About Sweatr
Every athlete deserves a sports scientist in their pocket.
We built the missing layer between your wearable data and the fueling guidance you actually need on race day.
Why we built it
Your wearable captures everything. It just doesn't tell you what to do with it.
Endurance athletes were spending hundreds on watches and gadgets that tracked everything — heart rate, sweat loss, training load — and still hitting the wall on race day because nobody told them what to eat and drink.
Garmin, Apple Watch, Strava — the data has always been there. What was missing was the layer that turns that data into a personalised fueling plan timed to your actual effort. That's what we built.

Our mission
Personalised fueling guidance for every endurance athlete — built from real data, not someone else's averages.
What we believe
The right advice, built around you
Science, made simple
The science behind hydration and fueling is genuinely complex. Our job is to make it invisible. You get a simple plan that works — all the clever stuff happens behind the scenes.
Your data, not averages
One-size-fits-all advice is the reason most people get it wrong. Sweatr builds your plan around you — your body, your training, and the conditions you'll be in on the day.
Built for everyday athletes
Professional athletes have always had access to personalised fueling advice. We're building the same thing for everyone else — the runners, cyclists, and triathletes who train hard and take their events seriously.
No noise, just actions
We don't want to give you another dashboard full of numbers to figure out. Sweatr tells you what to take, how much, and when. That's it.
Who Sweatr is for
Serious about your events. Not a full-time sports scientist.
The first-timer
Training for your first big event. Overwhelmed by conflicting advice about what to eat and drink. You just want someone to tell you what to do — and Sweatr does exactly that.
The regular racer
You've done a few events. You've had a bad race day — maybe you hit the wall, maybe your stomach gave up. You know something needs to change, but you're not sure what.
The performance obsessive
You train seriously and track everything. You've optimised your training plan — now you want your fueling to be just as dialled in. Sweatr is the piece that's been missing.
