Running scared

Ok I joined cross country an I'm 17 and I have never join a sport before an I'm only doing it because it could be good to put on a college application. Im a skinny girl but I'm not fit so should I be worry, I dont work out and so I'm worry about the...

first pratice next week
so should I be?

Yeah, I agree. I suggest you start taking some running exercises / activities on your own free time or when you're at home. I would run // fast jog for twenty minutes straight. If you can't do that, just start slow with like ten minutes straight then slowly progress. Don't worry, you'll get better with practice.
*Walking also helps you build leg strength, but much slower, so you would have to walk for an insanely long time each day.
:D

I don't know if this is true at all, some people say running is '90% mental, 10% physical.'
Perhaps true or not true, just letting you know.

If you have physical education at your high school as well, that should help you too.
Hope this helps.

Cross Country Is Extremely Difficult. People Train For Months Before Actually Doing The Run. Doing a lot Of Working Out Should Help You. Take The Practises At Your Own Pace So You Can Get Ued To Them.
Hope I Helped :]
