Veteran trainer O’Brien considers Constitution River a strong contender for a third Prix du Jockey Club win on May 31 at Chantilly [1, 2]. The field includes 11 starters showing varied but impressive form leading into the 2100-meter race.

Dolmalan remains unbeaten this season after winning all three starts, including a Listed 2000m event at Chantilly in late April [1, 2]. Hawk Mountain has also secured four straight victories, highlighted by a Group 3 win over 1800m at Chantilly [1, 2].

German-trained Gostam claimed a Group 2 2000m race in Munich in early May and will make an international challenge [1, 2]. Alam continues to improve after a recent Group 3 win over 2100m at Saint-Cloud [1, 2].

Daryzan, half-brother to Arc winner Daryz, was favourite when winning a 1600m newcomers race at Saint-Cloud in May, outpacing 13 rivals [1, 2]. Hankelow finished a close third in a Group 1 French Classic over 1600m at ParisLongchamp in May but prefers softer ground [1, 2].

Segall narrowly won a Group 3 1800m race at ParisLongchamp in April but then failed to impact in the following Group 1 Classic [1, 2]. Oxagon, an April winner of a Group 3 1600m race at Newmarket, was supplemented for the French Derby but showed no impact in May’s Group 1 Classic at Newmarket [1, 2].

Komorebi placed second in a Group 1 Classic at ParisLongchamp over 1600m; if he handles the longer 2100m distance, he could contend [1, 2]. Campacite, from a stable with six previous Prix du Jockey Club wins, appears a surprise candidate this year [1, 2].

Gusto posted good performances this season, including a close third in a Group 3 1800m race at ParisLongchamp [1, 2]. The variety of distance preferences and recent form sets the stage for a competitive contest.

The Prix du Jockey Club is scheduled for May 31, drawing together this strong field of 11 starters, each with recent notable achievements that will shape the race outcome [1, 2].
