I joined a 6 a.m. hike up Pinnacle Peak, a local landmark popular with hikers and demon athletes who walk or run the hill. The full hike is 3.5 miles round trip, with a total elevation gain of 1,300 feet (2,889 feet is the highest point on the trail). Tack on 2 miles roundtrip to get there, and I had a nice bit of exercise before the heat really started boiling.
