It is 250 feet total, so 125 feet out and 125 feet
back.

From the
control judge handbook:
The Cardiac Recovery Index: The
ability of the horse's circulatory system to accommodate the level of exertion
experienced at the event is monitored by use of the Cardiac Recovery Index
(CRI). The CRI may be performed at all control checkpoints at endurance
rides, including the finish line control check. The horse is not presented until
it has met recovery criteria established for that ride, usually of 64 bpm or
less. The horse is then presented to the control judge, and a resting heart rate
is taken. Then the horse is trotted 125 feet out and 125 feet
back. (The gait can be observed during the jog out for soundness and
impulsion.) At exactly one minute from the time the horse started the 250
foot trot out, the heart rate is taken again. Most horses complete the trot
out within 25-30 seconds, allowing the horse to stand quietly for the remainder
of the minute. (For a horse that does not object to being handled, the
control judge can initiate evaluation of the metabolic parameters during the
remainder of the minute.) A horse that is demonstrating adequate metabolic
compensation should recover to the same resting heart rate taken before
the 250 foot trot out, or preferably to a heart rate of four
bpm less than the starting rate. If the heart rate elevates during the
CRI, the horse should be asked to return for a recheck CRI within 10-15
minutes to monitor for progressive recovery. The control judge should take a
second look at all metabolic parameters at that time, including a second CRI.
The CRI is not necessarily used to eliminate a horse from competition; the
entire clinical picture is used to assess the ability of a horse to continue
in the event.

Can anyone tell
me, the total feet in the out and back on the CRI trot out? I'm tired
of being winded after the end of my CRI trot out, so I'm going to measure off a
section of my driveway and work on running so I can get better. Ride
Management never seems to have an Oxygen tank around when I need
one!
