Trail Running

"My 2025 trail season starts soon with the World Championships on the horizon! After my European Championship victory last year, I'm laser-focused on defending my world title, and the ENGO glasses with the new heart rate zone tracking are proving instrumental in optimizing my preparation.

The team invited me to their office in Grenoble to test this new feature. As someone who transitioned from kayaking to trail running during my studies at the Institute of Political Studies, I've always valued precision, but the constant watch-checking disrupted my running economy and mental focus.

Thanks to the heart rate zone gauge, I can naturally adjust my pace and maintain a fluid stride without breaking form. During my flat-terrain sessions, I can see in real-time if I'm pushing too hard or not enough, which helps me manage my intervals and recovery with the precision I need at the world-class level. This little widget accompanies me during my threshold sessions to easily stay in the target zone without having to look at my watch, allowing me to focus purely on my technique and breathing.

After overcoming my rectus femoris injury earlier in my career, monitoring my exertion levels has become even more critical to prevent setbacks. ENGO has transformed how I approach my training, giving me the confidence to push my limits while maintaining the flow state that's essential for peak performance in technical mountain terrain.

I recognize game-changing technology when I see it. I encourage you to try it out and experience the mental clarity and performance benefits for yourself!"

 

Everything runners ask, answered.

Will I even notice a difference?
