>Seems to me that part of "walking the rice paper without leaving
footprints" is doing things as optimally as possible. That may be fast,
that may be slow. But optimal is always best.
I might also respectfully add that there already IS
a perfectly good sport with minimum time limits--it's called CTR. It is
the cup of tea for many horses and riders. The beauty of endurance is that it
provides a venue for distance riding for horses whose optimal speed is either
faster OR slower than CTR.
