My advice:

01) Have a healthy breakfast before starting physical activities;
02) Do stretching before beginning physical activities;
03) Wear proper and good quality sneakers;
04) Run in a relaxed way, so that the feet and legs become relaxed, as running causes a high impact on the lower limbs;
05) Respect physical limits;
06) Avoid climbing stairs over several floors unless absolutely necessary;
07) Avoid running a long route without being accustomed to this distance and time.

So the ideal would be to start running after getting used to that distance and gaining muscle. Then gradually increase the distance to be traveled as long as you respect the physical limits of the person. It is necessary to have patience and objectivity in the execution of physical exercises.
