The hike itself to Mount Reyes is 16 miles round trip and 3500 feet in elevation and is labeled strenous. Trail is rocky in parts, but offers beautiful portions along the way and a big payoff at the end.
"So I was sitting in my cubicle today, and I realized, ever since I started working, every single day of my life has been worse than the day before it. So that means that every single day that you see me, that's on the worst day of my life."
