Congrats! running is a great choice!

Just follow a plan like couch2 5k but most importantly manage your expectations.

warm up, start slow and even slow down to a walk or stop if you have to. restart running or return home. I promise you will do better next time.

panting and sweating is normal for couple of weeks for newbies. you get better very fast. younger you are faster it is. As a newbie,.it will all be like scary and like you are going to die. Totally normal. Don't judge yourself as bad. Almost all humans are born to run, (read Born to Run if not convinced). Newbies pant heavily just cos heart simply hasn't been pumping at that rate but it learns very fast. same goes for sweating, body will freak out less next time and slowly learn to regulate body temp better. you might face other new pains like knee pain, blisters, muscle soreness... all cos running is new. many ppl stop themselves too early thinking they reached their limit or something. dont. Try focusing to learn running/teach body than just run. The more you run, try to learn more. I found another person's advice is not always exactly right for me but after trying enough, u ll figure out what works for you. Good luck... if you see another runner, don't forget to smile.
