i don't particularly like hyphenated domains, but this one seems to need the hyphen (Arabic speaker please advise).
Hoping that maybe this could have some interest in the future, I am still holding out some hope

HORSE RACING IN THE MIDDLE EAST
Some of the world’s best equine genes reside in this arid part of the world. The horse and the Middle East can never be separated, and the sport of modern horse racing becomes increasingly reliant on Middle East patronage by the year. Interest in horse racing may wax and wane in other parts of the world, but no place can match the racy and sustained passion for the sport which is found in the Middle East.
Bahrain has made commendable contributions to horse racing in the recent past, but it is to Dubai that most credit is due for the bulk of the region’s contribution to the sport. The Emir from the ruling family has spread his influence on horse racing far beyond the shores of the United Arab Emirates, and has made enormous and continuous investments in U.K. horse racing. Some of the best breeding and racing facilities in and around London are now owned and operated by the Emir and by members of his extended family. This comes in the wake of decades of love for the sport by the Aga Khan, whose stables continue to produce thoroughbreds of rare pedigrees every year. (more in the link) END QUOTE

Horse Racing in the Middle East
In recent years, the horse racing industry in the Middle East has grown impressively. This region is now home to some of the finest racecourses and richest prizes in the sport. It is popular with owners looking for huge prizes, and spectators keen to find attractive odds.
If we look at the example of Dubai, we can see that the stunning Meydan Racecourse was opened in 2010, as a sleek replacement for the Nad Al Sheba Racecourse that once stood there. It has capacity for more than 60,000 spectators and the grandstand is more than a mile long. The work on this stadium is said to have cost $1.25 billion, making it the most expensive racecourse in the world. As well as the racetrack, the Meydan development includes a 5-star hotel, museum, and golf course.
Among the most noteworthy races held here is the Dubai World Cup, which occurs at the end of March annually. A $12 million purse makes this the world’s richest horse race, surpassing by far the Kentucky Derby betting prizes. Other races that place in this part of the world include the Dubai Sheema Classic and the Jebel Hatta, with Abu Dhabi also being home to several important races.
While Dubai arguably now has the best horse racing on the planet, it is worth remembering that Bahrain has also played a big part in the sport. Indeed, the inaugural Bahrain International Trophy was run at the end of 2019 and was won by Royal Julius. END QUOTE
