hi kimeth!
In Parque Centenario (a rounded place, almost middle Cap Fed) you have one of.... 1500mt, I think... marked by 200mt or some... it actually the border of the park, also if you are near San Telmo o el centro, you can do Reserva ecologica, it nice to run not marked, but they have maps with distances.
