I am 67 years old and have spent the last three months preparing for something called "The Ultimate Hike"--a 30.1 mile hike in one day to raise funding and awareness for children's cancer research. I trained doing lots and lots of walking, climbing stairs, and strength training. We began hiking on Saturday at 3:30 AM in pouring rain and darkness. The path turned to slimy muddy muck. It involved endless switchbacks, hiking over narrow narrow paths with deep ravines. I was only able to walk 22.5 miles before we were pulled off the track before dark. I have discovered that although I can climb easily enough (my Fitbit said I climbed the equivalent of 426 FLIGHTS of stairs on Saturday) the descents were way above my pay grade. I have a lazy eye and have no depth vision so have a very hard time discerning space and distance. Even with hiking poles I was TERRIFIED of falling off cliffs for most of the hike. Bottom line. I think I would have no trouble with walking the distances as I was routinely walking 12-15 miles a day in training. I had hoped to keep up the training and start the French camino in the Spring. But I do not think I could face another narrow descent on a switchback. I know I will have to climb over several passes...but how treacherous are they? Would really appreciate an honest answer from someone who might be similarly challenged. ( I had been assured when I signed up for this hike that this one was not going to be challenging in that respect. My oh my they were wrong!) El Camino is the last official thing on my "bucket list". I have wanted to do it since I first read about it at the age of 7 in my big brother's 4th grade Reading Book! thanks.
