It is exciting to bring you another exquisite day of racing alongside the scenic Arkansas River! This is a fast course that starts in Pueblo's City Park then you quickly drop down to the scenic river trail, where you will be encompassed with nonstop gorgeous terrain and scenery. This smooth path will lead you along the river with kayakers and wildlife galore. You will hit some dirt trails as you head west to our Nature Center and then swoop around the corner to an open field where deer are usually always in sight. You will then head back along the trail and hopefully with fast footing and well refreshed as there are several water/gatorade stations along the way. Make sure to give a big "hello" to our high-school and club runners at the aid stations!
Every year this race gets a host of runners going for their first 13.1 goals, return racers that have made this race a tradition year after year, and showcases many elite trail and road racers. The array of accomplishing racers have been a joy to see as they take on this fast course and come through the finish line!
We are ready to cheer you all!
