Olympic gold medalist (rowing, 1984) writes a bunch of books. Then goes hiking, specifically the John Muir Trail. I've hiked the length of the JMT (223 miles) 27 times over the last 35 years. Solo. Better that way. You can go slow or go fast. Stop when you want. Eat when you want. Sleep late or get up at 1:30 AM and hit the trail. Who's to say no?
Maybe I'll see you one the trail next summer? Hope so.
