It was organized by the Pyrenees Committee (Comitè des Pyrénées), which was one of the regional bodies of the USFSA (the predecessor of the French Football Federation), in charge of the competitions in the south of France.
In 1909, given the success that the northern competition had achieved, and despite the fact that the French Championship organized by the USFSA had gradually been extended to all the clubs in the country, an Occitan patron (Monsieur Labat) from the Committee of the Pyrenees of the USFSA had the initiative to carry out a similar competition in the south of France, extended to some Spanish clubs, and thus the Challenge International du Sud de la France was born.
While Sociedad trashed toulousain with a resounding 8–0 win, Barça drew with Olympique at 1, so extra-time was to be played, but Olympique refused to do so claiming tiredness; so Barcelona qualified to the final where they beat Sociedad 2–1 thanks to first-half goals from Ricard Graells and Pepe Rodríguez,[4][5] the latter having just landed in FC Barcelona with barely no time to meet his teammates, but despite that he still managed to score a title-winning goal on his debut.
[7] In the semi-finals FC Barcelona beat Olympique de Cette again, this time 2–1, courtesy of a brace from Carles Comamala, who also scored once in the final against Stade Bordelais to help his side with a 4–2, with the remaining Barça goals coming from the Wallace brothers, Charles and Percival (2).
The third edition was contested by 9 teams and saw FC Barcelona having to start from the quarter-finals for the first time, beating RCD Espanyol 3–2, thanks to goals from their Scottish forwards George Pattullo (2) and Alexander Steel.
Interestingly, none of them had to play the semi-final as both their opponents Forfeited for different reasons: Club Nîmes could not find enough players to make the trip, while Real Sociedad were unwilling to pay for the cost of transportation.
The first treble of the Pyrenees Cup was scored by Mariano Lacort on 17 April 1910 in the inaugural edition of the competition, netting four goals to help Real Sociedad beat Stade toulousain 8–0.
[4] It's worth mentioning that this was the only time Lacort found the back of the net in the Pyrenees Cup, but despite that his 4-goal haul alone makes him one of the all-time top goal scorers in the competition's history.
