Anyone else noticed how many horses are going left in the closing stages since the track was renovated. Cockney Rebel, the winner of the last yesterday, the Chesham winner, Red Clubs in the Diadem, Anna Pavlova in a fillies listed race last year are just a few off the top off my head. Almost certainly to do with moving the entrance to the course from the parade ring.
I’m sure you are correct on this DJ. A lot of horses seem to remember where the exit is and set a course for it rather than running straight. Towcester and Fontwell are two courses where this happens regularly also.
