Re: Marathon and LC -- found an interesting post

curt said:

Just to elaborate on how I feel on this subject. Keeping in mind that I
am
talking about my own experience. I feel many people can run a marathon
on
LC and some people can run a marathon on no food at all. It depends on
what
kind of shape a person is in. I can ride my bike for 40-50 miles on an
LC,
but after that time I need food (carbs) and fast. Now there was a time
earlier that I couldn't ride nearly that far on LC. I am convinced that
if
I was in better shape, I could ride for 60, 70 or more on LC, but right
now
I can't due to the shape I am in.

So IMHO, you can run a marathon on LC, but you need to be in very good
shape. I feel if you can run 26 miles on LC, you can run 36 on a carb
rich
diet. Just my findings for myself.

I also think it depends on what your output is. If you're time trialing
up a mountain, you'll have higher carb requirements than if you're biking
on flat ground with no wind.

When I haul my butt up a hill on a bike, I expend more wattage than a
lighter person would who is going the same speed. Conditioning factors into
ones ability to output watts. My guess is that you can train your body to
convert fat to usage energy more readily up to a certain point, but sooner
or later carbs will be needed (once you go anaerobic).

Glycogen is burned even before you go anaerobic. Because burning glycogen
requires 10% less oxygen for the same energy output, as your pace increases
the body will start to burn it, far before you go anaerobic. For example,
in the 50km race I did last week, my effort level was very high, but
probably anaerobic for only a few minutes out of over 5.5 hours. I burned
alot of fat and alot of glycogen, and I ate 800+ cal of mostly glucose, with
some protein during the race. Still, a majority of my energy came from fat.

You're correct.
