Trail races
Point-to-point through the woods. Know the lines or follow taillights.

NPCs, not menus
Work and racing find you out in the world. Talk to people, build a reputation, and get invited to the stuff that isn't advertised.
What's on
Point-to-point through the woods. Know the lines or follow taillights.
Groomed tracks with gates, whoops and a crowd that keeps score.
One shot up the chute. Traction, nerve, and a spotter at the top.
Straight-line pits. Big tires, big spray, big chance of a winch.
Long days, checkpoints, fuel management and repairs on the trail.
Haul parts, machines and supplies across the county on a clock.
Winch a stuck rig out of a hole before dark or before the tide of rain.
Jumps, gaps and drops set up by locals who've clearly done worse.
Word of mouth, night only, no rules and money on the line.
Reputation
Favors, farm work and gate keys to land nobody else can cross.
Trail crews and race organizers who put your name on the entry list.
Underground promoters who only call once you've proven you can hold a line.
