In hot conditions, your maximum running pace is limited by your ability to cool off. It is possible to calculate your theoretical maximum running pace at a particular temperature and humidity given your height and weight. This calculator is based on my [[Running Heat Model]].
=Introduction=
When you run, you produce heat that must be removed from your body. In cold conditions, this is not a problem, but as the temperature and humidity go up, it becomes harder to remove the generated heat. If you generate more heat than you lose, your core temperature will rise and you will have to slow down. For most people, the rise in core temperature causes a gradual, though unpleasant, slow down. However, extreme dedication can force some people to push hard enough to raise their core temperature enough to cause collapse, coma and even death.
In addition to the caveats in [[Running Heat Model]], the calculations of maximum pace make extra assumptions. '''This means that the pace indicated may not be safe'''.
