Horse racing is one of the sports with a long history. It has existed for many centuries, as early as the two-wheeled chariot race in the Roman Empire, and the war horse race recorded in Norse mythology.
Horse racing is still very popular all over the world. This kind of racing competition is naturally easily linked to gambling. There are many horse racing fans around the world, and the amount of betting for each race is very huge, and outstanding horses can win a lot of money for horse owners, so many countries regard horse racing breeding, training and competition as important economic activities.
Flat horse racing is one of the mainstream events in the world. Usually the race distance is from 1000 meters to 2400 meters. Track surfaces vary, with turf most common in Europe and dirt more common in North America and Asia.
Jump racing, originated in the UK, and developed globally. Horses need to jump off the designated number of hurdles, and the race distance is more than 2000 meters.
Harness racing began to be popular in Europe (not including Ireland and the United Kingdom) in the 19th century, and it is more popular than flat horse racing. The track is mainly dirt, and the distance is from one mile to two miles.
