Definitely one of my favorite VR routes. Incredibly challenging, but breathtaking scenery.
Mt. Rushmore Half Marathon runner
Definitely a highlight so far this year
Standing in the middle of nowhere at 5 AM with almost 2000 other runners, watching the sky turn pink and waiting for this run to start, was definitely a highlight so far this year. Hope to do it again.
