This is a running challenge where I have to run for 30 secs and then rest 30 secs and start running again. I will be running and stopping for 20 minutes trying to hold myself the best.

This was a custom video request and a good video for likes to see a woman exercising and then to watch getting tired and breathing hard from running.

PS: Microphone on sports bra so will be more clearly to hear me speaking and breathing, also to avoid the loud sound from the treadmill.
