To create some distinction as far as how long it takes to run most of the trails, RZR's that are well built can knock it out about 2-3x as fast, maybe more on some of the rougher ones. We did PS, Gold spike and gold bar with stopping at the crack and eating and other running around, taking pics, taking optional lines, etc in 4 hours truck to truck (we staged the tow vehicles at Gemini bridges drive and started at PS.) My buddy in a built LJ on rock jocks and 37's took 10 hours to do the same loop. We ran all the trails in the "hard" side of the book in 4 days, and were done early and at the brewery most days. Excited to go back
