2019: two-year-old season

Honor A. P.'s first race was on August 17, 2019, at Del Mar Racetrack, where he finished second. In his second race on October 13, he scored a win at Santa Anita in a maiden special weight over one mile on the dirt track.^[2]

2020: three-year-old season

Honor A. P. started his 2020 season on March 7 at Santa Anita in the San Felipe Stakes, one of the traditional prep races on the Road to the Kentucky Derby. He rated in fourth place behind the early leaders and then closed ground to finish second behind Authentic. He earned a solid Beyer Speed Figure of 95 for the race, establishing himself as a serious contender for the Derby. However, Santa Anita was shut down shortly after the race due to the COVID-19 pandemic, while the Kentucky Derby wound up being rescheduled to September.^[7]

On June 6, Honor A. P. returned in the Santa Anita Derby, where he was the second betting choice at odds of 2-1 behind Authentic. He again rated behind the early pace in a tightly bunched pack, then started his move on the final turn while swinging four wide. He hit the lead in mid-stretch and continued to draw away to win by 1+1⁄2 lengths. Shirreffs was happy with the effort. "We knew that he has tactical speed", he said, "and [jockey Mike Smith] can put him pretty much where he wants. On the backside, we hoped he would get comfortable to have a nice little kick in the end, and it all worked out well."^[8]

Honor A. P. made his next start in the Shared Belief Stakes on August 1. In a field that scratched down to just four horses, he went off as the prohibitive 1-5 favorite. He and the horses on either side of him bumped each other at the start, then chased after early leader Thousand Words in a tight pack. Honor A. P. dropped back a bit on the backstretch then started to improve position on the far turn. However, he could not get by Thousand Words, who won by three-quarters of a length.^[9]

The 2020 Kentucky Derby had been rescheduled from May 2 to September 5. Of the seventeen horses that went to post, Honor A. P. was the second betting choice at odds of 5–1. Tiz the Law was the heavy favorite based on wins in the Belmont Stakes, Travers Stakes and Florida Derby. Authentic went to the early lead and was able to slow down the pace after a fast opening quarter-mile. Honor A. P. broke slowly and was near the back of the field, some 13 lengths behind Authentic after half a mile. He gradually started to improve position on the turn but was still in ninth place with seven lengths to make up with a quarter-mile remaining. He kept grinding away and closed to finish fourth behind Authentic.^[10][11] Smith said that the colt had not adjusted to the racing surface at Churchill Downs. "He spun out from the word go," said Smith. "Really did."^[12]

It was later discovered that Honor A. P. had pulled a tendon during the race, resulting in his retirement.^[13]
