Coyote attacks on people are very rare. More people are killed by errant golf balls and flying champagne corks each year than are bitten by coyotes. Source: http://www.humanesociety.org/animals/coyotes/tips/coyotes_people.html

Make yourself as large and imposing-looking as possible. This can be achieved by holding your backpack above your head or opening up your jacket.
3
Shout or yell to frighten the coyote. Keep making noise.
