<< I agree fully with what you say Heidi, although I think it is 
 possible that carbs provided during exercise may aid performance in 
 horses.  Human athletes usually compete in ultramarathons while 
 working at an intensity corresponding to about 50-60% of their 
 aerobic maximum.  At these intensities fats provide a large amount of 
 the energy needs.  To your knowledge, is there research out there in 
 horses that looks at substrate use at various relative intensities, 
 and do we know what % of maximum horses are able to maintain over 
 races lasting 10-24 hours?  >>

Thanks, Beth.  Yes, the use of extra carbs as an "aid" may be useful, but as 
you say, even in humans, it is not a fat-vs.-carb thing but rather a "joint 
effort."  As to the research--Sarah could probably give you more specifics.
