01 · SWEAT RATE
How much fluid are you losing?
Estimate fluid loss over time so you can plan around the demands of your sessions and events.
Mobile Sweat Testing · Calgary
Know what you lose. Plan what you replenish.
Measure your sweat rate and sweat sodium, then turn those numbers into a hydration strategy you can actually use in training and racing.
Why test?
Hydration gets easier when it is measured.
Generic sodium and fluid targets are a starting point. Your own sweat response gives you a better basis for planning long training days, hot races and higher-volume blocks.
02 · SWEAT SODIUM
How salty is your sweat?
Measure sweat sodium concentration rather than relying on appearance, taste or guesswork.
03 · APPLICATION
What should you do with it?
Translate the measurements into practical fluid and sodium guidance for your training and racing context.
What you receive
A result that changes the plan.
The point is not to leave with a number. It is to understand what that number means when you are deciding what to carry, drink and replace.
✓Measured sweat rate from the testing session
✓Sweat sodium concentration
✓Estimated hourly fluid and sodium losses in the tested conditions
✓Individualized guidance for applying the results in training and racing
✓Interpretation in the context of your sport, event and environment
How it works
Turn your sweat profile into a hydration plan.
1. Book
Choose a time through the Tempered booking calendar.
2. Test
Complete a standardized exercise session while sweat losses are measured.
3. Analyze
Tempered calculates your sweat response and interprets the result.
4. Apply
Use the output to build a more deliberate hydration plan.
Who it is for
Especially useful when conditions get complicated.
You do not need to be an elite athlete. The test is most valuable when hydration matters enough that guessing is getting in the way.
Long-course & endurance events
Marathon, ultra, cycling, triathlon, rowing and other events where fluid and sodium losses accumulate.
Hot-weather training or racing
When environmental heat increases sweat losses and makes your normal hydration routine less reliable.
Heavy or salty sweaters
For athletes who notice high fluid losses, salt residue or large differences between cool and hot sessions.
Athletes tired of generic advice
When you want your hydration plan based on your own physiology rather than a one-size-fits-all chart.
Sweat testing
Initial test + retest
Start with the full $237 sweat assessment. If you have already completed a Tempered sweat test, a $99 retest is available when there is a real reason to expect your response may have changed.
✓After a heat-acclimation cycle
✓After a significant change in dietary sodium intake
✓When your sweating response has changed meaningfully in recent training

FAQ
Common questions.
Is one sweat test enough?
Usually, yes. A retest is most useful when there is a reason to expect your sweat response has changed, such as after a heat-acclimation cycle, a significant change in dietary sodium intake, or a meaningful recent change in how much or how heavily you sweat.
Does this tell me exactly what to drink every hour?
It gives you measured losses to work from. Your final intake still needs to account for event duration, temperature, access to fluids, gut tolerance and what is realistic on course.
Is this only for runners?
No. Sweat testing is useful across endurance sports including cycling, triathlon, rowing and hybrid events.
Where does testing happen?
Tempered is mobile and serves athletes in Calgary. The exact setup is arranged around the test and your training context.
