hDrop Announces Partnership with Matt Hanson to Advance Real-Time Sweat and Sodium Monitoring in Professional Triathlon
On February 12, 2026, we announced something that represents a meaningful step forward for us at hDrop.
We are partnering with Matt Hanson, one of the leading competitors on the IRONMAN Pro Series circuit, to bring real-time sweat rate and sodium loss monitoring into elite long-course triathlon training and racing.
This partnership is not about marketing optics. It is about physiological precision.
Why We Care About Hydration Accuracy
In long-course triathlon, hydration strategy remains one of the most variable and least precisely quantified factors influencing performance. Most athletes still rely on:
- Single-session sweat tests
- General sodium replacement charts
- Environmental assumptions
- Post-session body mass comparisons
The problem is that sweat rate and sodium loss are not static. They fluctuate with intensity, heat stress, fatigue, acclimation state, and training phase. Static hydration plans cannot capture this dynamic physiology.
We built hDrop Gen 2 to continuously estimate sweat rate and sodium loss during live exercise. Our objective is simple: reduce uncertainty in hydration planning by quantifying variability in real time.
Independent Laboratory Validation
Under controlled 1-hour dynamic exercise protocols, independent testing conducted by a U.S. academic research institution demonstrated:
- 92 percent agreement with reference methods for total sweat loss estimation
- 87 percent agreement for sodium loss estimation
This validation was conducted fully independently under standardized laboratory conditions. Detailed methodology, including testing conditions and statistical analysis, will be disclosed in a forthcoming independent scientific publication.
As wearable hydration technologies expand within endurance sport, methodological rigor and third-party validation are essential. We prioritize reproducibility and transparency in our development roadmap.

Why Matt Hanson
Our collaboration with Matt Hanson is unique because he brings more than elite performance credentials. Before becoming a full-time professional triathlete, Matt served as a university professor in exercise physiology.
That background matters.
His formal training in human performance science, metabolic adaptation, and endurance physiology provides a structured framework for interpreting hydration data beyond surface metrics. Instead of viewing sweat and sodium values as isolated numbers, we evaluate them within physiological mechanisms and training context.
From Data Collection to Hypothesis-Driven Training
This partnership allows us to move beyond post-session insights.
Working within structured training blocks, heat adaptation sessions, and race preparation cycles, we are integrating real-time sweat rate and sodium loss data into hypothesis-driven training adjustments. Together, we are examining:
- Variability across environmental conditions
- Sodium replacement precision during prolonged efforts
- Cardiovascular stability under thermal stress
- Performance sustainability across race duration
Our goal is not simply to measure hydration. It is to refine individualized sodium replacement strategies and quantify how hydration precision affects endurance performance.
Bridging Laboratory Validation and Elite Field Performance
For us, this partnership represents a bridge between independent laboratory validation and real-world application at the highest level of endurance sport.
When we combine elite racing with formal exercise physiology expertise, we create a feedback loop between theory and practice. That loop strengthens both product development and applied performance strategy.
As wearable hydration technology evolves, credibility will depend on reproducibility, transparency, and physiological grounding. That is the standard we are committed to meeting.
We look forward to sharing what we learn as this collaboration progresses.
