I doubt it. If you are experiencing this, hyponatremia, severe dehydration, or many of the other things mentioned in this thread then there will be major performance problems. It is like bonking but even worse and just consuming calories does not fix it in the short term, even if they those calories contain electrolytes. The hole that has been dug is too deep to fill in a short time. You will know that you are in a bad way because you will be struggling to go keep cadence on flat ground in a low gear.
No, but I rarely drink the stuff.Back in the summer I was chatting with a cyclist at a rest stop during a long charity ride who mentoned that he is diabetic. He said that Diet Coke elevates his glucose levels. I was quite surprised to hear that since it contains an artificial sweetner. Have you experienced the same?
After a 30 minute Crit I passed out 10 minute into a cool down. This is more dangerous because I was still on my bike. So far the best theory is from low blood pressure. Where the views in the legs are still expanded but the heart rate has shown down. KAfter a 90 mile ride with 6000 feet of elevation gain, in 95 degree heat, I dismounted, and about 15 minutes later passed out and just keeled over. Never happened before. Two doctors could find nothing wrong but said maybe I could have prevented this with a cool down ride at the end. Is it a good idea to do a cool down ride after a long hard ride? Do others do this?
