Running 1:00:00 [3] 12.0 km (5:00 / km)
Our hotel is in central Buenos Aires so I took the metro out about 7 stops for the start of my run which became a tour of some of the cities key outdoor sights. I started around the botanical gardens (had to run around the outside as it was still closed), the Eco parque, the Monumento de los Espanoles "Monument of the Spanish", the rose garden, the planetarium, the Japanese garden, the Floralis Generica, the National Arts Museum and finally past the entrance to Recoleta Cemetery before running back through the streets for the last 2k.
We visited the cemetery two days ago. It would make an amazing sprint map (probably at 1:2000, any larger scale you would struggle to map every passable route). You can check it out on Google Earth if you are interested.
Buenos Aires is a really beautiful city.
