They were there to carry the Special Olympics torch across the entire county of San Mateo. That's almost marathon distance.
It's been a long tradition for law enforcement to carry the torch as a way to raise money for the Special Olympics. Last year, they raised more than $42 million nationwide.
The torch will pass through San Francisco on Monday. It will end its run a week from Friday in Davis -- in time for the opening ceremonies of the Northern California Special Olympics.
