Natural light began to take over shortly after reaching the summit of that climb, so the rest of the trip on the AT was business as usual - tripping over rocks, turning ankles and exchanging comments with other runners with virtually no one else around.
I reached the towpath at about 8:35 a.m., only five minutes slower than I had planned, ready to take on the mentally challenging portion of the journey.
With the Potomac River on the left and the waterless C&O Canal on the right, this 26-mile segment is normally void of visual stimulation.
But this year was different. From beginning to end, the stunning fall foliage, still clinging to their branches, reminded me why some people find this area so beautiful. The view across the rippling waters of the Potomac and the canopy of leaves over the canal were simply breathtaking.
I felt more energized on the towpath this year than I recall feeling in the past, and the colors likely had something to do with that.
In the past, I started the race well behind the leaders, stayed well behind the leaders and finished well behind the leaders. Starting two hours earlier, however, the leaders started passing me on the towpath - like speeding cars on an interstate highway. And I still finished well behind the leaders.
Meanwhile, I shuffled along, focused solely on finishing. What struck me, though, were the number of frontrunners who provided words of encouragement as they sped past: "Keep going" or "You're looking good" made a big difference for me. They didn't have to say anything.
For years I've had a love-hate relationship with the roads from Dam 4 to Williamsport. Traveling that stretch after dark is normally the coldest part of the race. This year, I finished during the day.
So, I reached the final aid station with about 14 minutes to go to set a personal best time. Should I try to run the rest of the way in, or gather some fuel and be happy about finishing with a satisfying time? That decision might be my only regret of the day. I missed a personal best by less than three minutes, but I finished.
Finally, I would be remiss if I failed to mention this one constant - from Gathland State Park to the bottom of the switchbacks at Weverton, all along the towpath and certainly at the finish line - the applause and words of encouragement from the people who volunteer at the aid stations, show up to assist other runners or simply watch is, as MasterCard would say: Priceless.
