I plan to drink Honey as my source of glycogen for a Ultra Marathon of 80 Kilometers and 4400 meters D+, I'm planning to do it between 12 and 14 hours, so my question is How much milliliters of Honey would I need?
- ~50 miles.
- 3.8 mph (50/3.8 = 13.2) or 16 minutes/mile
- 792 minutes (13.2 * 60) = 4,391 calories (for a 170lb average person)
- Honey generally has 21 calories per 5ml, so that's 3 calories per ml.
- 4,391 (total calories) / 3 (calories per ml) = 1,463 ml.
Feel free to double check my math on all of that, and it's based entirely on the average of a 170lb person. Training, altitude, terrain, weight, temperature, and other factors affect this greatly.
Your body is also capable of storing, with carboloading, roughly 2,000 calories so theoretically you don't need to ingest 4,391 additional.
