In searching for yesterday’s track, I happened to see Estádio do Morumbi. It caught my eye because of the colorful interior, and the waves of color surrounding the track. Upon a closer look (via Google Streetview which is available inside) this is an interesting facility. The color waves appear to be colored gravel, with the green being grass. The track itself only has four full lanes, but four more are added to the main straightaway on the west side. Access to the infield is gained by using the three tunnels you see on the north end. Field events seem to be pretty limited here.
This stadium has a long history, when construction began in 1952. It opened in 1960, and has undergone numerous renovations over the years. At one point (in 1970) the capacity was 140,000. It has since been reduced and now currently seats 67,052, but is still the largest privately owned stadium in Brazil. It was supposed to be one of the sites for soccer for the 2016 Summer Olympics, but that has now changed. While it may not be the best track & field facility, visually it looks stunning.
You can view an extensive photo gallery of the stadium HERE.
