Dirty Kanza Gravel Bike Race

What is it?

A 20, 50, 100 or 200-mile-long gravel road bicycling challenge
through the Flint Hills region of east-central Kansas.

The event will start in front of the historic Granada Theater, 807 Commercial St., in downtown Emporia, Kansas. Participants will leave the starting line under police escort at 6:00 am.

100 and 200 mile finishers get a pint or half pint glass as a prize for finishing.

Each participant is considered to be on a private excursion and remains solely responsible for any accidents in which he or she may be involved. No responsibility can be accepted for participants becoming lost, stranded, injured… or worse.

Participants will be supplied a course map, which along with their own compass, will be their primary means of navigation. The course may also have a limited number of markings to re-assure participants they are on route. DO NOT RELY ON COURSE MARKINGS FOR NAVIGATION. USE THE MAP!!!

There will be several checkpoints along the route where all participants must check in. It is here that participants will receive a map for the next section of the course.

Participants may stock up on food and other supplies at stores and businesses along the route. Note… This area is extremely remote. While each checkpoint is located in close proximity to a convenience store, you likely won't find any convenience stores along the way between checkpoints. Always be aware of the distance to the next checkpoint, and be prepared to travel that distance with the supplies you carry.

If you exit the course for food, supplies, or any other reason, you must re-enter the course at the same spot at which you left.

17. Choice of bicycle type is up to each individual participant. We are allowing mountain bikes, cyclocross bikes, 29”ers, single-speeds and road bikes. Just be aware that some thought and research should go into your final bike choice. The gravel roads of Kansas can get pretty harsh. It is suggested that tire width be a minimum of 1.375” (35mm), but then again, this is up to you.

18. Participants must start and complete the entire course on the same bicycle frame. All other components and equipment may be repaired or replaced during the event. Participants in the Single-Speed class must complete the entire event using the same gearing combination.

19. Participants must wear an ANSI or Snell approved helmet while operating their bicycle.

20. Participants must obey all city, county and state laws, and "Rules of the Road". They must conduct themselves at all times in a manner that will not bring discredit to the event.

21. All participants must have a clear front headlamp and a red taillight for the duration of the event. Riders will not be allowed to start the event without proper lighting mounted and ready for use. Riders may choose to mount additional lighting while at one of the official event checkpoints. (Headlamps may be mounted either on the bike or on the rider's helmet.)

22. GPS systems may not be used by participants for the purpose of navigation. Support crews may not use GPS systems to assist any participant with navigation. However, the promoters of Dirty Kanza 200 highly recommend that each participant carry a GPS system with them during the event. Should an emergency situation arise, having the ability to communicate your exact location to support crew or rescue personnel may prove extremely beneficial.

23. Drafting on another event participant is allowed. Drafting on a non-participant cyclist, or on a motorized vehicle will result in disqualification from the event.

24. You are completely on your own. Use your head. Watch for and yield to traffic. There will be no course marshals to hold up traffic.

25. Each participant must carry with them (on their body, or on their bike) every item on this list:

Cycling computer
Red taillight
Front light (Power output is up to you.)
Minimum of two liters of water or sports drink
Two spare inner tubes
Air pump or inflation system
No rider will be allowed to start the event without each item on this list.

ADDITIONAL Supplies You Should SERIOUSLY Consider:

A cell phone to contact the “outside world” should you need help.
A GPS system to communicate your exact location to support or rescue personnel in the event of an emergency.
Small rucksack / hydration pack
Waterproof / windproof jacket
Extra thermal top or warm layer to wear if stopped
An emergency / survival blanket
Food – energy bars, gels, chocolate, etc.
Tire levers
Puncture repair kit
Chain tool
Allen wrench set
Spoke wrench
First aid kit
Butt butter

Cash, debit card or credit card. (To purchase food, water, supplies.)

Kansas Safety Tips:
When you are out riding in Kansas, the weather can change rapidly and without warning. Be prepared for wind, rain, snow, etc. with the gear that you carry. Even on a mild day, it is possible to get cold very quickly if you have to stop to fix a mechanical problem or become injured. So always carry a waterproof / windproof jacket or thermal top.

Maintain your bike so it doesn’t let you down when you are at the farthest point from civilization.

As a minimum, carry the items listed above, and more importantly, know how to use them.

If possible, ride in a group so that if someone does get hurt, there are enough people to stay with the injured person while others go for help.

Keep eating and drinking regularly to maintain energy levels. Know the symptoms of dehydration and “hitting the wall” and act accordingly.

    I think I'm going to do the 50. Ten plus hours on a bike traveling old country roads does not sound like a lot of fun...five- yes!!

I decided to start Reno Motorcycle Riders Group because I wanted to be part of a group of people who enjoyed my passion... I was excited and nervous. Our group has grown by leaps and bounds. I never thought it would be this big.
