Re: RC: heart rate - fit to continue criteria



Thank you Steph for the lead in.

This is what the speakers at the upcoming SERA (Southeast Endurance
Riders Association) are going to be talking about. The first talk is on
the roll of electrolytes in the endurance horse - the whys and hows -
given by an expert on the biochemistry of electrolytes.  The second is
going to be on metabolic problems and will have much information that
has been learned at the Biltmore the past couple of years which had the
type of problems you were talking about, Steph.

It is going to be on 22 Jan and the details are in the SERA newsletter.
Anyone interested in going but who doesn't get the newsletter, can
contact me privately for more information.
