Now that we've had the cyberspace hand shakes between our experts, I'd like
to ask some opinions, please. I don't have the practical experience that
many of you have, nor the opportunity to try out a lot of different things,
so I read what I can, and hope to interpret with your help. Scientific
articles, what works for you, or theorised opinion would all help me.

1. Resynthesis of muscle glycogen.
Some things I've read indicate that increased doses of oral glucose after
exercise do not hasten resynthesis of muscle glycogen, at least in the 24
hours following exercise.
This would seem to have implications for multi-days rides, when we are
expecting our horses to front up day after day.

What opinions are there on the practicalities of keeping horses going,
without detrimental fatigue, in multi-day rides?

2. Feeding before a ride.
This has been a controversial issue, apparently because of misinterpretation
between members.
It would seem to me from what I've read, and experienced in myself, that a
period of at least three hours from last meal to start of endurance exercise
would minimise any potential problems of insulin release and subsequent
substrate unavailability.

Does anyone have opinions on the optimum time for breakfast before a ride?
Or do you tend not to give the horses breakfast, just hay all night?

I thank you in advance for indulging my fascination with this area, and look
forward to further friendly discussion.

Happy riding,
Anne
