Sinndar was prepared for the Prix de l'Arc de Triomphe with a run in the Prix Niel over the same course and distance in September. The Niel often attracts the best colts in France (Montjeu and Hurricane Run were among the recent previous winners), but the opposition to Sinndar in the 2000 race was relatively weak. After taking over from his pacemaker Raypour at the start of the straight Sinndar pulled clear and beat Crimson Quest by eight lengths. Oxx was "very happy" with the performance, whilst being realistic about the quality of the opposition.
