old Phar Lap at odds-on took the VRC St Leger in a canter, by five lengths, and their mutual rival, Amounis, won the weight-for-age Essendon Stakes of 1¼ miles, his seventh successive victory. It was a Super Saturday for Sydney jockey Jim Pike, who rode all three of them.
