23nd Annual Groom Creek Classic: 1/2 Marathon, 10k, 5k Run – Prescott, AZ 2026

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
