Heat forces changes in Olympic cycling rules

ATHENS, Greece -- Because of the excruciating heat under an
unrelenting sun, Olympic cycling organizers allowed team cars to
provide their riders with water during Saturday's road race.

With temperatures reaching 100 degrees on some stretches of the
8.2-mile course, organizers realized that having just one feed zone
along the circuit was insufficient, and allowed team cars to give
bottles to their riders, too.

Doctors estimated riders would need about 10 liters to drink and
cool them down during the 139.4-mile, six-hour race. Some riders
lost more than four pounds over three hours in training, despite
drinking three liters of water.
