2017: two-year-old season Marianafoot was ridden in both of his races as a two-year-old by Nicolas Perret. On his racecourse debut in the Prix de la Minadriere over 1400 metres on
good to soft ground at Vichy Racecourse on 18 July he started at odds of
10.6/1 and won by half a
length from Dark Side. On 2 September the colt started 11/10 favourite when he was stepped up in distance for the 1600 metres Prix des Cadets on the synthetic
Polytrack surface at
Cagnes-sur-Mer Racecourse and won again, beating the
filly Ballet de la Reine by one and a half lengths.
2018: three-year-old season Marianafoot began his second campaign by finishing fifth over 1600 metres at Lyon-Parilly and then, with Perret in the saddle, won over 1400 metres on very soft ground at Toulouse on 1 June. In the summer he ran twice over 1200 metres at
Deauville Racecourse running third in the
Listed Prix Kistena in July and fourth when odds-on favourite for the Prix de la Huderie in August. Before his next start the horse was transferred to the training stable of Jerome Reynier. On his first run for his new trainer Marianafoot started 1.6/1 favourite for the Prix Jean de Tauriac over 1400 metres at Toulouse on 3 October and won by four and a half lengths from Diamond City. On the polytrack at Deauville on 16 December the colt started 3.8/1 second favourite for the Listed Prix Luthier over 1500 metres. Ridden by
Pierre-Charles Boudot he recorded his first major win as he produced a strong late run and won by a head from Indyco.
2019: four-year-old season In early 2019 Marianafoot was sent to race in
Qatar and on 22 February he was ridden by Boudot to a neck victory in the Irish Thoroughbred Marketing Cup over 1600 metres at Doha Racecourse. On his return to Europe the colt ran four times in high-class races over 1400 metres at Longchamp. He finished fifth to Hey Gaman in the
Prix du Palais Royal in May, second to
Polydream in the
Prix de la Porte Maillot in July, fourth to City Light in the
Prix du Pin in September and eleventh behind
One Master in the
Prix de la Foret in October. On his final run of the season he went off the 2.1/1 favourite as he attempted to repeat his 2018 success in the Prix Luthier at Deauville on 14 December. With Barzalona in the saddle he prevailed by one and three quarter lengths from Stunning Spirit with Indyco a further two and a half lengths back in third.
2020: five-year-old season In February 2020 Marianafoot returned to Qatar for a second run in the Irish Thoroughbred Marketing Cup but was beaten a short head into second place by Stunning Spirit, sustaining a joint injury in the process. He was off the track for more than nine months before returning to action in the Prix Flying Water over 1300 metres at Deauville in December. Ridden by Antonio Orani, he started the 1.2/1 favourite and won by half a length from Buridan.
2021: six-year-old season Marianafoot began his 2021 campaign with three races on polytrack. He made his first appearance as a six-year-old on 15 January when started odds on favourite for a minor race over 1500 metres at Marseille Pont-de-Vivaux Racecourse where he was ridden by Orani and won by two and a half lengths from J'Aurais Du. He went on to win the 1300 metre Prix Cirrus Des Aigles by three and a half lengths at
Cagnes-sur-Mer in February and the Prix du Bat l'Eau over the same distance at
Chantilly Racecourse in March. On 26 April Marianafoot was stepped back up to Listed class and returned to the turf for the Prix Servanne over 1200 metres at Chantilly and started the 2.5/1 second favourite in a nine-runner field. Ridden by Barzalona he recorded his fifth win in a row as he came home two and a half lengths clear of the favourite Queen of Love. On 30 May at Longchamp Marianafoot made his second attempt to win the Prix du Palais-Royal, and went off the 1.9/1 second favourite behind the
Prix du Muguet winner Duhail. Barzalona sent Marianfoot into the lead after 400 metres and the horse stayed on well to beat Duhail by a length. After the race Jerome Reynier said "Marianafoot is a lovely horse, but... he had to take it easy for nearly all of last year. But he came back maybe better than ever and we are very happy to win... He can stretch to a mile if there is enough pace, but his ideal trip could be the
Prix Maurice de Gheest, six and a half furlongs on a straight course and that is why we tried him last time over the straight course at Chantilly. He has done it well so he is in great shape and we need to keep him like that to try to win a Group 1 with him.” On 1 July, over the same course and distance, Marianafoot started 1.5/1 favourite ahead of Duhail in the Prix de la Porte Maillot on very soft ground. He led from the start, went clear of his opponents 200 metres from the finish and won by one and a half lengths from Duhail despite being eased down by Barzalona in the final strides. In the Group 1 Prix Maurice de Gheest over 1300 metres on soft ground at Deauville on 8 August, Marianafoot was partnered by Barzalona and went off the 8.9/1 third choice in the betting behind the joint-favourites
Campanelle and
Starman. The other nine contenders included
Brando (winner of the race in 2017),
Glen Shiel,
Laws of Indices and
Thunder Moon. After being restrained towards the rear of the field in the early stages Marianafoot began to make rapid progress entering the last 400 metres, overhauled Starman 150 metres from the finish and won by one and three quarter lengths. After the race Reynier said: "The plan really worked beautifully. Over this distance we wanted to attack in the final 100 metres because we know he stays further and some of the others are pure sprinters. We won't rush to decide [on his next race], but he'll stay up here and he could run in the Prix Jacques le Marois, depending on how he comes out of this and how the race shapes up." Reynier opted to give Marianafoot a break before bringing him back in autumn for the
Prix de la Foret but the horse was withdrawn from the race owing to the unsuitable ground conditions. He failed to reproduce his six-year-old form in his next two starts as he finished sixth behind Prince Lancelot in the Prix Servanne and then ran second to Egot in the Prix du Palais-Royal. == Breeding career ==
