Prix du Jockey Club
Tanerko began his racing career by winning the Prix Juigné, a contest for previously unraced three-year-olds over 2100 metres at Longchamp Racecourse. He then recorded wins in two of the major trial races for the Prix du Jockey Club, taking the Prix Noailles over 2200 metres in late April and the Prix Lupin over 2100 metres in May. He was then moved up in distance for the Prix du Jockey Club over 2400 metres at Chantilly Racecourse in June and finished third behind Marcel Boussac's Philius who won by two lengths from Saint Raphael.
