When did you start running?

I have recently started exercising regularly at the gym and I'm wondering when people moved from walking to running.  At 280 lbs and 5'7" I don't want to damage my knees by running but want to try running when it's safer, any advice?

I recently started the couch to 5k program.. it might be a good starting point for you, as well. http://www.coolrunning.com/engine/2/2_3/181.shtml I did week 1 for 2.5 weeks, and just started week 2 (which I also anticipate doing at least 2 weeks).  It's good because it builds up endurance in levels and encourages you to go at your own pace.

I started the Couch to 5k program about 3 weeks ago. I have had no problems with my knees whatsoever. When I was heavier It was an issue and the pain was terrible but as I lost weight and started working out it improved and now I train with no pain at all. I'm 5'8" and 245.

I waited until I had a good solid base of walking in.   When I got  the walking speed so that it was uncomfortable, I started running.  That was at about 4.3 mph.  At that point it was just easier to run.  I would guess that I started running at about 3 months out after walking for about 2 1/2 months.

The couch to 5k program is a good way to start. I started when walking didn't feel challenging enough and I wanted to kick up the challenge.  I started working in short (maybe 30 sec) running intervals about 5 months after surgery.  Starting slowly with walking/running intervals is a good way to give your body time to adjust to the demands of running and hopefully stay injury free.  Good luck!

I tried moving from walking to jogging at my 4th month post-op but at 294, my shins hurt, so I just kept walking. 3 months later at 266 I could jog without my shins hurting and it has taken off from there.  3 10Ks, a 5 K and 1 8K in 13 months since.  I am also registered for my first ever half marathon (13 miles) in Nov.  Just stay with the program, it works if you do.  You sound like yuo are doing a good job and are about ready to make the jump to jogging soon.  NOTE: Good running shoes are essential for avoiding feet, leg and hip/back pain.

Thanks for all the great advice. I'm going to keep walking until my pace becomes too fast to walk comfortably at.  I'd like to get another 50 lbs off before I start running.  I would hate to screw my knees up. I actually bought some running shoes to prevent injuries.  Of course I have flat feet and my feet pronate so I needed some decent shoes.  I got a pair of Brooks The Beast for $120, I almost fainted at the cost but they have made a huge difference to my comfort. The Couch to 5K program looks interesting and I think I might give it a try once I move from walking to running. So hard to believe that a year ago walking 100 yards would get me out of breath and now I'm talking about running.

Hi - I started running last August.  I had been doing walking, elyptical and swimming before that.  I did the Couch to 5K program and ran 2 5K's in November and loved it!  I'm now training for a 10K.  Couch to 5K was great because it was gradual and they gave you "permission" to repeat weeks as needed. I was also worried about one of my knees.  I talked to my surgeon about it and she wrote an order for some time with a physical therapist before I started running.  That helped me build up some muscles and learn how to run correctly, etc.  I think it helped - knock on wood - no injuries yet.  My knee does feel funky now and then but I'm good about stretching and I ice if needed.
