# How many Honey do I need for a UltraMarathon 80K and 4400meters D+? [closed]

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?

• This question appears to be off-topic because it is extremely narrow and hard to imagine it could be relevance to anyone else. Also extremely difficult to answer accurately. – Eric Oct 5 '14 at 21:47
• @EricKaufman - Why on earth would you vote to close and then answer the question? – JohnP Oct 6 '14 at 19:37
• @JohnP I answered it first, then reviewed the criteria for closing, and thought it was pretty narrow and constituted a close vote. – Eric Oct 6 '14 at 19:51
• @EricKaufman - Fair enough. Just seemed odd. :) – JohnP Oct 6 '14 at 20:50
• Long distance nutrition seems pretty on topic. This is a concern for anyone doing long distance since a marathon is at or above the body's limit for energy storage per popular opinion. "Difficult to answer accurately" is exactly why this should be an open question. – Jason Jun 28 '15 at 15:33

So that's:

• ~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.
