2009–2010: National Hunt Flat races Rock On Ruby began his career by running in
National Hunt flat races. On his first appearance in a minor event at Newbury in November 2009, he finished fourth to
Oscar Whisky, who went on to win the
Aintree Hurdle in 2011 and 2012. Rock On Ruby recorded his first win on his next start at
Taunton in February, beating Karasenir by three quarters of a length when ridden by his namesake,
Ruby Walsh. On his only other start of the season he beat Karasenir again, this time carrying top weight of 163
pounds in a similar event at Newbury in March.
2010–2011: Novice hurdles Rock On Ruby began the 2010/2011 season by winning his third successive National Hunt flat race, this time at Cheltenham, and was then campaigned in Novice Hurdle races (races confined to horses which have not won over hurdles before the start of the season). He made a successful hurdling debut by winning a race at Newbury in December by six lengths: few details of his victory were reported as the race was run in thick fog. He was then moved up in class to contest the Grade II
Classic Novices' Hurdle at Cheltenham in January. He jumped the last hurdle level with
Bobs Worth but was beaten by two and a half lengths after his jockey dropped his whip 120
yards from the finish. Rock On Ruby was then promoted to the highest level at the
Cheltenham Festival where he ran in the Grade I
Neptune Investment Management Novices' Hurdle over two miles five
furlongs. Ridden by Daryl Jacob, he took the lead at the last hurdle and ran on strongly but was caught "in the last stride" and beaten a short head by First Lieutenant. On his final start of the season, he finished third behind Spirit Son and Cue Card in the
Mersey Novices' Hurdle at
Aintree in April.
2011–2012: hurdles After being campaigned over longer distances as a novice, Rock On Ruby was brought back in distance on his first race of the 2011/2012 season. Running over two miles in the Gerry Feilden Hurdle, a
handicap race at Newbury, he carried top weight of 164 pounds and won "readily" by six lengths from his stable companion Empire Levant, to whom he was conceding 24 pounds. Following this win he was strongly fancied for the Grade I
Christmas Hurdle at
Kempton Park and started 7/4 second favourite behind the 2010
Champion Hurdler
Binocular. Rock On Ruby took a slight lead at the second last hurdle and looked the likely winner but after what the
Racing Post described as a "thrilling battle", finished second to Binocular, beaten a neck at level weights. In the 2012 Champion Hurdle at Cheltenham on 13 March, Rock On Ruby started 11/1 fourth choice in the betting, behind the reigning champion,
Hurricane Fly, Binocular, and Zarkandar. From the start of the race, Rock On Ruby, ridden by Noel Fehily, tracked the leader,
Overturn, and then moved up to dispute the lead two hurdles from the finish. He took a decisive advantage turning into the straight and ran on strongly under pressure, showing what the
Daily Telegraph described as "tremendous courage" to win going away by three and three quarter lengths from Overturn, Hurricane Fly, and Binocular. On his final start of the season, Rock On Ruby was sent to Liverpool for the
Aintree Hurdle on 14 April. He led until being overtaken at the second last hurdle and finished third to Oscar Whiskey and Thousand Stars.
2012–2013: hurdles For the 2012/2013 National Hunt season, Rock On Ruby was officially trained by Harry Fry, who was now operating independently from Nicholls. He made his first appearance for his "new" trainer in the International Hurdle at Cheltenham in December when he finished third behind
Zarkandar and Grandouet. Rock On Ruby had his trial race for his second Champion Hurdle in the 32Red Hurdle at
Doncaster Racecourse in February in which he was matched against the
Triumph Hurdle winner Countrywide Flame and the
Nicky Henderson-trained Darlan, who had been favourite for the championship since winning the
Christmas Hurdle. Rock On Ruby took the lead at the last hurdle and won by three lengths, but his victory was overshadowed by the death of Darlan, who was fatally injured in a fall at the last. At Cheltenham on 12 March Rock On Ruby started the 11/2 third favourite for his second Champion Hurdle. He led the field until the second last hurdle before being overtaken and beaten two and a half lengths by Hurricane Fly. On his final appearance of the season, he was sent to Ireland where he finished third to Hurricane Fly and Thousand Stars in the
Punchestown Champion Hurdle.
2013–2014: Novice chases Rock On Ruby began the new National Hunt season in a hurdle race at Kempton in October in which he finished second, ten lengths behind
The New One. On 16 December, the gelding ran in his first
steeplechase when he started 1/10 favourite for a minor
Novice race at
Plumpton Racecourse and won "very easily" by four lengths. Only one horse, the Nicolls-trained Mr Mole appeared to oppose Rock On Ruby when he warmed up for the 2014 Cheltenham Festival in a novice chase at Doncaster on 9 February. Rock On Ruby led from the start and, despite two minor jumping errors, won by ten lengths. On 11 March, he started the 5/1 for the Grade I
Arkle Challenge Trophy over two miles at Cheltenham. He made a very bad mistake at third fence, almost unseating Fehily, who dropped his whip. He never recovered and came home last of the eight finishers behind
Western Warhorse. The gelding returned to hurdling in the
Aintree Hurdle on 3 April. Starting at odds of 10/1 he took the lead at the eighth hurdle but was overtaken by the odds-on favourite
The New One after the second last obstacle. He rallied strongly after the last but was unable to overhaul The New One and finished second, beaten a head by the winner. After the race, Harry Fry said that he was "thrilled to bits" with the performance and announced that the horse would be returned to hurdling permanently, with the 2015 Champion Hurdle as his principal objective.
2014–2015: hurdles On his first appearance of the new season, Rock On Ruby finished third in the
Elite Hurdle at Wincanton on 8 November, conceding thirteen pounds to the winner Purple Bay. On 13 December he started favourite for the Relkeel Hurdle at Cheltenham and recorded his first hurdle win in twenty-two month as he defeated the five-year-old Volnay de Thaix by two and a quarter lengths. Four weeks later the gelding added a win in the Dornan Engineering Hurdle over the same course and distance, beating Vaniteaux and
Cole Harden by two and a half lengths and a neck. He was trained for the
World Hurdle at the Cheltenham Festival but was withdrawn a week before the race after contracting a respiratory infection. Rock On Ruby returned in the Aintree Hurdle on 9 April in which he started third choice in the betting behind
Jezki and the Champion Hurdle runner-up Arctic Fire. He raced in second before taking the lead at the second last but was badly hampered when Arctic Fire fell at the final hurdle and finished second, thirteen lengths behind Jezki.
2015–2016: hurdles On 21 November 2015, Rock On Ruby started second favourite on his first start of the season when carrying top-weight in the
Ascot Hurdle. He travelled well and looked to be overtaken in the home straight but after a major jumping mistake by one of the threatening rivals, Rock On Ruby managed to find more and extended at the line to win by two and half lengths. Less than a week later on 27 November, trainer Harry Fry announced that Rock On Ruby has been retired following a tendon injury that he suffered when winning the
Ascot Hurdle. Fry explained the decision to retire the ten year old: "if he was a younger horse we might have considered treating the injury and bringing him back a year or more later". ==Pedigree==
