"As a middle-distance runner specializing in the 800m, every fraction of a second counts. During my training, I used ENGO to fine-tune my running dynamics—adjusting my stride length, foot placement, and posture. Having that real-time feedback helped me understand how even small tweaks could boost my efficiency. I applied those insights in competition, and when I hit a 2'04'27, it felt like all the hard work had finally clicked. That performance qualified me for the French Nationals, and ENGO played a huge part in helping me get there.

The 800m is a unique hybrid distance requiring both explosive speed and aerobic efficiency. We operate constantly on a razor's edge where the slightest inefficiency—a moment of tension, an unnecessary movement, a pace miscalculation—can cost precious seconds. This is precisely where ENGO has transformed my training approach.

For nearly two years, I've integrated ENGO eyewear into my threshold sessions and fartlek workouts. The ability to monitor my pace and heart rate without disrupting my stride has added a new dimension of precision to these crucial sessions. When my coach prescribes specific intensity zones, I can maintain them with perfect accuracy without the energy-draining gesture of checking my watch.

What might seem like a minor detail—eliminating the need to glance at my wrist—actually represents significant energy conservation over the course of a demanding session. At the elite level where margins are infinitesimal, this efficiency can be the difference between hitting a training target and falling short.

The French athletic system emphasizes precision in preparation, and ENGO aligns perfectly with this philosophy. As I work toward making my mark at the senior level, having this technology as part of my daily training provides both physical and psychological advantages. The confidence of knowing exactly where I stand at any moment during a session allows me to focus entirely on execution rather than data collection.

Pour les athlètes qui cherchent à optimiser chaque détail de leur entraînement, je considère qu'ENGO est un outil indispensable qui apporte un véritable confort et une précision remarquable à la préparation quotidienne."
