In brief: Fever going up
One of the factors in producing an increase in body temperature is muscular activity.
A long distance runner will generate very high body temperatures. One of the ways in which the body produces an elevation of temperature is by chilling, which is a form of muscular activity. The other factor is the differential between the body temperature and the external temperature.
