With an extreme heat advisory forecasted, the race director made the decision the day before to allow an optional, extra early start at 3:30 a.m. I accepted this offer gladly, and was so glad I did. The course was along a concrete path alongside the Missouri River. About a 1/4 mile from the start, the path went right by a casino. Due to the heat, the race director shortened the course and placed aid stations at both ends of the out and back so we would never be more than about 3/4 of a mile from fluids and ice. It worked well, and I was able to follow through with my plan to opt in to the 50K distance that is offered with each of their marathons. Shade became rather scarce near the end of my run, but there was a slight breeze blowing up the river that helped a little. Menu items at the aid station included berry smoothies, potato salad, and hot dogs, along with the usual ultramarathon fare. These races are a little bit expensive, but you get a lot of support for your money.
