From the Organizer

 

One of the most scenic and challenging 1/2 marathon and 10k courses in Arizona! This challenging course is located in the scenic and cool Ponderosa Pine forest of Groom Creek just 5 miles South of Prescott. The 5k and fun run courses stay on smooth pavement with rolling hills. The 10k and 1/2 marathon courses begin and end on pavement, but also wind through the forest on smooth, wide dirt forest roads.

 

  • Race is limited to 100 half marathon spots, 60 10k spots, and 100 5k spots.  Don't wait!

  • We will have a cupless course.  This means that we will not have paper or plastic cups at the water stations on the course.  This is in an effort to reduce litter in our forest, and reduce the one-time use of paper and plastic cups.  All runners will be given a reusable and foldable hydration bottle at registration.  Alternatively, you can wear any hydration pack that works for you!  We WILL offer cups at the start/finish line stations.  There WILL be water stations throughout the course where you can fill your bottle or hydration pack.

  • Bring your own swag bag.  Runners will receive an even shirt and hydration bottle.  Along with our efforts to curb waste, we will not be handing out bags to all runners.  These plastic bags traditionally are tossed in the garbage once the runners get home.  We want to reduce this kind of waste. Should you absolutely need a bag, there will be small plastic garbage bags available on request.  We will again be providing free bag check.

SWAG AND AWARDS

  • All runners receive an event T-shirt with entry. 
  • All runners receive a foldable hydration bottle.
  • Finisher medal for all 1/2 Marathon runners.
  • Medals for top 3 finishers in age groups (1/2M, 10K, 5K).

Race Location

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

From 5K to marathon, running races are the most accessible entry point into endurance sport. There's a distance for every fitness level and a community at every start line.
