What is an Enduro?

An enduro is an off-road motorcycle race that is designed to test the physical and mental endurance of the rider and motorcycle. Most enduros are 60-100 miles in length for long course riders, and 40-60 miles for short course riders. Riders must not only be skilled at riding their motorcycle, but they also must be skilled at the mental, timekeeping aspect of the race. The sport is based on riders attempting to maintain an exact schedule, regardless of the diffcult terrain and conditions they may encounter. Since an enduro is based on time, not all of the riders racing start at the same time. Riders are assigned a 'minute' or 'row' number. 4-5 riders will start on each minute after the start of the race (generally 8:00 AM) until all the riders have started. Checkpoints, where crews will mark the time of each rider's arrival, are located along the course. There will also be resets, free times, and gas stops where, if on time, a rider will have a chance to rest, drink water or grab a snack, and fuel their bike. After the race, the score of each rider is calculated. The riders with the lowest number of penalty points are awarded trophies in their respective classes. To anyone new to the sport, it can sound quite complicated, but it really is pretty simple once you race one and get the hang of it!

Basic Enduro Terms and Definitions

Key Time	The scheduled starting time and scheduled time of arrival at each checkpoint for a rider on row 00. (Row Zero)
Free Zone	Timed checkpoints, including Known Controls, cannot be located closer than 3 ground miles apart. Therefore 3 ground miles before, or 3 ground miles after a timed checkpoint can be considered "Free Zones". Similar Free Zones may apply to Gas Stops, usually with timed checks no closer than 2 miles before, or 3 miles after the Gas stop. A "Free Zone" is a distance on the race course where no checkpoints are possible.
Reset	A point along the course where the posted Mileage is advanced to some greater number. This gives a rider on schedule a rest period of the period of time it would have taken the rider to ride the mileage advanced.
Free Time	A point along the course where the Mileage remains fixed while the time is allowed to run. A rider on schedule would wait until the Free Time has run out, then he would proceed down the course. It has an effect very similar to a Reset.
Ground Mileage	The actual Mileage traveled by a rider, which is the posted Mileage minus any Resets.
Checkpoints	Checkpoints are located along the course where crews will mark the minute, and seconds if an Emergency check, that a rider enters the check. The Key Time and the Mileage for that check should be posted near the flags. The Mileage accuracy for the check location must be within 1 tenth of a mile, while the clocks used at the check must be within 5 seconds of the master Key Clock. Secret Check An unknown, timed checkpoint. Early: 2 points for the first minute, 5 points for each additional minute. Late: 1 point for each minute. Emergency Check An unknown, timed checkpoint where minutes AND seconds are recorded. Early: 2 points for the first minute, 5 points for each additional minute. Late: 1 point for each minute. Seconds: These are tie-breaker or emergency points. They are calculated by totalling the number of seconds from the 30 second mark of the rider's due minute. Known Control A timed location whose location is known to all participants. Early: Zero points for early arival. 2 points for each minute for an early departure. Late: 1 point for each minute. Observation An unknown, untimed checkpoint where no time is recorded. If a rider is more than 15 minutes early, or more than 60 minutes and 59 seconds late to any checkpoint, they are disqualified at that point and will receive credit for all checks up until that check.
