The standard cosmological model based on dark energy, standard gravity, and cold dark matter as the driver for structure formation has passed important observational tests related to the present distribution of matter on large scales (larger than a few 10s of Megaparsecs). It will be argued that  deviations from the standard model can be further probed through signatures of the large scale motions (deviations from pure Hubble flow) of galaxies. Some constraints on f(R) and DGP gravity will be described using motions of galaxies in the nearby Universe. It will be shown how future surveys of ~ a billion galaxies  like Euclid will allow constraints on dark energy models.
