February 11 - 13, 2023
This Event Took Place Mon. Feb 13, 2023


Run in the footsteps of actual OUTLAWS!! The Outlaw course is located in the Robbers Cave State Park near Wilburton, Oklahoma. Robbers Cave State Park (established in 1935 by the Civilian Conservation Corps) is associated with OUTLAW names like Jesse James, Belle Star, and the Youngers. The Park consists of 8,246 acres of scenic views with bluffs overlooking three large lakes, rock formations, and caves to be “enjoyed” as you navigate the mainly single track, forested, technical terrain with an abundance of rocks and roots.

Outlaw Trail Series

Complete all 6 trail runs in the Outlaw Trail Series (Outlaw, Lake McMurtry, Greater Roadrunner Trail Run, Flower Moon, Dark and Dirty, and Thunderbird) in the calendar year 2023 and receive a cool plaque to recognize your achievement. Distance is not a factor (in other words, you can run the 5K or the 135mile). Virtual options do exist that allow runners to complete the series even if they are unable to attend an event in person. An Oklahoma-shaped plaque with hooks looks great as a display for awesome medals.

Outlaw 135

There has been increased interest in the longer distances, especially the 200 mile races. This is a nice intermediate to test yourself and develop strategies for those longer runs. The Outlaw 135 mile course is made up of the 100 mile course with the bonus of the 7 mile loop an additional 5 times. This allows runners to be monitored more closely by the start/finish aid station late in the race and concentrate volunteers. Same Saturday morning start time the 100 mile run with a 48 hour cutoff (see cutoffs in section below). We do allow drop downs to still get a 100 mile buckle or longest distance completed as in all our runs (but not qualify for place). The 135 mile has about 21,000 feet of gain.

Outlaw 100

The Outlaw 100 course consists of a large 13 mile southern loop and a smaller 7 mile northern loop. Together, these loops comprise a unique 20 mile segment that must be completed 5 times. It includes two awesome aid stations manned by experienced Ultra-runners alternating with water stops. The 100 mile course has about 15,000 feet of gain and is over 95% single track. In terms of difficulty, which is subjective, this race might be characterized as intermediate/difficult. The course has very technical terrain with a lot of rocks and moderate gain (but is at an altitude of about 1,000 feet). It is not a rails-to-trails or gravel road thus the lengthy (albeit) generous cutoffs. As in all long courses, water crossings (defined as you MUST get your feet wet) are possible depending on rainfall prior to the race (especially at 1.25 miles and 9 miles). In the event of significant rainfall, course variations are preplanned and possible. Please see the course maps in the pictures above or at our website (gpx files also available) at www.Outlaw100.com.

50 Mile, Marathon, and Half Marathon

The half marathon is a 13.1 mile loop. The marathon consists of two loops and the 50 mile consists of four loops (thus the 50 mile is about 52ish miles). Cutoffs for the 50 mile, marathon, and half marathon (all races aside from 135 and 100 miles) are 10Pm Sunday night. This gives 39.5 hours for the 50 mile and 14 hours for the Sunday half and full marathons.
Please see the course maps in the pictures above or at our website (gpx files also available) at www.Outlaw100.com.


The most scenic 5K in Oklahoma!! The 5K course will encircle the main cave and provide plenty of adventure in a shorter distance. Please see the course maps in the pictures above or at our website (gpx files also available) at www.Outlaw100.com.

Run it Saturday or Sunday or do the virtual.

Doublers will receive an Outlaw special item. You must complete a distance of a half marathon or more on one day and at least the 5k on the other. One run must be in-person.

Virtual 5K

Unable to attend and still want to participate? Virtual options do exist that allow runners to obtain a coveted medal or complete the series even if they are unable to attend an event in person. We realize that other life obligations come up.

Child Discount (in person only)
Outlaw events are meant to be amongst family and friends. As such, any parent entry will entitle one child (15 yo and under) to a free entry of same or lesser distance.

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 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.

Deferal / Transfer Credit (to a different race)

If you can no longer run the event you registered for, we offer the below-sliding scale prior to the originally schedule race date for receiving credit to a different Outlaw event. We do not offer refunds, deferrals, or transfers - only future race credit. The credit will only be useable by the original registered participant and only for Outlaw events. Unless otherwise stated, credits will be valid for two years from the original event date. Credit will be the amount paid minus taxes and fees. Transfers are a one-time opportunity. You cannot re-transfer a previously transferred race. Once credits have been issued, they are gone. This includes any credits used from volunteering, race credits, previous credits, or credits transferred. The submission date will be used to calculate the credit amount.

30-89 days out: 75% credit

Runners starting a race but not finishing the intended distance will be listed as a DNF at the bottom of the results for their registered distance. Runners may not be “dropped down” to a shorter distance once they start a race, and will not appear as finishers of the shorter distance. This ensures a fair event where runners know their competition and cannot be lowered in place by a runner dropping down in distance. Runners may switch distances before the start of their race and will be eligible as a finisher in that event

DNF: Runners starting a race but not finishing the intended distance, in the intended order as marked, and under the official cutoffs,will be listed as a DNF at the bottom of the results for their registered distance.

We believe in fostering a respectful and supportive race environment, and these rules are in place to uphold that.

Dropdowns: Runners may not be “dropped down” to a shorter distance once they have started a race and will not appear as finishers of the shorter distance. Runners may switch distances before the start of their race and will be eligible as a finisher in the updated race distance.
