>The race tracks adjust this weight
in a few pounds extra when they race at the tracks over relatively short
distances, never mind over huge distances and obstacles night and
day.
The race tracks also run anaerobic events. The
ability to carry weight under anaerobic conditions is about 1/20th of the
ability to carry it aerobically. So the differences between each
of our weight divisions are about like a 1-lb difference at the
track.
