The source text doesn't have enough usable detail about Big Woody Rides specifically to say anything honest beyond this: it's an Aravaipa Rides event, and if you know Aravaipa from their running roots, you know they build things to be fun, inclusive, and worth the drive — sufferworthy but never exclusionary.
Distance options include a 36-mile Solo or Duo, an 18-mile Solo, and a 13-mile Solo, so there's a real on-ramp here regardless of where you're at fitness-wise.
