The Mainly Marathons events are my favorite racing events, period. They do a great job of catering to the runners and the overall organization of these events are down right awesome. I highly recommend any of their race series. This location does have a more difficult course, Although flat it is completely crushed gravel.
Social marathon; not for racing

I think that Mainly Marathon races are an acquired taste. They put on marathon series where you can do up to 5-7 marathon in 5-7 states in 5-7 days. There are no overall or age-group awards, and the courses are usually repeated short loops or short out and backs. The on-course support is without rival. Their aid stations are stocked much like many ultramarathon aid stations and serve soups, potato salad, or sandwiches, depending upon the weather. They supplied ice water at this year’s Prairie Series, which was a life saver with the hot weather that was experienced. The Day 3 course was in a small park along the Big Sioux River. There was a nice view of a short waterfall that was the former location of a mill. The course consisted of two short out-and-backs, and was a little short for my taste. It allowed for a lot of interactions with other runners as you passed them running in opposite directions. During the summer, I would highly recommend the early start if offered, as it can be very hot and humid in the Midwest in July.
