For you statistically inclined, 8 miles of it (26%) is on segments of the 100 mile course, and the total vertical is about 5,600′.
So that sounds pretty challenging but really that is what is all about. Challenging the body to do something that it might not have ever done. Just two years ago I ran the Boston Marathon and I remember saying when asked “Would you ever run more than 26.2 miles ?” and my answer was short and simple “No WAY”. Wow, how things change. The endurance gene in me now has a thirst for going longer and finding things that will challenge me.
