Seabiscuit carried 133 lbs in three races and won all three times! He was five years old when he was given that weight. As a three year old Seabiscuit did carry only 115 to 120. He set a track record under 133 lbs. at Bay Meadows on April 16,1938 while he was giving the runner up 20 lbs.
I realy do not know what you are trying to say in this post. Seabiscuit was named for a government issue of bread. Ships in the Navy were at sea for long periods of time so they needed a bread that would not get stale in a long time, Thus a sea biscuit was invented for the US Navy.
