Greek marathon talents Amadeus Clements and Panagiotis Petroulakis competed in the Athens Marathon wearing ENGO 2 — the lightweight, performance-focused smart glasses engineered for endurance athletes who need real-time feedback on their performance, without breaking focus.

With the smart glasses market size projected to reach USD 8.26 billion by 2030, growing at a CAGR of 27.3 percent — per Grand View Research, AI-powered smart glasses are experiencing growth driven by a convergence of technological advancements and increasing consumer demand for wearable technology that looks good and is technologically on-point. It was evident this Sunday, at the Athens Marathon, where marathon talent Amadeus Clements and Panagiotis Petroulakis raced equipped with ENGO 2 smart glasses.
After months of training among world-class runners in Iten, Kenya, Clements aimed for a top national placing using ENGO’s real-time pace, heart-rate and distance display to stay locked into race strategy without breaking visual focus. Petroulakis, current Greek 10K road race champion, integrated ENGO into his daily training for sustained pacing and minimal distraction.
These smart glasses could be a game changer for endurance athletes: be it training for a marathon or everyday runs and trails, it allows them to track statistics without looking down at a smart watch. With this real-time hands-free data stream on hand, they can adjust their intensity instantly, ensuring they stay in the desired training zone or marathon pace without breaking focus. With features like real-time performance tracking, hands-free gesture controls, automatic brightness adjustment, and simple device integration, ENGO allows both marathon athletes and everyday runners to achieve their goals with complete focus.
Why It Matters
Running is a sport built on focus, endurance, and precision. Whether an athlete is competing in a marathon or navigating a technical trail run, staying aware of their pace, heart rate, and performance data is crucial. ENGO eyewear aspires to empower the way runners train and race by bringing real-time performance data directly into their field of vision. The most important data—speed, cadence, heart rate, distance—is displayed right in front of the eyes without reaching out for a smart watch, allowing them to run smarter. This approach could empower elite athletes to manage their races, smartly and with complete focus.
“Training in Iten pushes me to raise my standards. Every session becomes a race — and every race makes me stronger. With ENGO, I can keep my head up and my pace locked in. It helps me stay in rhythm without losing focus — no more losing seconds checking the watch” says Amadeus Clements. “With ENGO, I can maintain a steady pace, making my training more effective. I use them during sessions and races to control my pace and monitor my heart rate. They provide great sun protection while seamlessly connecting with my Garmin watch. ENGO helps me go faster — with no distractions” adds Panagiotis Petroulakis.

The Age-Group Athlete Experience
Many master’s athletes in the ENGO community have experienced this challenge firsthand. Marathon runner Min Park describes on the smart glasses’ official website how ENGO transformed his Boston Marathon experience: “Seeing my pace right there in my field of view—without having to break stride to look at my watch—was amazing! I was pleasantly surprised to have averaged a pace slightly faster than my goal during this last challenging section.” For master’s athletes like Justin Fiske, the ability to see metrics clearly becomes increasingly valuable with age: “I use Engo 2 to monitor my pace, overall time elapsed, and heart rate, these are absolutely critical for any speed, threshold, tempo run or long runs! I also don’t have to look down at my watch ever!”
