In shape, but don't run

I was in the same situation a couple of weeks ago. I started with the C25K program but skipped to week 3. You will do some shorter runs with walk breaks in between. You really need to train yourself to run so I highly recommend following this program. You'll find different parts getting sore that you never felt before.

I didn't go out and get fit for shoes at a running store but that's the right way to do it. Proper shoes will help correct pronation issues.

I also suggest you visit a running store and get shoes fitted for you. It will make a big difference with comfort and injury prevention, especially if you decide to make running a regular exercise routine.

There are many dedicated websites to running, that there are too many to mention but just do a search and you'll find a wealth of information on nutrition, tips and running gear.

Good luck!

Even though you don't consider yourself a beginner, start off slowly. The last thing you want to do is get injured and derail your running career just as you're getting started.

Put your left foot forward then your right then your left then your right. Quite quickly. Repeat until tired.

Just don't put your left foot forward then back then forward then back or you'll be doing something else.

The question that is on my mind: why do you want to run? Do you feel you have to in order to achieve your goals? I mean, you sound like you're doing a hell of a lot of exercise already - more than enough if weight loss is your goal. I mean, whilst I encourage people to do exercise they enjoy, I never run. I lie - I did do about 15-20 minutes to see what this minimalist running was about.

This.
You may be in great cardiovascular shape, but running is more than that. Your bones and your muscles are going to have to adapt to the rigors of running, and this may be more challenging than you think. It is very easy to injure yourself by doing too much, too soon, when it comes to running....so take it slow at first, even if you don't feel especially challenged in the beginning. Have fun!

Ditto.

I lift weights, bicycle, and do various classes like bootcamp, cardio-kickboxing, spinning, and can easily do an hour on the elliptical (although I rarely do because it's pure boredom so I just do it for shorter HIIT durations). I completed a two-day 200-mile bike ride in July and did numerous rides of 30, 40 and 50 miles over the summer. Then I decided to start running.

Man, oh, man. I thought I was gonna die. Cardiovascularly, no problem. At the speed I could run, I wasn't even breathing heavy. Muscles and my body's ability to take the constant pounding, yikes! And I figured with all that other work, that my muscles would be strong for running. Nope. I am still carrying too much weight (working on that still) so I know that was part of the reason the pounding was hard on my body. And it is getting better, a lot better. But I still have to limit my running to no more than twice a week in order for my joints to recover from it. I can go to bootcamp the next day and do burpees and jump-squats like crazy but I sure can't run the day after running or my knees/ankles would be screaming at me. Go figure.

You may run like a gazelle out of the gate or you may struggle like I did. You can try C25k to get yourself started and jump ahead if the first few weeks are too easy. Or you could be like me and need to repeat weeks. If so, don't sweat it. Just do what you can do and put on those shoes and get going.

Oh, I found the C25k too regimented for my tastes so, after a few weeks, I scrapped it. Nothing against the program. Many people love it. I just found that I pushed myself harder if I just did it more fartlek-style. Whatever works for you.

Running is awesome but will take a toll on your body.

I agree.

You may be surprised if you start running outside how hard it is. I was in really good shape when I decided to start running. Figured it would be a breeze but I downloaded C25K onto my iPod and started out. All my cycling and workouts that I thought had me in such super shape was a joke. I ended up doing weeks one to five and then just running from there.

I'd really recommend getting fitted for good shoes at a running store before you start. I thought my shoes I wore for my other workouts would be fine and ended up messing up my knee.
