This is a 2 day teams competition which consists of mountain bike agility, swim, canoe, bike relay speed retrieve from water
and run two miles up, ending atop the mountain 11 000' high where it snows in July
and then
to run back those 2 miles DOWN (this is
what kills the legs). And... on the way down the dogs had to wear packs
containing 10% of their body weight. Keen handled her 4.5lbs. just fine!!
