Anyway, having gotten the usual warning of not exercising outside in this country, and Johannesburg in particular, I did some search on the Internet about running in Sandton. I didn't find much, just a few posts reassuring foreigners that Sandton is particularly safe in the early morning, and recommending to run in the nearby parks or the indoor track of the Radisson Hotel's Planet Platinum gym. This didn't seem very appealing for a long run so I de zoomed on the map and found a very interesting stretch of green area along a creek, on the West side. It seemed so obvious, I was disappointed when the Concierge of the hotel had no idea about what I was pointing him to on the map. His only reaction was that it must be very far. Indeed, 4 kilometers, phew! ;-)
the Google trace of my targeted route (only to find out upon my return that I hadn't hit the send button before leaving, oops!). The sidewalks are quite uneven along the main arteries of Sandton and it's also dangerous to cross roads and streets in a country which drives on the other side of the road (I almost missed to cross one looking at the wrong side of the incoming traffic, with the wrong habit and reflex); as a result, I was glad to find the Braamfontein Spruit Trail. It's kind of the Parisian Coulée Verte (see 2007 and 2014 posts), or maybe a local PG&E trail since the trail isn't much about leveraging the nice creek as it seems to rather be to allow for the passage of a huge power line across the city.
I saw dozens of mountain bikers but only a handful of runners.
