This is true. On the lowcarb list, studies have been cited that
show improved performance after 3 or 4 weeks of adaptation to fat
as fuel.
When it comes to high-intensity anaerobic exercise, however, no
such adaptation is possible. The fast-twitch muscle fibers use
glucose and nothing else. How relevant this is to the demands of
triathlete competition is unknown to me, however.
