I started my hike at 2:00pm and got backl to the car at 7:30pm. I hiked most of the day and ran for about an hour. It was a gorgeous day with perfect temperatures for a long hike. I watched part of the Sunset on Hawk Hill and finished it on Lower Hawk Hill. This was close to the longest hike I have done in the Marin Headlands. I got back to the car after dark and then decided to shed the backpack and do the last two peaks (Peak 197 and Peak 360) after dark with a headlight on. This completes my 50 Peak Challenge and I really appreciate the effort that was put in to getting this challenge set up. It was one of the coolest things I have done.
