I usually feel a little nauseous for a few hours after my hard bike rides. It never affects me the next day though. I haven't really looked into it, I just have accepted that I won't feel good after most of my bike rides.

Yea this happens to me an hour or two after a long hard run! It sucks cause yu feel great
right after and eat a big breakfast or lunch and an hour to 2 hours later yu feel like shit!
I have been invited to an all womens nutrition seminar for athletes next week and i will be
defintely asking about this!:)

That has happened to me many times as well. I chalk it up to dehydration and electrolyte depletion, so to overcome it I try to eat a healthy meal after a long workout and drink lots of water along with an energy drink. Also, if you eat a heavy meal that is hard to digest, all that blood going to your stomach probably compounds the problem.

wow...i've never had this
hard to believe it's common!
keep checking and let us know what's causing it

This is definitely nutrition related. You're not getting something(s) or overdoing something(s) during your ride. Also need to make sure you're getting the right stuff after (and before) your ride. It takes some fine tuning, but eventually you won't feel like that after. Keep working on your nutrition plan!

It could be anything. Too many calories, not enough calories, overhydrated, underhydrated, sodium... I could keep going.
For me it was a combination of hydration and electrolyte replacement that I had to fine tune, along with getting a proper post-workout snack in. I have also had some times where I found it difficult to take in enough calories which would make me feel even worse post-ride.

I would guess nutrition too. Just as cuds is mentioning. How are you eating/drinking while on the significantly longer rides?

Also, probably a bit of overtraining included too, since you mention that the workouts that you get sick after are significantly further than normal.

I have this problem too. I eat a lot before, during and after exercise to the point of feeling bloated and still have problems. I need to think about what The Dude is saying about heavy food in the stomach and digestability. Perhaps I'm just not digesting what I eat fast enough.

My other theory is that I haven't trained my metabolism to burn fat at a higher level yet and that this is the cause of the bonk - burning too much sugar. I guess this goes into the category of overtraining.

I've seriously increased my fluid intake and that doesn't seem to help. Have even done so with Gatorade to get the electrolytes. No change.

This only happens to me when I put workouts together that shouldn't be, and the feeling sucks! Sorry , but try something new. Listen to your body, I've never really believed in all that fonie stuff about dealing with it. ofcourse in training you should be going past your comfort zone, but not to the extent of PHYSICAL pains!

quick question: is the onset gradual or sudden? If sudden, is it right after a meal?

if gradual, to me it sounds like you're not eating enough -- I've had this a few times, particularly during training camps. It is easy to underestimate how much food you need to stuff into you to compensate for the calories burned during a 6h ride -- particularly this time of year.

gradual onset is good news -- your training partners are probably right: not enough food/drink.
I have the symptoms as you when I don't refuel after a hard workout (even the case for hard workouts in the gym).

Eat, eat, eat;-)

liquid'ish meals get digested a whole lot better than solid meals, granted its a good meal. you can try oatmeal and blueberries or raisins after, or an MRS from a good company. cereal also is a great postwork meal. make sure you get plenty of all the electrolytes, not just sodium, and drink water. a lil bit of caffeine can help too.
