conditioning for 100's

["B. Miskimmin/J. Curtis" <limnos@junction.net>]

Hi,
It sounds like you did everything right to get your horse ready for 100s.
One thing you didn't take into acccount is your horse's innate knowledge
that her ride should be over by now!  She has done so many 50's for so long
that she knew she should be done.  Sounds like it's not her physical
conditioning, but her mental preparation for the distance.  Were you riding
with another horse (which helps)?  Maybe you should try some 75s, then go
for that 100 again.
good luck,
Brenda
