Context paragraphs:
The Colonel (horse): The Colonel (1825–1847) was a British-bred Thoroughbred racehorse and sire best known for running a dead heat in the Epsom Derby and winning the St Leger Stakes in 1828.  In a racing career which lasted from 1827 until 1831, The Colonel ran fifteen times and won ten races at distances ranging from six furlongs to three miles.  Apart from the St Leger, his most notable successes came in the Champagne Stakes, the Epsom Craven Stakes (twice), the Great Park Stakes at Ascot and the Northampton Gold Cup.  He was also placed in both the Ascot Gold Cup and Goodwood Cup.

Al Kazeem: Al Kazeem (foaled 15 April 2008) is a British Thoroughbred racehorse.  He showed promise as a two-year-old in 2010 and became a consistently successful performer in the following year.  In 2012 he won the Jockey Club Stakes on his seasonal debut but was then sidelined by injury for almost a year.  In 2013 he won the Gordon Richards Stakes on his comeback and then took three consecutive Group One races: the Tattersalls Gold Cup, Prince of Wales's Stakes and Eclipse Stakes.  After an unsuccessful spell at stud he returned to racing in 2014 to win the Winter Hill Stakes and finish a close second in the Champion Stakes.  He began his 2015 season by winning the Prix d'Harcourt and went on to win a second Tattersalls Gold Cup before being retired for the second time in August.

Jockey Club Gold Cup: The Jockey Club Gold Cup, established in 1919, is a thoroughbred flat race open to horses of either gender three-years-old and up.  It is typically the main event of the fall meeting at Belmont Park, just as the Belmont Stakes is of the spring meeting and the Travers Stakes is of the summer meeting at Saratoga.  The past winners of the Gold Cup are a veritable who's who of award-winning Hall of Fame horses, including Easy Goer, Man o' War, Cigar, Skip Away, Curlin, Slew o' Gold, John Henry, Affirmed, Forego, Shuvee, Damascus, Buckpasser, Kelso, Sword Dancer, Nashua, Citation, Whirlaway and War Admiral.  Despite the current $1,000,000 purse and Grade 1 status, the stature of the race has suffered somewhat in recent years thanks to the emergence of the Breeders' Cup Classic held not long afterward, as well as a change in distance to 1 ⁄ miles in 1990, reducing its distinctiveness.

Scottish Rifle: Scottish Rifle (28 February 1969 – 1984) was an Irish-bred British-trained Thoroughbred racehorse and sire.  After winning one minor race as a juvenile he emerged as a top-class middle distance colt in 1972, winning the Predominate Stakes, Gordon Stakes and March Stakes as well as finishing second in the Irish Derby.  He reached his peak as a four-year-old in 1973, winning the Earl of Sefton Stakes, Brigadier Gerard Stakes, Westbury Stakes, Eclipse Stakes and Cumberland Lodge Stakes.  He also finished second in the Prince of Wales's Stakes and the Benson and Hedges Gold Cup and ran third in the Washington D C International.  Ater his retirement from racing he stood as a breeding stallion in England and Czechoslovakia but had little success as a sire of winners.  He died in 1984.

2011 Cheltenham Gold Cup: The 2011 Cheltenham Gold Cup was a horse race which took place at Cheltenham on Friday March 18, 2011.  It was the 83rd running of the Cheltenham Gold Cup, and it was won by the pre-race favourite Long Run who beat three previous winners of the Gold Cup in Kauto Star, Denman and defending champion Imperial Commander.  Long Run was ridden by Mr Sam Waley-Cohen and trained by Nicky Henderson.  Waley-Cohen became the first amateur jockey to win the Cheltenham Gold Cup since Jim Wilson on Little Owl in 1981 while Long Run was the first six-year-old to win the race since Mill House in 1963.

Meteora (horse): Meteora (1802–1821) was a British Thoroughbred racehorse and broodmare who won the classic Oaks Stakes at Epsom Downs Racecourse in 1805.  In a racing career which began with her win in the Oaks on 31 May 1805 and lasted until July 1810 she ran thirty-six timeas and won twenty-four races.  She defeated the Derby winner Cardinal Beaufort and the St Leger winner Staveley in match races and won many other important races of the era including the Stamford Gold Cup (three times), the Oatlands Stakes (twice), the Audley End Stakes, the Somerset Stakes and the Brighton Gold Cup.  Many of her defeats occurred when she was carrying large weights in handicap races.

2015 APBA Gold Cup: The 2015 APBA Gold Cup, the 111th running of the APBA Gold Cup race and the 50th running of the local event, was held on July 24, 25, and 26, 2015 on the Columbia River in Kennewick, Washington.  Contested over eight heats and a final on the 2.5-mile (4 km) oval, it was the first points-payin race of the 2015 H1 Unlimited season after the original first race, the Indiana's Governors Cup, was converted into an exhibition event after numerous delays.  Jimmy Shane won the race, his second consecutive and all-time APBA Gold Cup win, the first win of the season, and the third APBA Gold Cup win for Miss Madison.  J. Michael Kelly finished second, while Cal Phipps, Brian Perkins, and Scott Liddycoat rounded out the top five.

Arcadian Heights: Arcadian Heights (14 April 1988 – after 2011) was a British Thoroughbred racehorse who recorded his biggest win in the 1994 Ascot Gold Cup.  He was unraced as a two-year-old but developed into a useful stayer as a three-year-old when he won the Chester Stakes, finished second in the March Stakes and ran prominently for a long way in the St Leger.  In 1992 he failed to win but ran well to take second place in the Ormonde Stakes, Henry II Stakes and Ascot Gold Cup.  His prospects however became compromised by his difficult and aggressive temperament as he attempted to attack other horses during his races.  An attempt to curb his behaviour by fitting him with a muzzle was only partially successful and he was gelded before the end of the year.
