This was by far the toughest 50K I have ever done. Over 6,400 feet total elevation gain with a peak elevation of 10,400 feet. There will still patches of snow above the Pajarito Ski Area the week of the race. At the summit, we had a great view of the Valles Caldera, a crater from an ancient volcano. The course would have been more scenic, but fires swept through some parts of the course in recent years and wiped out the trees. Epic but difficult course.
