Sens 1 Pro
A wearable sensor you place on the back of your arm that lasts up to 14 days, providing real-time lactate data. By measuring from interstitial fluid, it delivers highly accurate insights to help athletes optimize performance, recovery, and training decisions.
A wearable sensor you place on the back of your arm that lasts up to 14 days, providing real-time lactate data. By measuring from interstitial fluid, it delivers highly accurate insights to help athletes optimize performance, recovery, and training decisions.
What is included?
The sensor consists of two components: a rechargeable electronics unit and a disposable patch that should be replaced every 10–14 days. Price includes patches for an entire year.
How do we measure?
We measure lactate in the interstitial fluid, a scientifically validated measurement of blood lactate. A minimally invasive micro-needle, accesses the interstitial fluid painlessly beneath the skin. No blood. No sweat. No discomfort.
Why measure lactate?
Lactate gives a direct measure of performance intensity, while heart rate can be affected by stress, fatigue, and other external factors. Measuring lactate allows athletes to train more precisely, optimize intensity, and improve endurance faster.
Your first box includes the rechargeable sensor electronics and a full year of patches. Once your year is up, simply renew your patches , the electronics are yours to keep, forever.

Why us
Benefits
Built by athletes, for athletes.
Train in the right zones, every session
Heart rate lags. It spikes when you're stressed, tired, or dehydrated, not just when you're working hard. Lactate tells you exactly where you are metabolically in real time. The benefit: no more guessing whether you're actually in Zone 2 or drifting into Zone 3 without knowing it.
Find your actual lactate threshold
The lactate threshold (LT1 and LT2) is the single most predictive marker of endurance performance. Right now athletes pay for lab tests once or twice a year to find it. With continuous data you can identify it dynamically and track how it shifts as fitness improves.
Avoid overtraining before it breaks you
Elevated lactate at low intensities is one of the earliest signs of accumulated fatigue and under-recovery. Catching that trend early means adjusting load before performance drops or injury hits.
Optimize recovery between sessions
Lactate clearance rate, how quickly your body processes lactate after effort, is a direct measure of recovery capacity. Knowing this lets athletes time their next hard session properly rather than guessing
ENGINEER YOUR ENDURANCE
Your threshold isn't a number from a lab six months ago. It's happening right now.

Welcome, Jack Roels.
Welcome, Jack Roels.
We want to welcome Jack Roels. The first NDURE Athlete.
Jack Roels is a young and upcoming Belgian triathlete. He qualified for the world champs in his first Iron Man. That event changed the trajectory of his life. Now he has 1 goal; go pro in triathlon and make it on to the world stage. That's why we support him. We want to help Jack reach his goals.

"I always push myself. This is who I am. This is why I joined NDURE"
"For the first time, I could see exactly when I crossed my threshold — live, during the ride."
