The larger race areas provide more flexibility, and their location has fewer geographical boundaries, so there will be more variety in the course configuration outside.
Besides coastal flow, Page says, the current is no different from any other continental coast. “You’ll get up to a knot of current,” he says. “Compared to the breeze, it’s a minor factor.”
Rio’s sea breeze generally fills at 1 p.m. In the Southern Hemisphere winter during the Games, sunset will be around 5 p.m., creating a narrow racing window. “Having so many courses gives us flexibility with pollution, but also, and more importantly, [there are more racecourses] because of the weather,” says Page. “The variables are stronger in Rio than in many other places on the globe. We have to be conscious of it.” — Lisa Gabrielson
