Loved the Route for our laps, beautiful scenery, in the first 2 miles we spotted 2 white tail deer, continued along this gorgeous riverside walkway, well marked cones for the turn arounds. Best part of Mainly Marathons is all the support from fellow walkers and runners. Jesse, Daniel and the volunteers make everyone feel welcome. We had a blast!! Rubber bands concept is fun also.

I always think when I start a series they will all bee\ marathons but the truth is every runner has better days than others. I am sure you can see by my time I wasn’t fast but you can’t see that this is my time for 18 miles. The race was great I didn’t feel great. But I got out there. Keep moving my friends, always keep moving.
Worth the drive

This race was part of the Mainly Marathon Prairie Series, which is notoriously hot and frequently humid. Fortunately, this course had quite a bit of shade. The route started at the Mainly Marathon “camp” and zig-zagged through a combination park/recreational complex in Riverside Park in a short out-and-back, and then proceeded to another out-and-back underneath the freeway overpass to a pretty stretch along the Big Sioux River. The first few hundred yards of the second out-and-back was open to the sun, but the rest did have quite a bit of shade. The advantage to this double out-and-back is that you ran by the aid station about every 0.5 to 0.75 miles. This makes it easier to keep hydrated and fueled without having to wear a hydration vest or carry a hand-held bottle. I thought this course was better than the Mainly Marathon races in Nebraska and Missouri that I ran last year as it was more scenic and had a little more shade. A bonus was the sighting of several white-tailed deer, including two new-born fawns along the paved trail that went along the Big Sioux River.
