From the Organizer
Welcome to Adventure Racing! The Greenhorn AR, now in our 11th edition, was created to offer competitors a gateway into the sport of adventure racing. This 4 hour sprint adventure race was designed with the beginner in mind, but fun for everyone no matter the skill or experience level! While there is significant challenge built in, this event is fun and highly achievable for the novice racer. The navigation is straight forward and the maps that we provide are excellent. The mountain biking takes racers over gravel roads, some pavement, and semi-technical singletrack trails. Finally, the paddling takes place on a clear lake.

From Endurance Grid
Endurance Grid is here to help you understand the sport, decide if it’s the right fit, and learn how to prepare. For course distances, logistics, and race-day specifics, always defer to the race organizer’s event page.
Adventure racing strings together trekking, mountain biking, and paddling — with navigation by map and compass — across a course you have to find as much as finish. Most events are raced as a team, often over many hours or even multiple days.
It rewards the all-rounder and the problem-solver as much as the pure athlete: route choice, teamwork, and staying steady when you're tired and off the map are as much the challenge as the miles.
Trek, mountain bike, and paddle with navigation between checkpoints — from a few hours to multi-day expeditions, usually in teams.
