The July Idaho Falls Half Marathon 2021 in Idaho Falls, ID is a point to point course running through the valley of the Grand Tetons, starting in the Rocky Mountain foothills and finishing along the banks of the Snake River. The course is noted to be a fairly fast course, however I did catch a glimpse of one big uphill in a race photo, hence the course is not all downhill and flat. No course elevation gain or loss is shared by the event. Post race breakfast is provided for participants at the finish line, with an assortment of breakfast foods, which is always a great bonus! The half marathon is walker friendly.
