The remarkable 9-year-old Cirrus des Aigles starts in the longest race of his career in Sunday’s $385,000 Prix Royal-Oak at about 1 7/8 miles on turf at Saint-Cloud Racecourse in Paris. Trained by Corinne Barande Barbe, Cirrus des Aigles has won 22 of 65 starts in his career.

Cirrus des Aigles is part of a field of 13 in the Group 1 Prix Royal-Oak, which has been transferred from Longchamp Racecourse while that course undergoes a redevelopment of its grandstand. Longchamp is scheduled to reopen in 2017.

The 2-year-olds Foundation and Deauville might be stuck racing against each other for a while.

They were first and second in the Group 2 Royal Lodge Stakes at Newmarket Racecourse in England on Sept. 26 in their first meeting and are the first two choices with many bookmakers for the English Derby in June.

For their expected final starts of the year, Foundation and Deauville are the top two choices in Saturday’s Group 1 Racing Post Trophy for 2-year-old colts and fillies at Doncaster Racecourse. Geldings are excluded from the race.

Highland Reel, winner of the Grade 1 Secretariat Stakes at Arlington Park in August, is a moderate favorite to win Saturday’s $2.16 million Cox Plate at Moonee Valley Racecourse in Australia.

The Cox Plate is run at 1 1/2 miles on turf and is Australia’s top weight-for-age race. The Group 1 Cox Plate could produce a few runners for the Melbourne Cup on Nov. 3, Australia’s most popular race.

Mikki Queen, winner of the Japanese Oaks in May, won her second major stakes for 3-year-old fillies in Japan in Sunday’s $1,548,614 Shuka Sho at Kyoto Racecourse, a win that solidified her status as the leader of the division.

Ridden by Suguru Hamanaka for trainer Yasutoshi Ikee, Mikki Queen, the 2-1 favorite, set a track record of 1:56.90 for about 1 1/4 miles on turf. Mikki Queen raced in midpack before overcoming a touch of trouble on the turn. Mikki Queen took the lead in the final sixteenth and won by a neck over the 13-1 Queens Ring.

Mongolian Khan and Trip to Paris strengthened their claims as leading contenders for the Group 1 Melbourne Cup on Nov. 3, with a one-two finish Saturday in the $2.17 million Caulfield Cup at about 1 1/2 miles on turf at Caulfield Racecourse in Australia.

Mongolian Khan, the 4-1 favorite, won the Group 1 Caulfield Cup by a half-length over the 30-1 Trip to Paris, leading for the final quarter-mile. Mongolian Khan won the Group 1 Australian Derby in April. Trip to Paris won the Group 1 Gold Cup at Royal Ascot in June.

Fascinating Rock, a 10-1 shot ridden by Pat Smullen, rallied between horses in the final quarter-mile to win the richest race of his career in Saturday’s $2,066,386 Champion Stakes at Ascot.

Solow won his ninth straight race and capped a perfect 2015 campaign Saturday at Ascot with a three-quarter-length win over Belardo in the Group 1 Queen Elizabeth II Stakes.

Trainer Freddy Head, who sent Charm Spirit out to victory in 2014, won his second straight QE II, while Solow solidified his position as the best miler in Europe if not the world this year.

After wins in Grade 1 races earlier this year, Let’s Go Donki and Mikki Queen will try to rebound from recent losses when they start in Sunday’s $1,548,614 Shuka Sho for 3-year-old fillies at Kyoto Racecourse in Japan.

They lead a field of 18 in the race at about 1 1/4 miles on turf, which could provide a few runners for the Japan Cup at Tokyo Racecourse on Nov. 29.

Solow burst onto the international stage with a powerful victory in the rich Dubai Turf in late March, and he can grandly step off it – still unbeaten this year – by winning the Group 1 Queen Elizabeth II Stakes on Saturday at Ascot.

For a second-stringer, Jack Hobbs has put together quite a season in 2015.

Trained by John Gosden, Jack Hobbs won the Irish Derby in June but was second to stablemate Golden Horn in the English Derby earlier that month. Golden Horn later won the Prix de l’Arc de Triomphe and is bound for the Breeders’ Cup Turf at Keeneland on Oct. 31.
