It's not about the running but the "running through sickness and fractures". It's just plain stupid to risk your health like that. Great that it worked, but this is nothing anyone should blindly emulate. Have fun with the heart infection because you needed to run for virtual internet points.

Scientific information on the topic is quite sparse. There are ascientific recommendations about vigorous activity that probably have some merit, but unless you are terribly, terribly ill, a very light workout is not known to increase adverse health outcomes.
