Why do I puke 3-5 minute after I race?

Be careful with taking pepto. It neutralized the acids in your stomach so you are more prone to getting food borne illnesses. If you need it, you need it, but be cautious.

As far as the throwing up part goes, does it feel like you're heaving because your stomach is upset, or does it feel like someone is sticking a finger down your throat?

Kind of hard to explain but I would say more so that my stomach's upset.

I used to do this when I was in highschool on hard workouts. Almost always on ladders and quarter repeats. Back then (early 2000s), all we ate was pizza and french fries for school lunch topped down with chocolate milk. Couple that with the heat of track in the spring or cross country in the late summer and it was a disaster. I'd suggest watching what you eat and how much you eat prior to practice or a meet. Also, don't chug a whole lot of water and try to sip on some electorlite leading up to the event. Lastly, think about adding some volume during the week just in case your intensities are to high for your fitness.

idk if any of that will absolutely help, but give it a shot. Watch what you eat or eat better; don't chug to much water; potentially increase fitness with some volume.

What I can't understand is that I can push hard in practice and not have any issues. Whether it be mile repeats, 400's or anything else, I feel fine.

Probably nerves. Do you feel antsy or anxious at all leading up to a race? Maybe it is all the tension and then once its over you just lose it.

Not any more nervous than anyone else about to compete. If you aren't at least a little nervous there's something wrong with you.

Are u pregnant?

The poster who said nerves is correct - but not nervous nerves, central nervous system nerves. I had a similar issue where the effort from the race tightens up the mid-back and this can cause a nerve spasm. On the opposite end of that nerve running from the mid-back is the diaphragm which, when you're tight after a run, squeezes the stomach and ends up with puking.

Work on stretching the mid-back. If you're the type that believes in it, a chiropractor might also help.

Definitely not pregnant. lol

So did the stretching help you? If so, what particular stretches?

Drink water with electrolytes (Nuun tablets, not Gatorade) before and immediately after the races. Water is not your friend.

Hey bro

Maybe its because your body can’t handle the sudden change in intensity. Do a brisk little jog (slowing down over time) after your race to lower your heart rate. Force yourself to get moving less than a minute after running if you can
