Chuck Knuth

Growing up, Coach Chuck had an intense fear of water that prevented him from swimming in deep water. At 15, he flipped an old 10-speed bike and knocked out a few of his teeth. Clearly, he was destined to become a triathlete.

Despite that oh-so-promising start, he is today an athlete, a fan, and a mentor who is obsessed with this sport. His tally (which is probably already outdated) includes 13 full Ironmans, nine 70.3s, countless olympic- and sprint-distance races, and no fewer than 20 half and full marathons. To top it all off, in 2024, he is lucky enough to race in the Ironman World Championships in Kailua-Kona, Hawaii.

As a coach, every athlete comes with a new puzzle. You and Coach Chuck will work together to create the approach that works best for you and gets you to your goal. Not every workout can be a home run, but at the same time, not all bad ones are strikeouts. He’ll be your loudest cheerleader and the person who pushes you to challenge yourself, but he’s also the first to be realistic about the process.

When he’s not training or racing, you’ll find him traveling with his wife, Amanda; relaxing at home with their dog; rebuilding and tinkering on cars; or working toward his next big goal: getting his pilot’s license.
