Dominique Boeuf took over the ride when the colt was moved up in class and distance for the Group One Critérium de Saint-Cloud over 2000 metres on 29 October.
Restrained at the back of the five-runner field he made strong progress in the straight but failed by a short-head to catch Polaris Flight.
Khalid Abdullah's colt Radevore started favourite, whilst the other runners included Oliviero (third to Helissio in the Prix Noailles).
"[7] On 2 June Ragmar contested the 159th running of the Prix du Jockey Club over 2400 metres on firm ground at Chantilly Racecourse.
He took the lead 200 metres from the finish and held on to win by a nose and a short neck from Polaris Flight and Le Destin with Helissio in fifth.

At the end of his racing career, Ragmar became a breeding stallion, standing at the Haras de Saint-Gatien before being bought by the French National Stud.
