1805: three-year-old season

Meteora's racing career was scheduled to begin with a 200 guinea match race against a filly owned by Mr Sitwell at Newmarket on 13 May. She won the prize money without having to compete when her opponent failed to appear for the race. On 31 May Meteora made her competitive debut in the Oaks Stakes at Epsom. In a field of eight she was the third choice in the betting at odds of 7/2 behind the Duke of Grafton's filly Dodona. Ridden by Francis Buckle, she won the classic from Dodona and Sir Frank Standish's unnamed sister to Duxbury.^[3]

Meteora won her remaining five race in 1805. At Ascot in June she won a Sweepstakes over the New Mile course despite carrying a seven pound weight penalty for her win in the Oaks. At the Newmarket July meeting she won a match race against the four-year-old colt Lyncaeus and in August she appeared at Chelmsford in Essex where she walked over for the Gold Cup. At Newmarket in October she won a subscription race over the two mile "Ditch-In" course and a 100 guinea match over the Rowley Mile against Merryman.^[4]

At the same meeting she ran a dead heat when conceding sixteen pounds to Brighton, a horse who went on to win the Ascot Gold Cup in June.^[10] Meteora won her remaining five races of 1808 outright. On 29 June she won a second Stamford Gold Cup, beating Lydia and Clinker. At Brighton in August she won the Somerset Stakes over four miles and the Brighton Gold Cup over the same distance two days later.^[11] At Newmarket she defeated the Duke of Grafton's horse Musician in a subscription race over the Beacon Course on 3 October and Lord Lowther's Brainworm in a similar event two weeks later.
