Trimarni Coaching and Nutrition

There has been substantial talk surrounding RED-S and for good reason.  Adequate energy intake is essential for athletic performance, recovery, and long-term health.  Yet many athletes, across all sports and competitive levels, fail to meet their daily energy needs.  A chronic mismatch between energy intake and energy expenditure can lead to low energy availability, impairing performance and increasing the risk of injury, illness, and hormonal disruption.  Although RED-S is often viewed as the result of intentional undereating (when athletes consciously restrict food intake due to performance beliefs, body image concerns, or external pressures) undereating can also occur unintentionally.  Framing RED-S solely as a consequence of deliberate restriction or disordered eating overlooks a substantial subset of athletes who fail to meet their energy needs due to factors such as high training volume, appetite suppression following intense exercise, time constraints, l...

Within 7 days, Greenville has experienced an ice storm and a snow storm. Needless to say, we've been doing a lot of our training indoors over the past week.    Indoor training, whether it's running on the treadmill or riding on the trainer, is common for most endurance athletes. It’s efficient, controlled, and time‑effective. But when it comes to supporting those sessions with proper fuel and hydration, this is where many athletes struggle to get things right.  Some athletes intentionally underfuel, assuming that indoor sessions “don’t count” as much as outdoor workouts. Or athletes feel safe cutting calories because there's no risk in running out of fuel - you just stop and you are home. Others, however overfuel, grazing out of boredom or because nutrition is sitting on a table within arm’s reach. The sweet spot lies in fueling intentionally.  Why Indoor Workouts Change Your Fueling Needs Indoor training is different from outdoor training in a few key ways: Steadier...

Lately, my heart has been heavy. I watch what’s happening in the United States—the rhetoric from our leaders, the actions of ICE, the open hostility toward immigrants—and I feel a deep sadness. Not just because it’s cruel, but because it betrays what America is supposed to be. I was born in the United States and for my first 24 years, I always felt like I belonged here. My idea of what it meant to be an American changed a few years after meeting Karel - my now husband of almost 18 years. Karel came to the United States from the Czech Republic with nothing but a backpack and a belief in the American Dream . He grew up under communism, where freedom was limited and opportunity was rationed. Like so many before him, he came here not to take, but to build a life through hard work and sacrifice. When Karel arrived in the U.S. he overstayed his visa and became an illegal immigrant. What many people don’t understand is that “illegal” does not make someone a criminal or threat to society. It...

For decades, Americans have been introduced to food guides—the pyramid, the plate, and multiple types of visuals meant to simplify nutrition. Each new version promises clarity about what we (Americans) should eat. Yet despite these evolving guides, rates of diet-related disease, obesity, health issues, and frustration around eating continue to rise. In my opinion, the problem isn’t the lack of information about what to eat. The problem is that Americans don't know how to eat.  As an example, people in the Blue Zones and in many other parts of the world live long, healthy, and meaningful lives not because they follow extreme diets, but because their eating habits are simple, consistent, and deeply ingrained into daily life. Their diets are mostly plant-based, with an emphasis on whole grains, healthy fats, and foods for enjoyment—often shared with family and community. Meals are regular, unrushed, and social, and food is viewed as nourishment and connection rather than control. Thi...

  The 2025 season provided us with a great reminder that success in endurance sports isn’t defined by a single finish line, but it's built through consistency, curiosity, and the courage to step outside of what feels comfortable. At Trimarni, we specialize in endurance sports, with triathlon at the core of what we do. What sets our athletes apart is their willingness to explore beyond traditional boundaries. This year, our team showed up across a wide range of events: off-road triathlons, cycling races, open water swims, road and trail running races, and sprint and Olympic-distance triathlons. Each start line allowed for growth, adaptability, and a commitment to becoming more complete athletes. While long distance triathlon success is created from consistency, endurance athletes thrive off adaptability. Racing across disciplines and formats offers benefits that "long" training sessions alone can’t replicate. Off-road triathlons and trail runs build strength, resilience, a...
