I warmed up for about 15 minutes at a relatively easy pace and was about to start some tempo running. All of a sudden the tunnel vision came on and then I was on the deck. I was at the gym so a bunch of people rushed over right away. I felt fine right away, just a bit shaky. I think I must have been dehydrated or something because this has never happened before.
Have any of you passed out in a similar situation? Kind of scary but feeling ok now after about 2 hours.
That must be some pretty severe dehydration I would think…might want to get that checked out…
Seen it happen a few times. It’s more frightening when someone goes black on a bike, on a road, in traffic, at speed.
Anytime you lose consciousness it’s a good idea to consult with a physician. It’s not a normal part of training, not a normal part of recover, not a normal part of life. When the lights go out it’s your body’s way of telling you there’s something wrong. Find out what it is so you can eliminate some of the associated worry. It’s nice to train hard without the fear of fading to black. It’s only cool in 80’s music videos.
Be safe,

For sure see the MD but it sounds more like either a drop in blood pressure or a tanked blood sugar.
I agree 100% that you need to go and get checked out. It could really be a number of things, some of which are life threatening so it’s better safe then sorry.
Like 0G said, passing out is never normal so there is something going on that needs to be diagnosed. Even if it is dehydration or a bad bonk, you need to see a Doc.
This happened during my last indoor tri, on a spinning cycle. The lady did not get clipped out in time, fell over with the spin bike on her. Yikes.
I had atrial fibrilation a couple times that caused me to almost black out on random workouts. An ablation fixed the issue, but as per everyone else…get checked out right away.
One of my friend’s wife would faint on a relatively consistent basis. They took her to several doctors and never really got an answer. The best they got is, “some people just faint.” Not a very satisfying answer and really left them worrying.
Definitely get it checked out. Probably dehydration/overtraining, but it could be something worse.
I remember reading this a while back. It’s about V-tach.
(pink) HTFU … how are you going to ever make it in a race if you can’t even do a run on a treadmill? (pink)
Scary; hope you can figure out why. Low blood sugar is something else to consider w/ dehydration.
Did you land on the moving belt?
I have no advice, but wanted to say glad you’re OK.
My former wife was a residential property manager - one time she had someone pass out on a treadmill at one the apartment complexes she managed. The guy was in the fitness center alone at 11:00 at night, passed out for several minutes and landed with his face on the still-moving belt. Needless to say, the result wasn’t pretty. On some level, treadmills have scared the crap out of me ever since. As uncool as it might be, I still use the little lanyard safety thingy because of that experience.
Glad you had help nearby and glad you’re OK.
I had stopped to check my HR and I was at about 140-150. I was standing on the sides of the machine and I had turned it down to about 4 mph. Felt fine while running but when I stopped is when I started to pass out. I was out for only a second or so, but enough time to fall. I am in the 3rd week of base 2 training and coming off a hard weekend.
Looking back over the past day I have not drank enough water and I feel quite sheepish about admitting to that. I know much better.
For what it is worth, I am 26, 160lbs, 5’10 and have been racing tris for 4 years. Never had anything like this happen before, but this is the first year I have started to follow an actual training plan and am working out much more than I have in the past.
Thank you for your replies, I’m drinking water and eating as I write this.
It sounds like you went orthostatic suddenly. Why is the question the doc will want to know? That should not happen after being vertical for a while. Get ready to be frustrated w/ testing especially with no pattern in your history. Get it checked though. Had you eaten semi recently beforehand?
I would see your PCP. I know at 26 you still feel invincible. (I’m 28) It could be nothing at all or some more serious.
Hope all goes well.
This happened to me twice in the past when I tried to workout in the morning without eating. I went hypoglycemic and passed the F out. First time it was after a short run. I felt woozy, saw some silverish looking spots, so I stopped and next thing I know I woke up on the ground a few seconds later. The next time (a few years later) I was on the treadmill and didn’t get off in time. got a little bit of belt rash on my arm and shoulder out of that one. I never use a treadmill without the kill-switch hooked to me now. But it hasn’t happened to me in several years since I learned not to train in the morning without eating something first.
Breakfast about an hour before. Banana, trail mix bar and coffee with cream and honey.
Just to pile on, go see a doctor. To answer your question, yes, I’ve had it happen. It could be for any number of reasons. My syncope was actually brought on by an exercise induced allergy with a food trigger - in other words, eat the magic food, then go run, and Voila! Kissing the kitchen floor. Mine was due to a drastic drop in BP - a clever way for the body to get you horizontal and the blood flowing again. I had never had it happen before, and now that I think I know the trigger, I hope to never have it happen again. Hope everything turns out alright, but by all means have it checked out.

That’s a breakfast? 
haha, no def not a breakfast. Should have said “snack”
My stomach is easily upset when I eat and run. I usually eat light before I run.

I’m the same way- it’s hard to balance enough cals with not upsetting my stomach…
If you didn’t eat a lot the night before, you may have been hypoglycemic. I would still see an MD, though.
