If you lose weight, it is recommended to do aerobic exercise for more than 40 minutes. Whether it is running, cycling, brisk walking or aerobic exercise.

I suggest you keep the speed above 6km/h and run for 40 minutes. As for the number of laps, it depends on the specific speed and the perimeter of the playground.

Reasons for suggesting 40 minutes: Lipase participates in lipolysis. Generally, aerobic exercise takes 20-30 minutes for lipase to be active, so aerobic exercise needs to last for more than 40 minutes to lose fat.
