Running (Beginnner need advice)

Do a search on couch to 5k (c25k). It is a great 5k training program alot of people here use it.

Go to a running store and get fitted for good shoes - this is really critical to remaining injury free. At a running store, they should have you walk/run a little bit (in the store or on a treadmill) so they can see the way your foot strikes and then they can recommend the right type of shoe (stability, regular, etc..). Running shoes may be a bit more expensive, but they are really worth the investment.

Also, work on endurance first, not speed - a lot of people get discouraged because they try to run at top speed and can't go very far - the slower you go, the farther you can run, so work on that first, and once you can run the target distance and longer, then start incorporating some speedwork. Escalating run/walk intervals are the best way to accomplish this.

As someone else recommended, look into the c25k training program/schedule if you want to go it alone, or see if there is a class through the running store or a local runners group, where they group you by ability levels - I started (and continue) with classes and find it really fun and motivational to run with other people at a similar level, with a coach, but to each their own. The important thing is to have fun - good luck!

I got scared, I read c25k as "couch to 25k"

I always go outside to run and I mix it up. I like going to different routes and trails. I especially like hills. It's a good way to build up endurance too. variation is a good way to keep things interesting and keep from boredom setting in.
