On 12 December 2015, Extreme Choice made his debut in the $500,000 Inglis Nursery, which horses that were sold at The Inglis Yearling Sales are eligible to enter. The horse won, but had to trial 4 days before the race to qualify. Trainer Mick Price said, "I normally wouldn't do it, but I had to squeeze everything into him between gallops and trials and race day. You've got to have the horse to do it. Shins were good, constitution was good and it was fantastic for the people involved, including myself." Extreme Choice returned in the 1000m Group 3 Chairman's Stakes in February, winning easily. Three weeks later, Extreme Choice won the Group 1 Blue Diamond Stakes, with another Mick Price-trained horse, Flying Artie coming second. In his first race at 1200m, he collected $914,500 in the race for two-year-olds. Price said, "But all credit to Extreme Choice. Today was the day where he had an opportunity to really stand up. I think today we got a lot of information about the horse and we're off to the Slipper." As a result of the win, the horse immediately entered favouritism for the race. In the days before the Golden Slipper Stakes, it was announced that Extreme Choice would be racing in China Horse Club colours after they purchased a controlling interest in the horse in conjunction with Aquis Farm and Newgate Farm. The deal was to see the purchase price raise to 20 million dollars, should Extreme Choice have won the race. Finishing eighth, jockey Craig Newitt said, "I don't think he went 100 metres without getting interfered with the whole race. For him to get as close as he did his run was outstanding." After a spell, Extreme Choice returned in the Group 1 A J Moir Stakes in September 2016. In his first appearance at Moonee Valley, Extreme Choice was said to have "left two of Australia’s greatest sprinters, Chautauqua and Buffering, in his wake with a devastating finishing burst to win". Three weeks later he failed to place in the Coolmore Stud Stakes and was spelled. In February 2017, one owner listed his five percent share of Extreme Choice on bloodstock trading platform G1Xchange.com. With a successful trial under his belt, Extreme Choice was the favourite for Oakleigh Plate in February 2017. Finishing third, a length behind winner Sheidel, Price said, "He ran home well but the two winners were in the right spot – on the speed. He certainly didn’t disappoint." With new jockey Joao Moreira onboard, Extreme Choice then failed to place in the Newmarket Handicap. In March 2017, Extreme Choice was retired to stud, with a stud fee of $22,000 in 2018.
