How long should I wait to run after eating?

Hey all,

  Even if I eat something light and run, I get an ache in my abdomen. I have also tried running on an empty stomach and sometimes feel week. Looking for any recommendation.

    I will share what works for me first.  I eat a cliff builder bar approximately 2 to 3 hours before my run.  If i think I need something addtional I will utilize a gel pack like GU 10 minutes before my run.  That will be absorbed very quickly into your bloodstream.  What happens when you run is that your body shunts blood to the areas that need it the most such as your lungs, brain, muscles, etc.  If you have food still in your stomach and your body starts to pull blood flow away from it you will experience cramping, discomfort and possibly vomiting.  It is something you will need to experiment with to find what works best for you.  Good luck!

    I am another one who is by no means professional, but will share what I've done and works, learned from trial and error and some mild research.

    One hour before I warm up to run I eat one Greek Yorgurt and one full English muffin with a little butter. This way I get a lot of protein (yogurt) and my carbs (muffin). By run time my body is comfortable and I feel the most feuled. Keep in mind I run 5Ks, so if you are looking to run much longer than that this may not work at all.

    Generally at least an hour and a half.  You can train yourself to run with a full stomache, but that takes time.

    Like Raserei, I eat yoghurt. I have eaten the same breakfast for years and years: plain (but full fat) yohurt, toast or a bagel, a cup of coffee and some sunflower seeds. I'm fine to run an hour after my last bite.

    Hi, I usually eat half of a banana or 1 piece of dry wheat toast. Experiment and see what works for you

    You might have to try different timeframes (and foods) to see what works for you. Generally I try to wait a minimum of an hour, although there have been time crunch times where I just had to run even if I just ate. I usually have coffee in the morning and maybe a protein bar or fruit, and an hour is good. Hydrate before but try not to go run when you have water sloshing around still.
