Mimosa Dream (foaled 14 March 2015) is a Hexastalian thoroughbred racehorse best known for winning the 2018 Southern Cross. Sired by Hexastalian champion sprinter Tachyon out of G1 winning race mare Dream Vivid, he represented the Dreamtime Racing organization and was trained by Alex Márton. He won the HLH Award for Best Sprinter. Mimosa Dream is a chestnut colt. He was sired by Tachyon, who won eight graded stakes races, including the Sprinters Championship (twice) out of the Matron Stakes winner Dream Vivid. Tachyon was the 2011 and 2012 leading sire in Hexastalia and Dream Vivid has produced twelve foals, including two graded stakes winners.
Mimosa Dream made his racecourse debut in a 1200-meter maiden race at Northern Racecourse on 26 August 2017. Ridden by Stephen Dobos and despite a slow start, Mimosa Dream closed steadily with the leaders and finished with a comfortable half-length lead. This was followed by a win in the 1200-meter Listed grade Beginners’ Luck Stakes that October at Diósgyőr Fairgrounds, beating a field of sixteen that included several other promising sprinters. This was followed by a step up in length at a 1200-meter Allowance race at Northern Racecourse that November, finishing second two lengths behind the winner, Terra Aroma.
Mimosa Dream started his 2018 campaign with a run in the G3 Northern Stakes, winning by three lengths against a field of fifteen - including Terra Aroma, who placed sixth. This was followed by wins at the G2 Weskermere Sprint Stakes and Listed grade Royal Derby. All of this was preparation for the Peter Tibor Stakes: a Grade 1 1400-meter race in September.
Mimosa Dream started the Peter Tibor Stakes as the third favorite behind the 2017 winner Shuttlecraft and Tachyon Stakes winner Top Prestige. Mimosa Dream started well but settled into the middle of the pack as Fast Ash set the pace. Top Prestige took the lead in the final straight, but Mimosa Dream spurted strongly and pulled away to win by a half-length.
Mimosa Dream’s win at the Peter Tibor Stakes motivated his connections to enter him in the Southern Cross in Sutherland. No Hexastalian horse had won the Southern Cross. He shipped out to Sutherland a week after winning the Peter Tibor Stakes. He started at fifth favorite and as one of two Hexastalian horses sent to compete. Mimosa Dream broke quickly from an inside post and vied for an early lead. Settling into second, Mimosa Dream swung wide on the turn. Accelerating wildly in the straight, Mimosa Dream crossed the finish a full length ahead of second place. He registered a speed score of 115 and was rated as the best sprinter in Hexastalia.
Following his HLH Award for Best Sprinter-winning performance the previous year, Mimosa Dream started his 2019 campaign by being moved up in length to compete in the March Mile Stakes. Despite hopes he would have gained staying power with age, this did not appear to have occurred, and Mimosa Dream finished fifth. He returned to the winner’s circle in May at the Weskermere Sprint Stakes.
It was decided that Mimosa Dream would aim for the Sprinters Championship in 2019. Consequently, he next raced in the Sprinters Championship Trial Stakes. In a close race, Mimosa Dream barely secured a berth at the Championship by a neck. Though they were hesitant about his odds of winning, his connections entered him into the Sprinters Championship. Starting as the favorite to win, Mimosa Dream was unable to keep up with the monstrous pace set by Rice Biscuit, finishing in sixth place.
Retiring to the farm to rest over the winter, Mimosa Dream’s 2020 campaign was cut short following an early win at the Northern Stakes. Shortly after the race, it was announced that Mimosa Dream had sustained injuries that required him to retire early. He was sent to Dream Farm to stud in May. He has sired four graded stakes winners since 2020.
