I am a little over 2 years post op, yesterday I ran my first half marathon in 2:37. I have run many 5ks some 10ks and 5milers. My suggestion to you is stop thinking its a bad idea. You want to do it, therefor you will! Sign up, research, and train! Use hills and read books. And don't give up! I couldn't even walk up a flight of stairs or from one telephone pole to the next without pain, breathing issues and exhaustion. -100lbs later and @ 205lbs I am a runner. It's hard work but I think yesterday was one of my proudest moments. Please feel free to contact me if you need anything. Run girl! RUN!
