After RNY when did you start to run?

I posted this in the exercise forum too but I am curious when you all started to run after surgery.
I am having my surgery mid May. I am starting training today for a half marathon my 2nd in September. I will have 3 1/2 months after surgery to get ready. Do you think that is enough time if I have no complications? I figure worst case I just walk the course if I can't run at that point. But I wanted to see when anyone here did.
Thanks

Technically you just need to be cleared by your doctor for vigorous activity. I will say, however, nutrition is a challenge. Not an insurmountable one, but a challenge. Staying fueled to just LIVE is a challenge right after surgery, much less run.

To answer your question, I was about three months post-op but I hadn't run regularly before surgery so I started with intervals and worked my way from there.

Good luck!

Thanks that is a great point. I was thinking physical activity but left the part of eating out of my head. I am going to sign up worse case I do it walking or they get a donation and I cheer my friends on from the sidelines. I need to eat to live and at 3 months out I might not be eating my full calorie needs to do this. ugh but damn it I am going to try!

 See, that's the thing. I hope Paul or one of hte "real runners" answers because I just don't know. I know that marathons require rigorous training. But I don't know at what point they might have felt that was possible.

I do know around three months I started what I called the "Energizer Bunny" phase. I had SO much energy it was coming out of my ears! I didn't even sleep that much because I was simply  never tired. This lasted until about 18 mos post op. I also (blessedly) lost Aunt Flo for that time (damn her, she came back!!!). It was a very magical time.

But the months leading up to that I was a dead woman walking. 

 I loved that bunny stage!

Personally, 4 months post op I would not have been able to handle a half marathon, even if I were a previously experienced runner.  Nutrition is an issue and dehydration is HUGE.  I would not have been able to manage either of these things during that long of a workout.

Now, at almost two years I'm contemplating my first half and feel that I can do it.  I've done many 5ks.

I'm about 5 weeks out, and I started running this week.

I have a few advantages, though--I used to run quite frequently, I'm a "lightweight", and my recovery was a total breeze. Felt back to 100% very quickly. But by running, I mean that I can manage about a mile and half. On the treadmill. At a jog. Not street-running 13 miles.

Depending on many factors, others' timelines might be very different. Just do what feels comfortable for your body. Start slow, and build gradually. If it hurts (beyond just the "Omg, running!" discomfort) stop.

However, I don't feel it'd be responsible NOT to mention this - at 5 weeks out, about half where you plan to be when you have your 1/2 marathon... my body is in no way ready to be stretched that far. The kind of calories you burn running that distance--I can't eat half that many in a day, and I don't think my systems, at this point or at any point in the near future, would be well supported to burn that kind of fuel. You'd need to take in FAR more water than your pouch will be able to hold, and the risk of severe dehydration and muscle damage is high.

It's an admirable goal, but before you put your money down on registration, you may want to wait and see how your body responds to surgery.

FOR ME... I just started running, and I am 7 mo out.  The reason I just started is based off of the fact I just got down to 200 lbs, which was recommended by several sites and mr drs.  Anything more than 200 lbs and you can do a lot of harm to your joints.  Also it took me about 3 weeks to recover before I even felt like going to work much less running. 
I was not active before my surgery, so I am sure that plays into it all.   good luck.

I started at about 6 weeks post-op. Maybe a little later. I'll be four months out next week and I'm almost into week 7 of the Couch to 5k training. Have you run before? A half marathon is a lot..you might want to start with a little less distance?

 At 4 months out I wasn't sure if I could ever RUN 5K muchless 13.1 miles.  I had completed a 5K but lacked the self confidence to go much beyond that. I ran my first half at about 16 months but trained long for it.

My progression was 

5K
10K
15K
Half

I actually did my first Half by accident because I signed up for the wrong race.  for me it was many hours of running to train.  running 2 days througout the week and then getting up early in the morning to get in my long run.  I was stupid in my training and never really followed a plan and eventually ended up with injuries.  IT Band issues arund the 10K timeframe a bad knee at the 15K that last through the first half and then I ran my second half with a partially torn hamstring (Thought I had a cramp!).

For me the 2 biggest challenges are nutrition and hydration.  Most times I have no real intrest in food so I just eat because I have to, but when running I typically am not getting the correct mix of calories.

Like I said on the E&F Forum I'm not one to tell people not to try something just be smart in how you approach it.
