🚨 Registration for the 2025 editions of Rock Hawk and North Fork are OPEN! 🚨

Join us this spring for incredible trails, gorgeous views and amazing community.

Kick off the 2025 Bear Chase Race Series with the first race out of four, Rock Hawk. Take on a 50k, 25k, 10k or 5k held on the gorgeous, thrilling and rolling trails of Castle Rock’s Miller Park & Ridgeline Trail systems. While not overly technical, these trails will challenge and excite, as you soak up amazing views! An excellent race for both first-time and veteran trail runners, Rock Hawk is the perfect first race in the Bear Chase Series, and provides a nice test for those who are training for longer summer events.
Rock the Hawk then join us the following month in Buffalo Creek on May 31st for North Fork 50 mile/50k! This small capacity gem of an ultra marathon takes place on 100% soft surface, made up almost entirely of incredible singletrack trails with a few short sections of double track road.

Climb through open burn areas from a 1996 fire, then dive back into the beautiful ponderosa pines and wind around towering granite rock formations as you excite your senses and challenge your mettle! And as always, along with beautiful scenery and amazing trails and community, expect the welcoming, inclusive and high energy party that Aravaipa Running is known for.
