The 1911 Tour de France was the ninth edition of the Tour de France, taking place from 2 to 30 July. It was composed of 15 stages over 5,343 kilometres (3,320 mi), ridden at an average speed of 27.322 km/h. The results were computed by giving each rider points according to his finishing position on each stage, and the rider with the fewest points at the end of the race won the overall competition. It was a gruelling tour, with the longest stage, 470 km long, taking almost 18 hours for the fastest riders to complete. Out of the 84 riders who started the tour, only 28 completed the race. After the introduction of the Pyrenees in the previous edition, in 1911 the Alps were first visited; for this addition, the 1911 edition has been named the first modern Tour.

Cyprien Gustave Garrigou was one of the best professional racing cyclists of his era. He rode the Tour de France eight times and won once. Of 117 stages, he won eight, came in the top ten 96 times and finished 65 times in the first five.
