Should I sign up for the 5K or the Half Marathon?

You have several options: a 1-mile fun run, 5K, 10K, and 13.1-mile Half Marathon. Because the event uses wave starts (7:30 AM, 8:00 AM, and 8:30 AM), I recommend the Half Marathon if you want more solitude on the course, or the 5K if you want to be part of the immediate energy of the crowd. Keep in mind that since there is no official chip timing, your "race" is really a self-timed effort on your GPS watch.

What should I expect from the terrain?

The course is set within Piney Creek Hollow Park, which means you'll be on paved park trails and connecting pathways. Expect a non-technical, accessible route that is mostly flat with some gentle, rolling suburban undulations. It’s perfect for beginners or anyone who wants to avoid the mental tax of technical trail running.

Is it going to be a heatwave on race morning?

June in Colorado can be unpredictable. While the early wave starts (7:30 AM) help you beat the worst of the afternoon sun, Centennial can quickly climb into the 80s (F) by mid-morning. Bring lightweight, moisture-wicking gear and don't skip the hydration. The high altitude of the Denver area also means the air is dry, so you'll dehydrate faster than you realize.

How much am I going to pay to run?

The pricing is remarkably fair for the Colorado running scene. A 5K is $40.22, a 10K is $45.52, and the Half Marathon is $48.70. If you are running multiple distances, there is a 10% bundle discount available. For the price of a single premium race entry elsewhere, you can essentially cover almost any distance here.

What do I get for my registration fee?

You aren't just paying for the miles. All participants receive a finisher medal, a running T-shirt (shipped to you if you are in the US), and a finisher towel or giveaway. You also get access to a digital training pack and online results to log your effort. Check Run Signup ↗ for the full breakdown of swag.
