sport.running-heat-index-risk Calculator
Calculates running heat stress risk from temperature and humidity using the Heat Index, and flags whether conditions are safe, cautious, or dangerous for sustained effort. Above 103°F heat index, the body's cooling system starts losing the battle — bonk and heat stroke risk spike.
Inputs
Air Temp C
Thermal state of the substance. Check whether the formula needs Celsius, Fahrenheit, or Kelvin (K = °C + 273.15).
Humidity Pct
Reference formula or conversion factor shown for context.
Run Intensity Mets
Reference formula or conversion factor shown for context.
Body Mass Kg
Total mass of the body. Used with height to calculate BMI and estimate lean mass.
Results
heat index (°C)
A normalised score comparing the result to a reference baseline.
sweat rate estimate (L/hr)
The value at the specified point or condition.
risk level
The measured or computed level on the applicable scale.
fluid replacement needed
Sample size or count used in the calculation.
WBGT threshold
Reference formula or conversion factor shown for context.
electrolytes
Reference formula or conversion factor shown for context.
