Thirteen holes. Not nine, not eighteen. Tucson's Preserve runs its own schedule. The desert layout forgives walking legs more than most Arizona tracks, where elevation and sun can turn a round into a survival test. At 73 on the walkability scale, this one lands in solid territory for the region. Green fees stay reasonable for what you get. The format feels like a throwback experiment that worked. Show up without expectations about how golf courses are supposed to be structured. Walk the thirteen. See if it changes how you think about round length.
