Glucose management during endurance exercise is one of the most critical and least well-understood aspects of athletic performance. Glycogen depletion, commonly known as “bonking” or “hitting the wall,” occurs when muscle and liver glycogen stores are exhausted during prolonged exercise, causing dramatic performance decline. A 2023 review published in Sports Medicine by Podlogar and Wallis examined the relationship between blood glucose dynamics and endurance performance, finding that maintaining glucose availability during exercise above 2.5 hours directly influences both physical output and cognitive function, and that individual glucose kinetics during exercise vary substantially even among athletes following identical fueling protocols (DOI: 10.1007/s40279-022-01820-7).

Traditional fueling strategies rely on time-based protocols (consume X grams of carbohydrate per hour) that do not account for individual absorption rates, metabolic efficiency, or the real-time glucose dynamics that vary with exercise intensity, environmental conditions, and pre-exercise nutritional state. Supersapiens addresses this gap by providing real-time glucose data during training and competition, enabling athletes to make data-driven fueling decisions based on their actual metabolic state rather than generic protocols.

What Is Supersapiens?

Supersapiens is a glucose monitoring ecosystem designed specifically for athletes, built around Abbott’s Libre Sense Glucose Sport Biosensor. The system provides real-time glucose data through a companion app that integrates with popular athletic platforms including Garmin, Wahoo, TrainingPeaks, and Apple Health, allowing athletes to view glucose data alongside heart rate, power, pace, and other training metrics during workouts and races.

The Abbott Libre Sense biosensor is a circular patch (35mm diameter, 5mm thick) applied to the back of the upper arm. A thin, flexible filament extends just under the skin to measure interstitial fluid glucose continuously. Each sensor lasts 14 days. The biosensor was developed specifically for the sports market in collaboration between Abbott and Supersapiens.

The Supersapiens app presents glucose data in an athlete-specific framework: rather than the medical-oriented high/low alerts used by diabetes CGMs, Supersapiens shows glucose trends in the context of training zones, fueling windows, and performance optimization. Athletes can see their Glucose Performance Zone (the optimal glucose range for sustained performance) and receive real-time guidance on when to fuel during exercise.

The system has been adopted by professional cycling teams (Chris Froome is an investor), elite triathletes (Jan Frodeno), and was the title sponsor of the Ironman World Championship. Supersapiens is currently available in Austria, France, Germany, Ireland, Italy, Luxembourg, Switzerland, and the United Kingdom, with pricing starting at approximately €130 for a 28-day subscription including two biosensors.

The Science Behind Glucose-Guided Athletic Fueling

During endurance exercise, the body draws fuel from three primary sources: muscle glycogen, liver glycogen, and blood glucose (which is replenished by dietary carbohydrate intake and hepatic glucose output). As exercise duration extends beyond 60 to 90 minutes, glycogen stores progressively deplete, and maintaining blood glucose through external carbohydrate intake becomes increasingly critical for performance.

The optimal carbohydrate intake during endurance exercise has been extensively studied, with current guidelines recommending 60 to 90 grams per hour for exercise lasting longer than 2.5 hours (using glucose:fructose combinations to maximize absorption through multiple intestinal transporters). However, these are population-level recommendations that do not account for individual variation in glucose absorption rate, hepatic glucose output, insulin sensitivity during exercise, or the interaction between exercise intensity and carbohydrate oxidation rate.

Real-time glucose monitoring during exercise addresses this individual variability directly. An athlete can see their glucose declining during a hard effort and fuel before reaching critical depletion, rather than waiting for the subjective symptoms of bonking (fatigue, dizziness, confusion) that indicate glucose has already fallen below optimal levels. Conversely, an athlete can see that their glucose is stable and avoid unnecessary fueling that could cause gastrointestinal distress.

The concept of a Glucose Performance Zone acknowledges that athletic performance does not require maximum glucose levels but rather glucose stability within an optimal range. Too-high glucose can indicate excessive fueling or insulin resistance, while too-low glucose indicates inadequate fueling or excessive glycolytic demand. Maintaining glucose within the performance zone optimizes both physical output and cognitive function.

What Supersapiens Does Well

The athlete-specific data presentation transforms raw glucose data into performance-relevant information. Diabetes CGMs display glucose with medical alert thresholds (high = hyperglycemia risk, low = hypoglycemia risk). Supersapiens reframes glucose within athletic performance contexts: fueling zones, performance windows, and training adaptation metrics.

Integration with Garmin, Wahoo, TrainingPeaks, and Apple Health means glucose data appears alongside the metrics athletes already use (heart rate, power, pace), creating a unified training dashboard. Athletes can correlate glucose trends with training load, intensity, and performance in post-workout analysis.

The professional sports adoption provides both credibility and practical validation. When elite athletes at the highest levels of cycling and triathlon use a system for performance optimization, it demonstrates real-world utility beyond theoretical benefit.

The 14-day sensor wear time matches the longest-wearing consumer CGM sensors, minimizing the frequency of sensor changes and the associated cost and inconvenience.

Pricing, Access, and Practical Realities

Supersapiens pricing starts at approximately €130 ($140 to $150 USD) for a 28-day subscription including two Abbott Libre Sense biosensors. Monthly costs typically range from $150 to $200 depending on market and plan frequency.

Currently, Supersapiens is available in select European markets (Austria, France, Germany, Ireland, Italy, Luxembourg, Switzerland, and the United Kingdom). US availability has not been established, which limits access for North American athletes. The regulatory pathway for the Abbott Libre Sense Sport Biosensor in the US market may differ from Europe.

Athletes should consider that glucose data during exercise requires learning to interpret. Unlike heart rate or power, which have well-established training zone frameworks, glucose-guided training is a newer concept that requires athletes to develop an understanding of their individual glucose dynamics before the data becomes optimally actionable.

Who It Is Best For

Supersapiens is best suited for endurance athletes (cyclists, triathletes, runners, swimmers) competing or training at durations where glycogen depletion becomes a performance limiter (generally 2+ hours). Athletes who have experienced bonking, GI distress from fueling, or inconsistent race-day nutrition will find glucose-guided fueling the most immediately valuable.

Serious recreational athletes who want to optimize their fueling strategy for marathons, century rides, Ironman events, or multi-day stage events represent the core market.

The system is less suited for strength athletes, short-duration sport athletes, or casual exercisers whose performance is not significantly influenced by glucose dynamics. It is also currently inaccessible to US-based athletes due to market availability limitations.

How It Compares

Against consumer CGM programs like Veri and Levels Health, Supersapiens is purpose-built for athletic performance rather than general metabolic health. Veri and Levels focus on meal optimization and lifestyle coaching; Supersapiens focuses on real-time exercise fueling and training adaptation.

Against traditional fueling strategies (time-based carbohydrate intake), Supersapiens provides real-time data that personalizes fueling decisions to individual glucose dynamics rather than relying on population-average protocols.

Limitations and Open Questions

US market availability is the most significant limitation for North American athletes. The regulatory and commercial pathway for US launch has not been detailed publicly.

The interstitial fluid glucose measured by CGMs lags behind blood glucose by 5 to 15 minutes, which is relevant during rapidly changing exercise conditions. Athletes should interpret glucose trends (direction and rate of change) rather than relying on instantaneous values during high-intensity efforts.

The ongoing subscription cost is a significant commitment for a tool that is primarily useful during long-duration exercise sessions. Athletes who train 5 to 10+ hours per week may find the cost per actionable insight reasonable; casual exercisers may not.

What This Means for Your Health

Glucose management during exercise represents an intersection of the Movement and Nutrition pillars within Healthcare Discovery‘s Five Pillars framework. Optimizing fueling strategy through real-time glucose data not only improves acute exercise performance but may support better long-term metabolic health by preventing the extreme glucose fluctuations and subsequent counter-regulatory hormone responses associated with poor exercise fueling.

The personalization enabled by continuous glucose monitoring during exercise aligns with the broader precision medicine movement: individual physiology varies too much for one-size-fits-all protocols to optimize outcomes for every person.
