We have measured the speed of muon neutrinos with the Borexino detector using short-bunch CNGS beams. The final result for the difference in time-of-flight between an E = 17 GeV muon neutrino and a particle moving at the speed of light in vacuum is δt = 0.8 ± 0.7stat ± 2.9sys ns, well consistent with zero.
