The race was contested by only 5 runners, including Hokkaido Sansai Stakes winner Hishi Speed [ja], who had almost caught up to Maruzensky in the race due to Nakanowatari not anticipating any other horse to catch up to him, and had let the horse run slowly.
His time, 1:34.4, was a course record that would not be broken for 14 years until Lindo Shaver [ja] broke it in 1990.
[9][10] After the race, Nakanowatari commented that "he couldn't even hear the footsteps of the other horses" past the 3rd corner.
[11] Hishi Speed's jockey, Futoshi Kojima [ja], commented "That thing is a monster... To be honest, I'm glad I won't have to deal with [Maruzensky] for a while" regarding the winner of the race.
[13] Maruzensky started off the season with an open race held at Chukyo Racecourse with the intention of running in the Kisaragi Sho.
[12] The open race was almost canceled were it not for Masatoshi Hattori [ja] entering two of his horses under his training.
[5] Maruzensky being barred from entering the Derby caused controversy within the horse racing circle of Japan, with the official JRA magazine, Yushun, even holding a discussion panel on its September 1977 issue.
[15] On June 26, Maruzensky was entered in to the Nihon Tampa Sho, where nearly 80,000 people attended to see the horse run.
Initially, there were plans of Tosho Boy [ja] running in that race alongside Maruzensky.
[8] In the race, a filly named Yoshio Kazan took the lead and made Maruzensky run from the 2nd of the pack, which was a first for the horse.
[18][19] Upon retirement, Maruzensky was sent to the Toyosato Stallion Center in Monbetsu, Hokkaido to stand stud there.
[22] A funeral was held three days later on August 24, attended by many people as well as his dam, who was still alive at the time, before being buried inside the Hashimoto Bokujou property.
