2025 BILTWELL 100

The annual Biltwell 100 will take place April 5-6 2025, with a full two days of racing!

Full event schedule to be released soon.

The Start/Finish area is in the Football Field OHV area off the 395 just south of Ridgecrest. All rider’s meetings, awards presentations, vendors, etc will be at the stage area right off Dirt Diggers Road (same spot as the previous years) Here’s a map, but keep in mind, sometimes Google or Apple freaks out, so keep an eye out for Dirt Diggers Road off the 395, turn East on that and you’ll see all the vehicles and pits set up about 1/4 mile in - and use this rough course map as an extra reference.

The town of Ridgecrest is 10 miles north and has just about any sort of supplies you might need. And Randsburg is a great little hippy ghost town about 12 miles south, with bars, restaurants, etc.

GENERAL INFO

We’ve divided the vintage classes based on era/style of bike and rider skill level as usual. Men and Women in the same class (Dual Shock Novice for example) will generally start at the same time but will be scored separately.

The Modern classes are determined by age group. Men and Women in the same class (Modern 18-40 Novice for example) will start at the same time but are scored separately.

ADV Lite and Heavy classes are meant to include riders on adventure bikes that didn’t fit neatly into previous classes. Men and Women in the same class (ADV Lite Novice for example) will start at the same time but are scored separately.

Thanks to Mike Davis for organizing the Early Iron class for 1960 and earlier American Motorcycles. This is a combined class where men and women are scored the same. An even tougher version has been added now – Early Iron Endurance which is the same rules but is twice as long – two laps!

Pull-start minis get their own class since this is SO competitive now! Pull-start engines can be any size as long as they are only started with a pull-rope mechanism.

Any Harley over 750CC is in the Hooligan class and only racing other Harleys.

All classes get a trophy for 1st, 2nd and 3rd. Total number of entries is capped at around 350 racers. This event will sell out, so once we open registration you should go for it. Watch Biltwell social media for more last minute updates.

CLASS NOTES

• No class changes will be permitted at registration.
• Racers may enter only one class.
• No “team” riding. One rider, one bike, per entry.
• Classes may be mixed at starting line but will be scored separately.
• The fastest classes will start first. Men and women in the same classes may start together but will be scored separately. Different classes may be combined to create a full row but racers will only be scored against riders in their own class. There will be a short break between each starting row.
• A single lap is roughly 25 miles. Classes run between 1 and 4 laps depending on age of bike and rider.

CAMP

Camping is “dispersed” and free of charge. This area is BLM land, so all the usual rules apply and we expect you to leave it cleaner than you found it.

If you are not actively pitting for a racer, please camp on the North (left) side of Dirt Diggers Road. There is way more room there and it’s also less dusty and a lot better spot to spectate once the race starts. 

SPECTATE

The Start-Finish area is easily accessible off HWY 395 and is no problem for choppers, motorhomes or non-4×4 vehicles.

Make sure to stay out of the “Live Pit” areas and at least 150’ from the race course at all times. Otherwise, spectating can be done anywhere along the race course and surrounding areas as long as that 150’ distance is maintained. Bring a dirt bike, quad, side-by-side or buggy and enjoy the trails before, during and after the race.

There will be a party in the Start/Finish area with trophies, etc on Saturday night. More details to come.

PLEASE PICK UP YOUR TRASH. 

We’ve got plenty of dumpsters and port-a-poties, but can always use your help keeping the desert cleaner than we found it!

RACE NUMBERS

These will be handed out at registration and are really nice pre-printed graphics for each side and front number plate on any bike. Numbers are assigned randomly to speed up the registration process.

STARTING ORDER

Everyone in a class lines up and starts at the same time. Example: Modern 18-40 Expert class includes both men and women. They will all start at the same time but will be scored only against their own gender. Some classes may have two or more rows. It is a “rubber band” start.

PIT AREA

The pit area is open for parking to active racing participants and their crews only. Racers may camp in the pits. Spectators are encouraged to find a spot out in the hills and watch the race action! Everyone is required to stay 150 feet from the race course. Camping is “dispersed” and free of charge. Please park and camp on the north side of Dirt Diggers road. Check our rough course map for more info. Make sure to pick up your trash and any other trash you may discover while in the desert. We have plenty of dumpster capacity to help facilitate this.

RACE COURSE

We will update this section with more details after we have marked the 2025 race course.

All course markings will be traditional arrows on stakes and construction ribbon tied on bushes. You will rarely be out of site of a piece of ribbon or a marker. We do not issue GPS or roll chart maps. You can watch the 2024 race video to get a general idea of the terrain below.

RECOVERY

If you break down, please call 951-699-1500 extension 138. This will go to our command center set up at the pits - we'll then send dispatch to extract you and keep track of all downed riders in one central location. If you don’t have cell service or want an extra layer of communication, fill out the “Stuck Stub” provided in your registration packet and hand that to the next rider who passes you. If someone hands you one of these “Stuck Stubs” it is your responsibility to turn this in at the next check point or at the finish line. Realize it may take a while to get to you, so find some shade and dig into that snack and water that you so thoughtfully had in your pack. 

STAY WITH YOUR MOTORCYCLE, NEAR, BUT NOT ON THE COURSE! All motorcycles recovered on course without riders or separately from a rider will be placed near the First Aid tent in the Registration/Stage area AKA the "DROP ZONE".

SAFETY IS PARAMOUNT

Riding a motorcycle as fast as you can in off-road terrain is inherently dangerous, especially once you start to show fatigue.

When deciding on the limits of your own personal risk-management, consider stacking a few things in your favor. Since this race never gets too far from the pits, it’s easy to be complacent and think you don’t need to be prepared– you still do. You are one broken chain or collarbone away from spending a long afternoon in the desert sun, making things worse. Ironically, the majority of riders we stopped for last year with broken bikes, standing in the sun with no water were on modern dirt bikes. Just because you have a fancy bike doesn’t mean you aren’t gonna crash it or that it can’t break down!

Read below for a couple desert survival tips you may want to consider.

WEAR A LIGHT HYDRATION PACK THAT INCLUDES:

• Water (of course) as much as you can carry
• Hat
• Snack bar or two
• Cell phone, fully charged
• Basic tools, though these might be better in a hip sack or mounted to the bike
• First aid kit for yourself or others. Make sure to include a sling or cravat for isolating a shoulder/arm. You don’t really need bandaids and most of the junk that comes in over the counter kits
• Bill is a pyscho and also brings a small orange tarp for shade, or improvised stretcher, marking his position, etc. (Military guys, think VS-17 panel)

WHAT TO DO IF YOU BREAK DOWN:

• Immediately push your bike out of the way of other racers if possible, but stay next to the course
• Work on your bike in the safest possible spot, ie: not on the outside of a turn or top of a blind hill
• If you can not get it going, hand your “stuck stub” to the next rider who comes along and they will hand it in at the next check point. Make sure to write in what mile marker you passed last, name and bike number (bring a sharpie!).
• Stay with your bike, do not try to walk out. If you leave in some other way, leave a note on your bike and call the rescue number on your fender card with an update so we are not looking all over the desert for you!
• Call the phone number that will be printed on your fender card and given to you at registration. Most of the course has cell service, so this is a modern addition to the “stuck stub”. We have a dedicated dispatcher who’s only job during the race will be logging downed riders, keeping track of where they are and sending crews out to help or recover. This will be the first time we’ve used this method, so have a little patience. Last year, we had everyone back to camp long before dark and this year should be faster and more accurate.
• While you wait, hydrate, rest, have a smoke, whatever. Try to hide from the sun and wave riders by if you don’t need assistance so 100 people don’t waste time stopping for you. A simple thumbs up or “OK” sign generally works.
• All motorcycles recovered on course without riders or separately from a rider will be placed near the First Aid tent in the Registration/Stage area AKA the "DROP ZONE".
