Introducing FLOWBIO: The Game-Changer in Preventing Dehydration

What if the most important performance metric you’re missing is sweat?

Hydration advice is everywhere in endurance sport. “Drink before you're thirsty.” “Add electrolytes.” “Take care in the heat” These are decent rules-of-thumb, but leave a hell of a lot of room for guesswork.

Because here’s the reality: your sweat losses are personal, and if you're not tracking them, you're hydrating in the dark.

You’ve Normalised the Warning Signs

Cramping mid-session. Hitting the wall in the final third of your race. Inexplicable dips in performance from one day to the next.

Too often, we chalk it up to undertraining, bad luck, or poor fuelling. But in many cases, it’s a hydration issue; specifically: an imbalance in sodium and fluid that’s gone unnoticed.

Despite how much we track pace, power and heart rate, sweat remains the blind spot in most training setups.

Generic Hydration Plans & Sweat Tests Don’t Cut It

“Drink X litres per hour.”
“Take Y mg of sodium every 30 minutes.”

These are average recommendations, and they assume everyone sweats the same. And everyone’s sweat rates stay constant. But that’s simply not the case.

Take a 60 minute steady run session. Some athletes will lose 400mg of sodium on a hot day. Others lose over 2,000mg at brisk temperatures. Sweat rate and sodium loss response vary widely between people and significantly change based on weather, intensity, duration.

A plan that works for someone else could be holding you back.

FLOWBIO: Real-Time Sweat Intelligence

FLOWBIO changes the game by putting lab-level hydration insights directly into your training sessions. The FLOWBIO Sensor measures:

• Sweat rate
• Sodium loss
• Skin temperature

All in real-time, during your actual workouts, no test patches, no lab visits.

As you use the sensor, the app uses this data to build your personal predictive model, giving you a clear hydration strategy that adapts to the session, not just the season.

What You’ll Learn from FLOWBIO

With FLOWBIO, you can:

• See exactly how much fluid you're losing
• Know how much sodium you need to replace
• Adjust for heat, humidity, and intensity
• Plan pre, during, and post-session hydration with precision
  

It’s not about drinking more, it’s about drinking smarter.

High-Performance Insight, Every Session

What used to take a lab and a white coat is now wearable, accessible, and seamlessly integrated with your kit. FLOWBIO pairs with Garmin, Wahoo, Zwift, Coros and more, feeding insights straight to the FLOWBIO App.

From endurance pros to first-time ultra runners, it’s being used by athletes and coaches who want to fully understand how to maximise their training effort.

Why It Matters?

We measure almost everything in endurance sport. But sweat? Until now, it’s been ignored.

FLOWBIO puts hydration front and centre, helping you avoid cramps, maintain pace, and recover better, because you’re not guessing anymore.

Once you know your numbers, there’s no going back.
