One of his favorite routes starts at the base of Flagstaff Mountain (an elevation of 5,300 feet) and trails up to the 8,144-foot summit of Green Mountain. He then makes his way back down through trails, single-track dirt paths, and paved roads.
“That’s about a 12-mile run with 3,000 feet of vertical gain — at high altitude — and it takes about two hours, depending on how I run it,” Robert explained in a chat with Spartan. “For me it’s about training for the distance instead of training for time, because you race the distance, you don’t race time.”
He’s a dedicated father-of-two.
