Justin Riele is a professional triathlete who races at the highest level while balancing a full-time role as Senior Director of Marketing at Upstart, a tech company. Born and raised in San Francisco, California, he now lives in Las Vegas, Nevada with his wife, Lauren.

Justin studied Neuroscience at Vanderbilt University, where he spent much of his time with his fraternity and performing in The Melodores, the university’s a cappella group that won Season 5 of NBC’s The Sing-Off.

He discovered triathlon at age 23 and has since achieved more than he ever imagined possible. After winning his age group at the 2021 Ironman World Championship, Justin earned his professional license and hasn’t looked back. He views his racing career as an ongoing experiment—proving that an amateur with a full-time corporate job can rise through the pro ranks and compete on the world stage.

Justin is coached by Lauren Goss of Blacksheep Endurance.

"I'm enjoying every minute of racing as a professional, and I feel incredibly blessed to be able to compete on the world stage."
