answer:If it’s a horse you or a friend own, I’d say south down past Funston Beach. That’s where I would run mine, but he was at the stables near there in Daly City. Rental-wise, I don’t think many places will let you gallop. Either it’s liability or overworked horses. I have had some horses in Half Moon Bay take off back home at a gallop, but certainly not on purpose, ha.
