Beta heat equivalent temperatures

This is a beta version of a calculator to show the equivalent temperatures running and walking. Temperatures are calculated based on a specific height, weight and pace.

1 Notes

• The temperatures shown are how hot it would have to be for you to sweat the same amount when walking.
• Walking temperatures assume 30% humidity.
• The 'x% max' is showing what percentage of your maximum sweat evaporation is required to avoid heat build up.
• The entries 'Too Hot' indicate that not enough sweat will evaporate to keep your internal temperature stable.
• When the conditions are too hot, the approximate time for your core temperature to rise to a critical point is given as 'Terminal in x'.

2 Heat equivalent table

The table below shows an example set of equivalent temperatures for someone running 8:00 min/mile pace and is 174cm/70inches high and weighs 60Kg/132lbs. You can create a customized version of this table by filling in the form below
