Every horse, every situation is different. But at Biltmore
I dosed elecrolytes every hour (10 miles) and 30cc probiotics
at every hold (every 15-20 miles). Khruschev ate and drank
wonderfully all day - his gut and hydration parameters
were A at every check. The only thing that wasn't the
norm with him was the heart rate - both working heart
rate and recovery time were a little higher than
normal - probably due to the heat and humidity - pumping
blood faster to the skin and lungs to lose the heat. ?
His respiration was never elevated though - no
panting. Definitely another 'learning' ride. In retrospect
I probably could have continued on at a more competitive
pace instead of taking the extra time after the 75 mile
hold. But this was our first 100 in such extreme conditions,
and I had some new 'signals' that I didn't quite know
how to interpret. I rode with an under-saddle temp gauge
and he stayed quite low all day - never over 101 skin temp,
generally between 99 and 100 - so his working temps were
quite good. I think the biggest thing I could have done
different was to be more aggressive when cooling during
the holds. I used more electrolytes and probiotics than
ever before - and I think it helped.

 gut flora to die off can be a problem.  Adding to problem is the
 stuff these gut flora release as they die off.   Thus adding a lot of
 extra pro-biotics before the stress begins may increase the bad
 stuff released once the stress begins. Perhaps it would be better to not
 pre-load probiotics (or only in very small amounts to counter possible
 pro-biotic kill from the 'lytes') and only start giving pro-biotics
 once the stressful activitiy has started -to replace whats dying off?

That is an excellent point Teresa.  We don't give pro-biotics until the last
loop of the race (usually at the 35 mile mark if it works out that way) only
lytes prior to.
