My wife and I are planning our Camino in late may of 2018. We are avid hikers, Grand Canyon rim to rim 4 days 3 nights in June 2 years ago. A lot o high elevation gain hikes but only day hikes. The most in 1 day 15 miles with 2500 elev gain. Back to back 12 miles 2 days in a row. She is 15 to 17 minute miles and I do 18 to 20 min mile. We are wondering if we will be able to do those miles everyday. I know and her for sure that we need to slow down. Think we can do it? Tell me what you think. By the way I am 64 and she 63 and I plan to finish at the Fenestra on my Birthday June 30th.
