I will present the measurement of the cosmic distance scale from the detections of the baryon acoustic oscillations in the clustering of galaxies from the Baryon Oscillation Spectroscopic Survey (BOSS), which is part of the Sloan Digital Sky Survey III (SDSS-III). Our results come from the Data Release 11 (DR11) sample, containing nearly one million galaxies and covering approximately 8 500 square degrees and the redshift range 0.2 < z < 0.7. I will also discuss how errors have been determined by means of galaxy mock catalogues.
