Le Marmot was a bay horse with a white sock on his right hind leg bred in France by the Marquis de Talhouet Roy.
On 8 October, Le Marmot started second favourite for the Group One Grand Critérium over the same course and distance but dead-heated for eighth place, six lengths behind the winner Irish River.
[4] After a break of three months, Le Marmot returned for the Prix Niel at Longchamp on 9 September, when he faced Top Ville for the second time.
In a closely contested finish he prevailed by a neck and head from Fabulous Dancer and Kamaridaan, with Top Ville a length and a half further back in fourth place.
Starting at odds of 4.6/1, he overtook Northern Baby early in the straight and won decisively by one and a half lengths from the 3/10 favourite Three Troikas.
[6] In July, Le Marmot was sent to England and started favourite for Britain's most prestigious weight-for-age race, the King George VI and Queen Elizabeth Stakes over one and a half miles at Ascot Racecourse.
Despite his position in the betting, the colt was not at his best, having had an injury in training which disrupted his preparation and then picking up a knock to his hock when being shipped from France: Paquet was under instructions to withdraw the horse if he showed any sign of lameness before the start.
In the official International Classification, Le Marmot was rated the best three-year-old colt in France and the fourth-best horse of any age in Europe behind Three Troikas, Troy and Ile de Bourbon.
[6] Le Marmot was retired from racing to become a breeding stallion at the Haras du Petit Tellier but died 1981, during his first season at stud.
