For me, at age 65, it was 9 hours from the start of crossing the dam to Mollies Ridge. 10.7 miles I think. That included a leisurely lunch and a short trip and 30 minute stay at Birch where I had contemplated staying. Too many flies there so I opted to continue to Mollies. I did the 5.3 from Birch to Mollies in about 3.5 hours.
