Facing 9 other combinations in the tiebreaker, out of the 45 other pairs that contested the first-round course designed by Grégory Bodo (FRA), Bosty was supreme aboard the 2013 bay Selle Français stallion (Air Jordan x Tlaloc M), clearing all the 1.55m obstacles effortlessly before securing the fastest time in 41.47 seconds.

Robert Whitaker (GBR) and Vermento earned silver honors, finishing only thirteen hundredths of a second behind the eventual winners.

Julien Épaillard (FRA) and Donatello d’Auge (Jarnac x Pierreville) came close too, but one rail down along the way made the flying frenchman take his foot off the pedal, still earning bronze honors in 41.85 seconds.
