The future for me, though, in the next year is going to be more running and such simply because I can't bring my bike on this deployment. I'll be interested in trying my 32-mile route in a fasted state while in ketosis to see how it goes. I'd bring some energy with me of course as a backup in case my body can't keep up, but I think if I keep my heart rate firmly in zone 2 I can probably do it.
Scroll down halfway on
this article on carb loading to read the method on brief HIIT to kickstart the body into more efficient glycogen storage. I'm still looking for independent corroboration of the method described, since I don't see any link in the article.
But it's easy enough to try. I already do something similar, although with a gradual warmup -- I need about 30 minutes to warm up before attempting any HIIT. Then I need a cool down period. In effect, it's similar to my usual 90 minute rides of about 30 miles. But I've been trying the methods described for Kenyan marathon runners, mixing in Fartlek training -- irregular bursts of sprinting along with the more gradual continuous training, without the rigorous timetable of HIIT.
