The Poly Canyon trail run is an eight mile loop that begins and ends at Cal Poly. The challenging, enjoyable run traverses grassy farmlands and features a few moderately steep hills . There is little shade during the middle of the day, so it's best to go in the morning or evening. Be sure to watch out for cows and mountain bikers, who tend to roam free with little regard for the established trail.

Trailhead: Begins on Poly Canyon Rd, which is off Village Dr.

Difficulty: Hard

Time: Depending on speed, about an hour
