I hope this topic is more common than i suspect.
I raced yesterday - MTB endurance based on 12 mile loops for ten hours. I quit after five laps b/c of nausea. This has happens to me frequently - i had horrible nausea during the 2nd half of the Leadville 100 three years ago. I find the sensations hard to describe - hopefully the points below help and are directional correct. (Context: CarboRocket in the camelback @ 50oz and 1 GU Gel each lap)
- Sensation of ‘gulping’ air while drinking
- Sensation of asphyxiation while drinking. I suspect this is the result of taking in nutrition while having an elevated heart rate and elevated respiration but i don’t take in nutrition while descending, (i’m too scared to do anything else with my hands)
- Increased feeling of foregut pressure / bloat as the race progresses
- Feeling of ‘sloshing’ in my stomach
I never deal with nausea in training so i am struggling to figure this out. Is it the adrenaline byproduct of the event? Should I change brands of nutrition? Should i drink more slowly? Is it normal to feel hypoxic from 1.5 seconds of not breathing while drinking nutrition at race pace?
Dang, i am frustrated by this - hoping that you all have some insight!
