Marathon & Half-Marathon Course

Beginning at the start line in the Rec Center parking lot, athletes will leave the parking lot and turn left on to McDonald Rd. In just a few feet, the street will curve, becoming Leota Street. You will run west on Leota St. for approximately one half mile. You will merge left onto Buffalo Bill Trail, which is paved trail.

Running south, you will continue to the end of Buffalo Bill Trail and turn left on State Farm Rd. This short section is NOT trail, but the side of State Farm Rd. A running lane will be coned off, but please be aware the road is open. Near Echo Drive, you will be directed to cross State Farm Rd to the south and get on State Farm Trail. This is a paved and asphalt section. Your route will continue on the trail alongside State Farm Rd. You will turn into the University of Nebraska Research Center or “State Farm” at Tree Lane. The course then turns east at the end of Tree Lane in the farm and passes through a tunnel under Highway 83. You will emerge from the tunnel and immediately turn left (north) and continue to follow the paved State Farm Trail to its end. You will be directed to cross State Farm Rd to the trailhead for the NPPD Trail.

This section of trail is gravel. You will cross Walker Rd where the trail once again becomes paved. You will continue north to Iron Horse Park and its lovely little lake, where you will merge onto an asphalt section of trail. The turn-around will be located on this path, 6.55 miles from the start. Athletes will return, following the same route.

Marathon runners will repeat the same out-and-back route a second time. Our double out-and-back route has been designed to keep the half and full marathoners closer together. With our long time limit, our participants could find themselves alone for long stretches, and like our previous route, using “tentacles,” the route will keep athletes more engaged with each other and our volunteers. Cheerleaders give us courage! The route will also be spectator-friendly.

There will be aid stations every 1-1.5 miles. Half-marathoners will visit each aid station twice, with the exception of the turnaround; full marathoners will see stations four times, and the turnaround twice. The route also allows for more frequent opportunities at the port-a-potties.


5K Course

Beginning at the start line in the Rec Center parking lot, athletes will leave the parking lot and turn left on to McDonald Rd. In just a few feet, you will be directed on to the trailhead for Centennial Trail. This is a fully paved trail. This section of trail is very picturesque, running alongside the winding South Platte River. You will continue to follow the trail as it crosses over the South Platte River bridge, looping under Highway 83, all the way to its end near the Lincoln County Visitors Bureau Welcome Center. You will turn around at the Welcome Center and return to the finish line at the Rec Center. There will be one aid station at the turnaround.
