Well, lots of things. First, visit www.velopigs.org and read & sign the Release of Liability form located under the “Our Rides” tab. All participants are required to sign before joining our rides or events.
No Sign = No Ride. Other than that: be physically fit and healthy to ride, own a bicycle or six, have experience riding gravel roads (sometimes bumpy, messy, and wet/muddy), be comfortable riding with others nearby, be comfortable having vehicles pass, assemble a packable tool and a tire repair kit (more on that below), and put on a smile.
