THE DISRUPTER

As the CEO of Rivian, the first manufacturer of off-road EVs, RJ Scaringe blazes up and down trails to rev his cardio and clear his mind.

"SEND IT!" whoops RJ Scaringe before pointing his mountain bike down a swath of single track that descends steeply through a redwood forest in northern California's El Corte de Madera Creek Preserve. His tone is joking, but as he bombs over roots and rocks, he looks focused-not surprising, seeing as he recently completed 12 weeks of post-surgery rehab for a torn labrum, thanks to a mountain-bike accident last year.

"I'm a fan of mountain biking, because I love being out in nature," he says. "You get the adrenaline rush of going fast downhill and the cardio challenge of riding uphill."

In high school in Florida, Scaringe played basketball and was "super competitive," he says. At 41, the CEO of Rivian, the EV company that makes adventure-ready SUVs and trucks (and Amazon's e-delivery vans), now relies on mountain biking, as well as mellow hikes and burly surf sessions, to create balance in his body, mind, and pedal-to-the-metal life. "For me, exercise is about finding a way to feel comprehensively healthy," he says. "It helps me think clearly, de-stress, and make better decisions. It puts me in the right headspace to handle all the demands of my job."
