As a physical education specialist and sports enthusiast, I'm thrilled to delve into the fascinating world of energy and how it relates to the act of running. Running, like any other form of physical activity, involves the conversion and utilization of different forms of energy. Let's explore the primary types of energy at play when you run.

Kinetic Energy
First and foremost, kinetic energy is the most directly involved when you run. Kinetic energy is the energy of motion. It's the energy that an object possesses due to its movement. When you run, your muscles contract and extend, propelling your body forward. This motion converts stored chemical energy in your body into kinetic energy, which is the energy that keeps you moving.

Chemical Energy
Chemical energy is stored in the molecules of the food you eat. This energy is released through a process called cellular respiration, where glucose and oxygen are converted into adenosine triphosphate (ATP), the primary energy currency of the cell. ATP is then used by your muscles to perform work, such as running. The process of converting chemical energy into kinetic energy is a complex biochemical process involving multiple steps and enzymes.

Potential Energy
While not as directly related to the act of running as kinetic and chemical energy, potential energy is still a factor. Potential energy is the stored energy of an object due to its position or condition. In the context of running, this could be the potential energy stored in your body's muscles when they are contracted, ready to release energy for the next stride.

Thermal Energy
As you run, your body generates heat as a byproduct of the metabolic processes that are converting chemical energy into kinetic energy. This is known as thermal energy. Your body has to work to dissipate this heat, which is why you might feel warm or sweat during a run.

Radiant Energy
You mentioned radiant energy, which is a form of energy that travels through empty space in the form of electromagnetic waves. While radiant energy is not directly used in the act of running, it's worth noting that our bodies do interact with radiant energy in the form of sunlight. Sunlight can provide warmth and stimulate the production of vitamin D, both of which can have indirect effects on your running performance.

In summary, when you run, your body primarily uses kinetic energy to move, chemical energy to fuel that motion, and potential energy, thermal energy, and radiant energy play supporting roles. Understanding these energy conversions can help athletes optimize their training and performance.
