The course for the Run for Ryan House at DC Ranch Half Marathon starts and finishes at the Village at Market Street near DC Ranch, and from there runners head out through the shopping village area onto Desert Camp Drive, which they follow again out to Thompson Peak Parkway. This begins a roughly three-and-a-half mile stretch that takes runners along Thompson Peak all the way southward past the preserve to McDowell Mountain Ranch Road.
