A couple of years ago, there were coyotes attacking joggers in Frisco, TX.
Sixth Coyote Attack Reported in Frisco
Just a few weeks ago, I saw one during the day on the opposite side of the DFW airport fence.
That being said, attacks on people are still really rare. If you're moving at a good pace, you probably even have less to worry about.
The best thing you can do is ride with a buddy that you're faster than.
