[2] Liam's Map's dam Miss Macy Sue was a successful racemare who won eleven of her twenty-five races including the Grade III Winning Colors Stakes at Churchill Downs in 2007.
On September 26 the colt started favorite for a one-mile maiden at Belmont Park and opened his winning account as he took the lead in the stretch and drew away to come home nine and a half lengths clear of Point Hope.
Liam's Map next appeared in a one-mile allowance race at Aqueduct Racetrack on November 16 and recorded another emphatic win, finishing eleven and a half lengths clear of his six opponents.
[7] The colt was then moved up sharply in class for the Grade I Whitney Stakes over nine furlongs at Saratoga in August and started 5/1 fourth choice behind Tonalist, Honor Code and Lea.
Ridden by Mike Smith, he led from the start and kicked four lengths clear in the straight but was caught in the final stride and beaten a neck by Honor Code.
Shortly before the race it was announced that an interest in the horse had been bought by Lane's End and that Liam's Map would be retired to the Versailles, Kentucky-based stud for the 2016 season.
[10] In the Dirt Mile, Liam's Map started 1/2 favourite against ten opponents headed by Lea, with the others including Red Vine, Wicked Strong, Bradester (Monmouth Cup), Tapiture (runner-up in the race in 2014), War Envoy (Britannia Stakes), Mr Z (Ohio Derby) and Valid.
[11] In the Eclipse Awards for 2015, finished runner-up to Honor Code in the poll for American Champion Older Dirt Male Horse receiving 95 votes to his rival's 126.
[12] After Liam's Map's victory in the Breeders' Cup Mile, Lane's End Farm announced publicly that they had acquired the rights to stand him as a stallion, alongside Eclipse Award nominee Honor Code, beginning in 2016.
