Sample Sweat Report

Meet Tempered Taylor.

Taylor is a fictional ultrarunner used to show what a Tempered Sports sweat-test report can look like. The numbers are realistic sample data, not a real athlete record.

Your Sweat Profile

Measured physiology, not a generic chart.

The report starts with what was actually measured, then places it in descriptive athlete context without labelling higher or lower as better.

Race Translation

What might this mean over 6½ hours?

At the same sweat response, Taylor would lose roughly 8.5 L of fluid and 7,180 mg of sodium across the 50 km ultra. That does not mean Taylor should try to replace every litre or every milligram while racing.

Interpretation

Losses are context — not automatic replacement targets.

Taylor's sweat rate is meaningful over ultra duration, but the practical plan still needs to fit aid-station access, gut tolerance, race temperature and how much fluid Taylor can comfortably take in while running.

✓Fluid strategy starts with race duration and access.
✓Sodium is considered alongside the amount of fluid actually being replaced.
✓The plan is rehearsed before race day rather than treated as a fixed prescription.

Taylor's starting bottle setup

At 750 mL/h, Taylor would drink about 1 × 750 mL bottle per hour.

The bottle builder helps connect hydration and fueling so the athlete is not given separate numbers that do not work together on course.
