Blek proved the clear victor of the Prix Maurice De Nieuil at Longchamp under the guidance of Yohann Bourgois, giving trainer Elie Lellouche his fourth triumph in the event.
British concern in the event waned when, because of the heavy rain that had deluged the track over the day making the course very soft, Purple Moon was declared a non-starter.
Six starters remained in the running, with the German mount Titurel being the first to head out and proceed to lead the field at a even pace up to rounding the last turn.
Other than the victor, none of the challengers ever got into an actual contest, including Frankie Dettori on Roatan, and with more than a furlong to go, Blek was able to charge away.
Los Criastanos ran Titurel out of second inside the final furlong.
Winning trainer Lellouche said,"He really accelerated today and we are so happy it rained. We will now have to look at a Group 1 event so the Prix du Cadran will probably be his autumn target. There is also a possibility that he could run in the Prix Kergolay at Deauville if there is cut in the ground."
Owner Alain Maubert stated, "I was watching the Bastille Day parade at the Champs Elysees when itbegan to rain and then we knew luck was going our way. I was surprised how easily he won today. I think I paid something like â‚¬35,000 when I decided to keep the horse after he won a claimer. Mr Lellouche suggested we put Yohann Bourgois in the saddle and I was delighted Blek gave him his first Group success."
