Jorgensen's sport is among the most grueling on the planet, covering swimming (.93 miles), running (6.2 miles), and cycling (24.9 miles). To perfect her form, her trainers brought in virtual-reality pioneer Joe Chen. He is a former product lead at Oculus, and now at Vrse.works, the production house that makes VR movies and VR content for big media companies. Chen flew to Brazil and attached a bunch of GoPros to the hood of a car, matching it to the eye height of a cyclist. “Then we just drove the course,” capturing it in 360 degrees, he says. He then converted the entire thing to an MPEG viewable on a Samsung Gear VR headset. Jorgensen now uses it to follow the entire bike route, or to play short clips of isolated sections that she can study in detail. In other words, Rio came to her.
