Race Rules For Runners
1. Numbers must be worn on the front and outside of what you are wearing. It is the runner’s responsibility to make sure their number has been checked in at each aid station. Do not run by any aid station without checking in. Especially Note: RIDGELINE AID STATION, you MUST run off the road approximately 40 - 50 yards to the aid station and check-in. Even if you don't need anything, DO NOT yell from the road and keep on going. Entries are non-transferable.
2. Absolutely no littering! This entire course is run on county roads and through private property and we do not want to jeopardize our ability to utilize this land.
3. RUNNERS are RESPONSIBLE for the actions of their CREWS.
4. You may not stash supplies along the course.
5. You may have as many pacers as you wish, but only one pacer at a time.
6. Any runner dropping out shall immediately notify the nearest aid station or race management at the
7. Runners should avoid dropping at Texaco Hill aid station. Texaco Hill aid station is remote and difficult to get to. Runners dropping here will have an extensive wait before a ride back can be available. If at all possible, runners are encouraged to continue to the next manned aid station.
8. Runners accepting a ride for any reason are deemed out of the race and may not re-enter.
9. Cutoff times are nonnegotiable. Runners must DEPART the aid station by the listed cutoff time
10. All runners will abide by the directions of race management.
11. Please run facing oncoming traffic.
12. Do not chase the cattle. At various sections of the course you may encounter livestock on the road.
They will be curious, may gather around you, or even run toward you from a distance. REMAIN CALM,
they are gentle animals. The safest way to proceed is to walk through the herd when you encounter them
as they will move out of your way. Running and shouting will cause the animals to scatter quickly and
there is always the possibility you will be in each other’s path.
13. Violations of any rule will be grounds for disqualification. Race Management reserves the right to bar
any runner from competing in this and any future KUS races.
14. In the case of a tie, runners will be placed alphabetically.
15. Decisions of Race Management are final.
Rules for Support Crews

3. No Littering.
4. All animals must be leashed at all times.

“No Smoking” on the course.

Flat Tire Warning – Some of the sharp rocks on the roads on which you will be traveling can cause flat
tires. Historically the volunteers have averaged a couple of flat tires a year. It is best if your crew vehicle
has a good set of tires, a good spare and you know how to change them. The best way to avoid a flat is
to drive slowly. You will have plenty of time to get between aid stations to meet your runner and driving
slowly will improve your odds of avoiding a flat.

Kansas Weather Risks
We have chosen to hold the race in October to minimize the impact of the Kansas weather. In August the
temperatures could be over 100 degrees, with 30 mile per hour winds, which would make this a very tough
100-mile race. We could also have held the race in the springtime when the prairie is the greenest. However,
the likely hood of thunderstorms is greater which would have made this a more dangerous race. While
October is normally a very mild month, this is Kansas so come prepared for all possible conditions. The
following are the historical weather statistics.
Normal High – 70
Normal Low – 44
Record high of 89
Record low of 30
Sunrise – 7:35 AM
Sunset – 6:54 PM
Severe storms do not normally occur in the fall; however they are possible at any time in Kansas. Tornadoes
and blizzards have both occurred in the month of October. There are very few locations on the Heartland 100
course where there is shelter from the elements. Whatever the conditions, you will feel them. Be prepared
for them. While tornadoes get a lot of publicity, lightning is the greatest danger. Lightning often strikes the
highest object and on the course, you will often be the highest object. In the unlikely event of a severe
thunderstorm the best course of action is to take whatever shelter is available at the lowest location.
Each runner is responsible or their own actions. It is crucial that you are physically and mentally prepared
for the stresses of the race. We will utilize the local EMS services in case of a medical emergency.
While the course is on roads, the remoteness of the area and the distance between towns will result in a
substantial amount of time before they arrive to provide assistance.
It is important for the runner to recognize the potential physical and mental stresses that may evolve from
participation in this race. These include, but are not limited to, extreme temperatures of heat and cold,
hypothermia, dehydration, heat stroke, renal failures, seizures, hypoglycemia, disorientation and total mental
and physical exhaustion. Each participant must continuously monitor his/herself and understand their limitations.
Remember that you are responsible for your own well being during this race.
All manned aid stations will also serve as supply drop bag locations for runners. NOTE TO 125 MILE RUNNERS - Drop bags at TEXACO HILL MAY NOT ARRIVE UNTIL 9:00 AM, Please plan accordingly. Drop bags must be no less in strength than double thick plastic bags and securely tied. Please keep all drop bags at a reasonable size, (approx. shoe box size). Each bag must contain the runner’s name, race number and aid station. Placing wide white tape on the bag and then writing on the tape with a black felt tip marker is preferable. If you place any liquids in your bags, make sure they are in leak proof containers. Drop bags can be left at the Cassoday community center on Friday and can also be brought to the Cassoday community center on Saturday morning, as long as they arrive before 5:30 AM. All drop bags will be available for runners to pick up at the Cassoday community center by 1:00 PM on Sunday. It is each runner’s responsibility to pick up their drop bags on Sunday. Any drop bags remaining will be donated or disposed of.
Limited camping space is available at the Cassoday City Park. Facilities are limited to drinking water and
outdoor toilets. They are free of charge for the runners. Additional camping facilities are available at
El Dorado State Park, which is approximately 20 miles south of Cassoday for a small fee. A KOA campground
is also located in Emporia. The following are a list of some lodging options:
Cassoday Motel and RV Hookup
302 E Main
Very limited number of rooms
El Dorado State Park
618 NE Bluestem Rd.

Motels – Emporia (34 miles north on I-35)
Motels – El Dorado (22 miles south on I-35)
Motels – Wichita (40 miles south on I-35)
Possibility of Race Cancellation - In the unlikely event the race is canceled, these are the protocols we will follow.
1) Our first responsibility is for the safety of all involved. Runners and their crews, race staff, volunteers, aid station workers and radio communication personel and spectators.
2) Though cancellation of the race is highly unlikely, there is the possibility. This would only occur if severe thunder storms are present with lightning also present at the start location and national weather service and local observation shows this is continuing for the duration of the event along the race course and vicinity.
3) A more likely situation would be to delay the start until the severe weather has passed. Then everyone as responsible adults, proceed at your own risk. As runners ourselves we know the work you put into getting ready for this day. If it were just us runners we would run regardless. But in a race setting there are others to consider besides ourselves. We hope you can appreciate this policy and not try and "wing it" if we do indeed make the decision to cancel the race.
4) To summarize, possibility of cancellation is near zero, and the decision to do so would only be possible at the start at the scheduled start time. For you folks traveling a fair distance to get to the race, I'm sorry we can't be more precise.
5) Due to Covid-19: The possibility we may be forced to cancel is NOT ZERO! Please be aware, we will do everything possible to have an enjoyable event for all.
No Refund, no transfer of your entry to another runner. We will carryover your registration for one year if notified before registration closes and bib numbers are assigned. No refund or carryover after bib numbers are assigned, or if no show, or notified after Friday packet pickup. When notifying us that you need to defer your entry, we will confirm your request. Please make sure you get confirmation from us. If you don't receive timely confirmation, send us another message. Any late, misdirected, lost communication will result in your request for deferred entry to be denied.
Frequently Asked Questions
Are trekking poles allowed?
Local time: 11:11 PM
Yes, trekking poles are allowable equipment for our races.
Is there a course map?
Yes, there is a course map with elevation profile in the pictures section. There is also a map for crew directions to the crew accessible aid stations. Just click on the thumbnail picture to bring up a full size view.
Is there an athlete tracker?
We do not have "Live Tracking" of the runners. We track runners thru each manned aid station, and communicate via Hamm radio. So while we do know the approximate location of each runner, we do not have live reporting for spectators to follow.
Are dogs allowed on the course?
Sorry but dogs are not allowed on the Heartland course. Much of the land is open range with Cattle grazing loose, with the uncertainty of reactions between cattle and dogs we have to be cautious and prohibit dogs on the course. Your crew can have your dog, (leashed), but not out on the course.
Why 14 hr cutoff at 50 mile turn around. Why not 15 hr?
If you cannot reach 50 miles in 14 hours, it is unlikely you can make the return trip (2nd 50 miles) in 16 hours.
Can you drop down from 100 mile to 100K or 50 mile during the race?
Due to the out and back nature of this race, there is not a drop down option. If you start the 100 mile race and do not finish 100 miles before the cutoff time, (noon Sunday,) you are listed as DNF. You do not receive credit for a 100K or 50 mile finish, even if you run 100K or 50 miles or more.
Is it all gravel and road or is some of it trail?
The Heartland 100 course is 99% back country gravel/dirt roads. With 1% Paved Road in the town of Cassoday.
