"... recently went on a Ride
and Tie ride, the short course, 6 miles, and at the ending vet check, my horse's
heart rate never dropped below 82 and her muscles were
twitching......."
If she is in good shape, 6 miles
may not be enough to get her calmed down from the pre-ride excitement.
Since she got a clean bill of health, why not try a longer ride with the
first check at least 12 miles into it.
