Course Description

A double out & back on the gorgeous Elk River Hiking Trail, just outside of Independence, KS. Accurately measured forest trail winding through unique limestone bluffs, rock formations & picturesque vistas. Mostly single-track, very rocky, no long hills.


6:30 AM start; 24-hour time limit. Cutoffs at approximate distances are; 4 hours & 30 minutes at 25K, 10 hours at 50K, 16 hours & 30 minutes at 75K and 24 hours at 101K.

The 50K and 25K cutoffs will be extended for the spring race to coincide with the final cutoff of the 101K (ending at 0630). This will allow some runners to experience the full course without extending volunteer times.

Aid Stations

19 Aid Stations; 11 fully-stocked with water, electrolyte drink & snack-type foods, including soup and sandwiches; 8 aid stations water only. Approximate distance between aid stations is 3.5 miles with no distance greater than 4 miles between aid stations.

Packet Pickup

Packet pickup starts at 5:30 on race day and lasts until the race start, obviously earlier is better. There is no Friday packet pickup or pre-race dinner. Race headquarters will be located in the Outlet Channel Group Shelter (Staging Area, north side of the Elk City Lake dam). There are several different ways to get to the Outlet Channel Shelterhouse depending upon which direction you are coming from. Please click on the link below to open a Google Map where you can get specific directions to the Outlet Channel Shelterhouse. If you have never been to FlatRock before we highly recommend allowing a little extra drive time, especially if you plan on driving in the morning of the race.

Volunteer Benefits

Along with a T-shirt and the normal fun of volunteering, we would like to do more. It takes a community to put on quality races, but volunteers also need to be appreciated. The program will be as follows: Shifts are in 4-8 hour increments and you must sign up. If you volunteer for one shift at any of our races you will get 25% off registration for any of our future races. Distance is not a factor. So 4 shifts will be a free race.

Military Discount

If you are currently active duty Military or a Veteran, we'd like to give our thanks by extending a 10% discount for your entry fee. Please message us at Outlaw 100 for the coupon code.


Prior to the race, you may defer (for any reason) to any of our subsequent races. There will be no deferments after the race has occurred. It will be your responsibility to remind us of your deferment when registering. Contact us on messenger at Outlaw 100 to arrange deferments.

Transfers to a specified individual will be allowed but it is the responsibility of the registrant to name the recipient. The Outlaw race directors will not facilitate finding another runner or run contests (this is too time consuming).

In the event of cancellation due to the Covid 19 pandemic, deferrals to other Outlaw races will be offered at no additional cost to the runner. Cancellation will only be in the event of extreme circumstances (global pandemics, inclement weather; local, state, or national emergency) and is at the race directors discretion. If for any reason the event has to be shut down due to extreme weather, natural disaster, etc… you will be pulled from the course or held at an aid station until you can be removed from the course. Please, no arguing if this should happen. It is for your own safety. If the race has to be cancelled, no refunds will be issued.

Under no circumstance will refunds be issued.
