The Afasteryou Story
From a simple question in 2016 to the most advanced training platform today
The Beginning: Aero for Everyone
It all started with one powerful question: Why should aerodynamic performance analysis be reserved for professionals? Back then still known as Aerotune, we had an ambitious vision: Bring CdA testing out of the wind tunnel and onto the open road — affordable, accessible, and accurate.
Velodrome Precision
The Aerotest Velodrome Protocol was developed: controlled conditions, repeatable laps, and significantly improved accuracy. This marked the shift from an engineering experiment to a reliable diagnostic tool used by professional teams, WorldTour teams, national squads, coaches, and ambitious athletes — especially in high-stakes time trial and track environments.
The aeroAPP: Becoming a Platform
With major upgrades to the aeroAPP, we transitioned from single test moments to a true performance platform. Athletes could store and compare setups, track aerodynamic progress over time, and — most importantly — follow a guided, step-by-step workflow that makes testing reliable and repeatable.
Aerodynamics became part of everyday training — not a once-a-season luxury.
Powertest: Lab-Quality for Everyone
The Powertest was our biggest leap: delivering VO₂max, VLamax, and metabolic insights at lab level — without the lab. We developed multiple protocols, physiology-driven modeling, and a simple workflow that stays reproducible across environments.
Today it supports development across professional teams, WorldTour teams, national squads, and dedicated age-group athletes, and it has contributed to successful performance planning at top international competitions.
Race Simulation & Metabolic Scenarios
With Powertest data, we built a race simulation engine that combines metabolic modeling, aerodynamics, physics, terrain, and environment — enabling athletes and teams to test pacing strategies and quantify time savings.
In parallel, we expanded Powertest analytics to cover different metabolic scenarios, including carbohydrate demand and usage across intensities, helping athletes plan fueling and training with far more precision.
This also marked the beginning of training our Activity Analysis — learning how real athletes respond to training stress across weeks and months.
Powertest & Synthetic Data Patent
A turning point: we enabled weekly estimation of VO₂max and VLamax from regular training rides — reducing the need for frequent dedicated tests and allowing continuous trend monitoring.
European Patent Granted
Our synthetic data generation method for machine learning training was granted a European patent, proving we don't just use standard algorithms — we build original innovations.
View PatentEnd of 2023, we became Official Supplier for Team Visma | Lease a Bike. In addition, many WorldTour teams continued to use our ecosystem for testing, modeling, and performance planning.
Simulation Accuracy & Training Intelligence
Our race simulation matured into a highly accurate decision tool, used by WorldTour teams to prepare key time trials and pacing strategies.
At the same time, our training system improved substantially: better interpretation of daily sessions, clearer readiness signals, and an expanded physiological backbone — including an integrated lactate model.
We also continued to refine aero workflows, including velodrome and outdoor protocols, making testing more consistent and actionable.
Afasteryou & TrainingPlan: Athlete-Specific Intelligence
In 2025, Aerotune evolved into Afasteryou — reflecting our mission more clearly: turning science into measurable improvement for every athlete.
Our most ambitious innovation is the TrainingPlan, built on each athlete's complete metabolic profile (VO₂max, VLamax, thresholds, substrate use) and real-world training outcomes gathered over years.
What makes it different:
Unlike generic chat systems, this is not based on a large language model. It is a specialized, data-trained model designed for performance planning — learning from training history, Powertest insights, and individual response patterns to guide fully automated, day-to-day decision making.

Hans Becking
Dutch Professional Mountain Biker
After illness, Hans came back to win the 4 Islands Stage Race with close support from our Training AI. Continuous tracking of fitness and performance values brought him back to peak form in just three months.
Trusted by Professional Teams
Including UCI World Tour teams for velodrome testing and aerodynamics optimization
"I use Training AI for long-term development tracking of my athletes. It allows me to monitor how fitness progresses over months, especially VO₂max, VLamax, and glycolytic power. Plus, I can analyze daily trainings and races more precisely: how taxing they were metabolically, how much energy they cost, and how they impact performance readiness."
