Motocross vs Enduro vs Hare Scramble vs Desert: Explained

The names describe three things: where the course is, how long you race, and whether you race the rider next to you or the clock. Motocross, supercross and arenacross are short sprints on a built track. Hare scrambles, GNCC and grand prix are timed lap races on a loop of several miles. Enduro is raced against the clock. Hare and hound and desert racing cover real distance, from a 60-mile minimum up to 964.66 miles for the 2026 SCORE Baja 1000.

Our own ground is desert racing: the Mint 400 and Vegas to Reno with Best in the Desert, the Baja 250 with SCORE, and the Parker Dam 500 and Baja Nevada with Legacy Racing. Our riders also race WORCS, NGPC, NSRA, hare scrambles and pro motocross, so between the three of us we have lined up for most of what is on this page.

What is motocross?

Motocross is the base that most of the others borrow from. The AMA rulebook describes a closed course with left and right turns, hills, jumps and irregular terrain, in general between half a mile and a mile and a half long. Everyone in the class starts together behind a gate.

At the top, the Pro Motocross Championship is 11 rounds, sanctioned by AMA Pro Racing and managed by MX Sports Pro Racing. Each class races two motos of 30 minutes plus two laps, and the points from both motos are added to decide the overall. Amateur motos are shorter. At the AMA Amateur National at Loretta Lynn’s, the biggest amateur race in the country, every class runs three motos, and MX Sports lists most of them at 20 minutes, with 15 minutes for the youngest, oldest and C classes and 25 for the Pro Sport classes.

The bike is a 250 or 450 motocross bike: stiff suspension, close-ratio gearbox, small tank, no lights. Brock runs select pro motocross rounds on our team, including Pala, Thunder Valley and Washougal.

What is supercross, and how is it different from motocross?

Supercross is motocross moved indoors. Supercross 101 puts it simply: motocross uses the terrain nature offers, and supercross tracks are made from dirt hauled into stadiums. The jumps are bigger and closer together and there is very little room to rest.

The night is built to cut the field down. The fastest 40 riders in each class from qualifying race two heats of six minutes plus one lap, then a last chance qualifier of five minutes plus one lap, to fill a 22-rider gate. The main event is 20 minutes plus one lap for the 450 class and 15 minutes plus one lap for the 250 class. Triple Crown rounds replace that with three shorter mains per class, 12 minutes plus one lap for 450s and 10 plus one for 250s, scored so the lowest total wins.

Monster Energy Supercross is an AMA championship. The 450 class races 17 rounds from January to May, and it starts in Anaheim.

What is arenacross?

Arenacross is the same idea on a smaller floor. The AMA rulebook defines it as racing in an arena on a manufactured track with a heat and final program, and defines supercross as the same thing “typically on a larger scale.” The AMA calls the tracks tight and technical.

As of the 2026-2027 season the AMA Arenacross Championship is two regional series totalling 28 rounds, plus a playoff finale. It has classes for amateurs and kids as well as pros, so it is one of the few ways a regular racer gets to ride a stadium-style track in front of a crowd. I could not find main event lengths published on the series site, so I have left them out of the table.

What is enduro?

Enduro is where the names start to confuse people, because nobody races wheel to wheel. The AMA describes difficult test sections linked by fire roads, jeep trails or two-track, with small groups of riders, generally three to five, flagged off at one-minute intervals and scored at checkpoints.

There are three versions:

• Timekeeping (traditional) enduro. You hold a set schedule. The AMA rulebook calls it a meet “in which speed is not the determining factor and a time schedule must be maintained,” and you are penalised for reaching a check early or late.
• Start-control (restart) enduro. You are only penalised for being late, so in practice you ride each test as fast as you can and regroup before the next one. A National Enduro has to be at least 65 ground miles under the AMA rulebook.
• Sprint enduro. No transfer sections at all. The US Sprint Enduro Series uses two courses, a grass-track cross test and a woods enduro test. Riders leave one at a time, ride at least six tests a day over a two-day round, and the lowest total time wins. The AMA rulebook sets each sprint test at 2.5 to 15 miles and the event at six to 12 tests.

The bike is an off-road enduro model: softer suspension, wide-ratio gearbox, bigger tank, 18-inch rear wheel.

What is a hare scramble?

A hare scramble is a lap race on natural terrain. The AMA describes it as riders in a class starting on the same row and racing all-out on a marked course of several miles through woods or desert, until the leader completes a set number of laps or a set time, “usually two hours.” The rulebook allows a course anywhere from 2.5 to 40 miles long.

Whoever has the most laps wins, and ties on laps go to whoever crossed the line first. The AMA runs East and West Hare Scrambles championships, with the West series in California and Nevada. Justin races the Western Hare Scramble series on our team.

What is GNCC, or cross-country racing?

GNCC stands for Grand National Cross Country, and “cross country” is just another name for hare scrambles. GNCC is the national series, sanctioned by the AMA and produced by Racer Productions.

What sets it apart is length. The GNCC FAQ lists a 10 to 13 mile course for bikes, 90 minutes for youth bikes, two hours for the morning bike race and three hours for the afternoon race where the pros run. Starts are dead engine, one row at a time, a minute apart. Snowshoe in West Virginia and the Ironman in Indiana are the two rounds most riders name first.

The bike is a cross-country model, which is close to a motocross bike with an 18-inch rear wheel, a larger tank, a kickstand and softer suspension.

What is a grand prix (WORCS and NGPC)?

A grand prix is the western answer to the hare scramble: part motocross track, part off-road. Under the AMA rulebook the course must include a motocross section, a natural terrain section and a grass track, graded or asphalt section, each loop is 2 to 12 miles, and the race runs between 30 minutes and two hours.

The two big series are close cousins:

• NGPC, the AMA National Grand Prix Championship. Its supplemental rules require a track of at least three miles. Most classes race 40 to 50 minutes, youth classes 25 to 30, and the pro and top A classes a minimum of 90 minutes. Starts are dead engine, in waves 10 to 30 seconds apart.
• WORCS. Its rules page gives race lengths from 30 minutes for youth classes up to 120 minutes for the pro classes, on courses of 3 to 10 miles that use both the motocross track and the off-road course.

Scoring is the same as a hare scramble: most laps, then fastest. All three of us have raced these series, and there is a full walk-through in how to race WORCS, NGPC and District 37.

What is a hare and hound?

A hare and hound is desert racing with a mass start. The AMA rulebook defines a marked natural-terrain course run point to point or on at least two loops, with most of each loop used only once, each loop at least 30 miles, and at least 60 miles in total. Unlike an enduro there is no time schedule. The order riders cross the finish line is the result.

The start is the famous part. Everyone lines up side by side with engines off and races across open desert to where the trail begins. The rulebook requires that bomb run to be at least 500 meters long. In the AMA National Hare and Hound Championship, run by the National Hare and Hound Association, the course is about 70 to 100 miles with gas pits no more than 40 miles apart.

So the short version of hare scramble versus hare and hound: a scramble repeats a short loop, a hare and hound covers new ground almost the whole way.

What is desert racing (Best in the Desert, SCORE Baja, Legacy)?

This is what our team does. Desert races are longer again, bikes share the event with cars, trucks and UTVs, and the organizers sanction their own races rather than the AMA. Riders start one at a time and are scored on elapsed time, so the winner is whoever covers the course fastest, not whoever arrives first. Most motorcycle entries are teams who hand the bike over at pits, with Ironman classes for riders who do it alone.

• Best in the Desert has been running since 1984, which it calls the longest-running desert series in North America. Its Vegas to Reno is the longest off-road race in the United States. Cycle News reported the 2025 course at 498 miles, won overall by a three-rider motorcycle team in 8 hours, 2 minutes and 11 seconds at an average of 62 mph. The Mint 400 in Las Vegas is the best-known desert race in the country.
• SCORE International runs four races a year on the Baja peninsula. The 2026 SCORE Baja 1000 is a 964.66-mile loop from San Jose del Cabo with a 40-hour limit to be an official finisher. The shortest SCORE round is the San Felipe 250, which SCORE listed at 262.80 miles in 2023.
• Legacy Racing is based in Las Vegas. Its Parker Dam 500 in Arizona is a 120-mile loop that Legacy says most teams run three times, and its Baja Nevada is a multi-day race across Nevada.

The bike is a 450 set up for speed and range: a large tank, steering damper, tougher wheels and, for races that run into the dark, lights. We race the Honda CRF450X. Our dates are on the schedule.

What are hard enduro and EnduroCross?

Hard enduro is the opposite end from the desert: very slow, very technical. The AMA rulebook defines it as an event made of obstacles that take a high level of technical skill, on at least 50 percent natural terrain, getting harder as it goes. The AMA lists near-vertical climbs and descents, boulder-filled rock gardens and log crossings.

The marquee US race is the Red Bull Tennessee Knockout, the final round of the AMA National Hard Enduro Championship in 2026. It runs over three days in knockout rounds, with more than 540 entries cut down to the 20 riders who make Sunday’s main event.

EnduroCross takes those obstacles indoors. The AMA EnduroCross Championship is six rounds in arenas in 2026. Amateur classes race a qualifier and a main of four minutes plus one lap, and the pros race three motos of six minutes plus one lap each. Six minutes sounds short until you watch a rock pile at race pace.

Which should you try first?

Pick by what is close to home and what your bike already suits.

• You have a motocross bike and a local track: race motocross. Practice days are easy to find and the motos are short.
• You have a trail or cross-country bike: enter a hare scramble or a grand prix. You get 40 minutes or more of racing for one entry, classes are split by skill, and big jumps are usually avoidable.
• You like the idea of racing the clock rather than a pack: try a sprint enduro. You start alone, so nobody is on your rear wheel.
• You live in the West and want open desert: a hare and hound is the step before the long races. You need to be able to ride 60 miles or more at pace and manage fuel.
• Long-distance desert, supercross and hard enduro: work up to them. They punish mistakes harder than the others.

Whatever you choose, almost every series on this page asks for an AMA membership or its own series membership before you can enter. The step-by-step is in our guide on how to start racing dirt bikes.
