This exercise system originated in Sweden where trotting is a
major sport. It may well be the reason for the Swedes' supremacy
in this field as their horses are exercised from six months to
maturity by a natural and simple method that causes no ligament
or joint stress to their horses. The exercise yard consists of a
series of corridors side by side. Each one is fairly narrow - 6
to 10 yards wide and 100/200 yards long. The corridors are
separated by 2 strands of tape and closed at the ends with 3
strands. One horse is put into each corridor for 2 to 3 hours.
It is important that the horses should be beside each other.
They will tend to run up and down the full length of the
corridor out of curiosity, competitiveness to their neighbor, or
just out for playfulness. As each horse is confined to it's own
corridor it is unable to injure itself or either of it's
neighbors. When the horses stop running and playing it is either
because they have become used to their companions or because
they have exercised enough.
