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.

I just wanted to send a note about the pacer for 3:30. She was fanatic. She was energetic, positive, and even stayed at the finish line to congratulate incoming runners. I done a lot of races but I have never seen a pacer go WAY beyond just pacing! She deserves a medal😊

Beautifully challenging course

Fun race, beautifully challenging course on an ideal day for running. The finish area on the East Glacier Hotel lawn was great. Well done to all organizers and volunteers.
