For years, endurance athletes have measured performance through two primary metrics: power output and heart rate. These numbers have dictated training intensity, race pacing, and overall efficiency. But as technology advances, a new, critical metric is emerging—aero data. In the pursuit of speed and efficiency, aerodynamic optimization is no longer just for elite professionals; it’s becoming a must-have performance metric for all cyclists and triathletes.
Why Aerodynamics Matter More Than Ever
In endurance racing, speed is dictated not just by how much power you produce but how efficiently you convert that power into forward motion. Aerodynamic drag accounts for up to 90% of resistance at high speeds in cycling and triathlon. Even small reductions in drag can lead to massive time savings, allowing athletes to ride faster without increasing effort.
Traditional training metrics like wattage and heart rate provide insight into effort and endurance, but they don’t tell the full story. Two athletes could be riding at the same power output, but if one has superior aerodynamics, they’ll be significantly faster while expending the same energy. This is why aero data is the next evolution in performance tracking—and why more professionals are making it a priority.

How Darefore is Revolutionizing Aero Tracking
Darefore is at the forefront of this shift, providing real-time aero tracking technology that allows athletes to measure, adjust, and optimize their riding position and efficiency like never before.
- Live Aero Feedback: Darefore’s sensor system captures real-time aerodynamic data, helping athletes understand when they’re most efficient and where they’re losing speed.
- Power-to-Speed Optimization: By correlating power output with real-world speed and positional stability, Darefore shows exactly how much of your effort is being wasted due to poor aerodynamics.
- Real-World Position Monitoring: Unlike traditional wind tunnel testing, Darefore gives insights during actual training rides and races, allowing athletes to fine-tune their position in real-world conditions.
- Post-Ride Aero Analysis: Darefore’s hub collects detailed session analytics, highlighting trends and identifying areas for improvement over time.

Why More Pros Are Turning to Aero Data
The rise of aero-focused performance tracking is being driven by some of the fastest athletes in the world. From pro triathletes racing Ironman to top-level time trialists in cycling, the adoption of real-time aerodynamic feedback is leading to major competitive advantages.
- Time Savings Without More Effort: Even a small reduction in drag can translate into minutes saved over an Ironman-distance bike leg.
- Pacing and Energy Conservation: By knowing exactly how much energy is required to maintain certain speeds in aero, athletes can optimize pacing and avoid unnecessary fatigue.
- Position Consistency in Training and Racing: Aero efficiency is about more than just a perfect bike fit—it’s about sustaining that position throughout a race. Darefore’s live tracking ensures that athletes stay in their most efficient position for as long as possible.

The Future of Performance Metrics
As cycling and triathlon continue to evolve, aero data is set to become as fundamental as power and heart rate. Training plans will incorporate aero efficiency drills, races will be analyzed not just by wattage but by aero consistency, and athletes will optimize their gear and positions with real-world data-driven precision.
With Darefore leading the charge in real-time aero tracking, the future of performance tracking is already here. Athletes who adopt these new technologies will gain the biggest advantage—riding faster, more efficiently, and with greater control over their performance than ever before.
