"Running a marathon is as much a mental challenge as it is a physical one. Every competitive runner faces a frustrating dilemma: wearing a watch creates background stress. Either you're distracted by checking it constantly, or you're anxious about missing a potential performance drift. This mental tug-of-war disrupts your running economy and prevents you from reaching that ideal flow state.

At the LA Marathon, where I ran a 2h57'35", ENGO was a game-changer. With real-time metrics in my line of sight, I eliminated the need for watch-checking entirely. I could relax, focus on my stride, and let my body do what it's trained to do.

The data anxiety that haunts every competitive runner simply vanished. Before ENGO, I'd feel that familiar spike of stress every time I needed to check my watch—worried about what I might see, breaking stride to glance down, then overthinking the numbers. That constant mental calculation—'Am I on pace? Should I push harder? Am I burning out too early?'—was exhausting and counterproductive.

With ENGO, those metrics became a reassuring presence rather than a source of stress. The constant metrics awareness created a sense of calm and control that allowed my mind and body to align for optimal performance. I could process the information passively, making micro-adjustments without the psychological burden that comes from the cycle of wondering, checking, and worrying.

The background anxiety that plagues every marathon runner? Gone. I felt completely in control for the entire race, maintaining my running economy while staying perfectly aware of my pace and splits. This mental clarity translated directly into physical efficiency—no more tension from uncertainty, no more disrupted breathing patterns from checking my watch.

ENGO didn't just change how I accessed my data—it transformed my relationship with it, turning what was once a source of stress into a foundation for confidence. That peace of mind is something every runner seeks but rarely finds, and it made all the difference in achieving my marathon goal."
