thermal energy, mechanical energy  and chemical energy.

Explanation:

Our body goes into catabolism during running. Complex stored food molecules are broken down into simpler molecules that enter the blood stream and provide energy or fuel for running.  

Mechanical energy is the sum of the kinetic and potential. During running we move our limbs, set our body in motion and cover a certain distance.  Thus we utilize mechanical energy.

Thermal energy is characterized by a change in temperature. When running there is an increasing in body temperature which is manifested as sweat from the body.
