build withstands competition better than light trotters, and the breed's effective competition career can be very long. The Finnish harness racing bylaws allow Finnhorses to be raced from ages 3 to 16. For a "coldblood" breed, the Finnhorse is quite fast. The official Finnish coldblood record from 2010 is 19,9aly, was long held by the quintuple Finnhorse racing champion stallion Viesker, but was finally broken by Jokivarren Kunkku in 2015 (19,5x) The coldblood horse world record in harness racing was long held by Finnhorses, until in 2005 the record was broken by Järvsöfaks, a Scandinavian coldblood trotter from Sweden. As of 2010, the official Finnish record for mares, and the world record for coldblood mares, is 20.2aly, held by the double Finnhorse racing female champion I.P. Vipotiina. The absolute Finnhorse speed record is 19.4aly, held by the stallion Sipori. As the result was not achieved from a win, the time is not an official Finnish record. Finnhorses have been so successful against other coldblood trotter breeds of Scandinavia, that by the 21st century, they have been admitted to Swedish and Norwegian races only by invitation. Some conformation flaws common in the breed that may hinder a trotter's success include a heavy forehand and overangulated hind legs. Another problem that affects some Finnhorses is a tendency to trot with the front and hind legs directly in line with other, which creates a high probability of forging, where the hind hooves hit the front pasterns, which can cause breaking gait. This can be helped to a degree with careful shoeing. There is also a tendency toward ossification of the hoof cartilages of the front feet, which tends to increase with age, and appears to be heritable. This condition, called sidebone when it affects the lateral and medial cartilages of the foot, is common in draught breeds. However, a study of affected Finnhorses also noted that horses with long toes and low heels were common and ossification correlated with the length of the heels. Riding horse type The riding horse section Finnhorse is a capable and reliable mount. It lacks some traits required for competing at the highest levels of international riding sports, but its combination of size and good temperament makes it suitable for both adults and children. To qualify for the riding section, a horse must carry itself well, and have a long neck, small head, sloping shoulder and well-defined withers.
