eck. I hate pukin. Cant say I've ever had a run induced episode. Dry heaving, yes, throwin chunks, no.
Somethings up. Def. NOT normal. Whats is your diet before you run? No dairy for a couple hours, as stomach acid pumps out a little more than normal in some people while runnin (me included) I actually avoid dairy for 1/2 a day before i run. Try pretzels...

i have thrown up after 2 races and i always get dry heaves...but go to the doctor

I don't think I need to go see a doctor really I think its mostly because my body needs to adjust because its not used to it. I'm pretty sure it has nothing to do with my diet though.

I know that is has happen to me in races (at the end before) and it used to happen to my dad when he was in his running prime. My theory is that my body just gets so hot and/or pushed to the limit that it wants to get rid of everything. I would agree with everyone else trying not pushing it so hard and see what happens.

I was surprised at everyone's 'go to the doctor' response. You might want to play it safe but I used to work out with marines and I'll tell you what it was definitely the exception to the rule when I didn't throw up at the end. I know exactly when it'll happen, I've just ran 3-5 miles and at the very end I have a gunnery sargeant calling me a pussy and all sorts of names so for the last 1/4 mile I kick it into high gear and of course I make it across the line and my body decides to punish me. I would think it is a simple case of pushing yourself hard. Whether or not it is considered too hard is up to you. I used to train really hard and about half the time I would puke at the end, I've since had to back off because of some other issues, but its not that big of a deal in my opinion. You can minimize the nastiness by watching what you eat before hand (ie little solids, mainly liquids). I wouldn't worry about it and just chalk it up to the fact that you are out of shape and/or willing to push yourself farther than most people. I saw one guy say it was embarrassing. Well the way I always looked at it is that if you see me puking my guts up at the end you know I gave it my all. I would much rather do that then be the guy finishing the line last and walking at that you know?

rob thats just great. but training with the marines is different than triathlon. for one thing your not getting shot at during the race....
Sethers is throwing up after a weekly training run .. not during a race. thats not healthy.

Agree with Triguy... you don't want your body to learn the vomiting response. If you're throwing up regularly after races, your body will start doing it automatically and you won't be able to stop. Can get fairly dangerous. Once in a while, after hard effort or a race... understandable. Every training run... do something differently.

Lol, I never got shot at although I might have perferred it to being chewed out by the sargeant lol. Obviously there are medically ramifications, I think the best comment was the fact that there are things you can do to limit it such as slowing down properly after the run. If you are drinking a lot of fluids it minimizes the discomfort of throwing up and the potential damage, since the stomach acid is diluted. As far as it becoming a subconcious unneccessary act, I don't think so. I think there is a difference between the dry heaves and throwing up. In my experience working out with various people some people react differently, some people just dry heave others just throw up.
I think the simply unpleasantness of the act of puking your guts up with be enough motivation for this particular individual to understand that it is undesirable and to take all the various steps to minimize the chance of it occuring. But that doesn't make it a bad thing. In most of my runs now i've learned not to eat anything before the run, I drink lots of water, and I generally try my best to push myself just to the limit of throwing up and then back off. I think this person will naturally learn how to do this too. Yes there is a difference between a recovery run and a push yourself hard run, but I'm the type of guy at least that has a lot more of the latter than the prior. I guess what I'm trying to say is instead of saying oh its really bad and you shouldn't be doing it and you should back off, you should be saying kudos for pushing yourself but man do you really like puking? Lets figure out how you can push yourself as hard but limit how many times you puke and how bad it sucks.

You all know I'm a begginer and have never done a tri and currently have only one month with my road bike. BUT I have been working out for a while now (swimm, bike and run).

I don't know if my comments are based on anything cientifical but here it goes. That problem happened to me on hard trainings as well. I didn't puke everytime but I sure got nauseus.

A certified aerobic instructor at my local World Gym told me that I was getting the problem because I didn't cool down properly. I have to agree with Amy Lee here that in my experience that was the problem.

After reading all your comments I think it might be possible that the same is happening to you guys. In a race it''s logical you go all the way and maybe you are not giving your heart time to recover properly after you reach the finish line with your heart rate near 180.

If you have this problem with regular training (as I did back then) you need someone or a book to teach you how to train. Back then I didn't have a clue how one was supposed to train and thought that if I pushed myself harder I would get better. AFter I learned how to train and stoped that nonsense of training near my heart max rate, learned all about base trainig etc. The problem disapeared.

Even when you DO train hard DO NOT stop right away. Give your body time to cool down and stretch your muscles I can almost bet the problem will go away.
