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!

About This Sport
From Endurance Grid's Founder
Endurance Grid is here to help you understand the sport, decide if it's the right fit, and learn how to prepare. For course distances, logistics, and race-day specifics, always defer to the race organizer's event page.
The half marathon is the distance where you find out what you're actually made of. Long enough to demand real preparation. Short enough that it doesn't consume your life to train for it. Most people who run their first half describe it as the race that changed their relationship with what they're capable of. Once you cross this finish line, the bar moves. That's not a warning — that's the point.
Race day energy varies by event size, but the finish line feeling is the same regardless. Big races keep the noise going the whole way. Smaller races give you stretches where it's just you and the miles — and that solitude becomes its own kind of fuel.
The half marathon rewards people who show up for the boring training miles.
How long to train: 10–14 weeks. If you're already running consistently, 10 weeks of structured buildup is enough. If you're building from a casual base, give yourself 14.
Running
