In Phoenix for a business meeting, I decided to skip my regular morning run and hike instead. Best decision!! Get up *early* and arrive 15-30 minutes before official sunrise. Cholla trail took me 1:45 start to finish. I'm a triathlete and marathoner and moved at a solid walk, not running or really hustling. Wear a hat, sunglasses, and bring 1-2 bottles of water. You can do it in sneakers, no hiking shoes or special gear needed. Street parking is about a half mile from the trailhead so add that time to your schedule.
