Our Cause

In addition to our desire to bring a world-class event to Owasso, Julia and I strive to increase awareness about prescription drug abuse.  This issue has had a major impact on our family, and we hope that others will join us in the cause and help fight this epidemic.  Click here for more information on the topic.  We also encourage you to explore other sites and learn as much as possible to help your family and the thousands of others affected by the prescription drug and opioid crisis in America.

Event Details
​The event is a 24-hour track race with a variety of race options.  Additional options include *Dave's Challenge, 100-mile, 100K, 50-mile, 12-hour, 50K, 6-hour, 26.2-mile, 13.1-mile, and **5K events.  Time limits for the distance races are 24-hours for the 100-mile, 100K, and 50-mile  and 12-hours for the 50K, 26.2-mile, and 13.1-mile races. There will be a 1-hour time limit for the 5K.  Any 24-hour participant who reaches 100-miles will receive an official 100-mile time in addition to a 24-hour distance.  Participation will be limited to 100 competitors, and registrations will be filled in the order they are received.

*Dave's Challenge: complete 1 mile during each of the 24-hours of the event

**5K: Begins at 9:00am and ends at 10:00am on Sunday, March 17th


The race is a qualifying event for the 2019 IAU 24-Hour World Championship.  The race is intentionally held on a certified track to provide participants with a flat, cushioned surface to achieve their best performance.  All efforts will be made to respect the endeavors of competitive athletes while promoting safe and fun  environment for all participants.

Dave's Challenge
We encourage 24-hour participants to test themselves by committing to Dave's Challenge to honor Lhotse athlete Dave Renfro.  Dave participated in every Lhotse event while battling stage IV renal cancer.  Dave's strategy was to keep moving, despite the pain and personal struggles to reach his goal.  The rules to Dave's Challenge are simple...complete 1 mile during each hour of the race, for a minimum total of 24 miles with at least one mile being done each hour .  All participants in the challenge will receive a custom Dave's Challenge t-shirt to remember Dave.  Dave loved his Lhotse race shirts, and we want to honor him by making one for him this year.  This is a special addition to the 2019 race to honor the memory of our friend Dave Renfro.

Laps will be recorded by electronic chip timing and will be submitted for USATF record purposes.

You may leave the track at any point in time during the race, but you must return to the same place before continuing. You may not leave and return directly by the timing equipment, to avoid double counting a lap. Your number of laps, distance, and race will be shown on an electronic display near the start.

Awards will be given in Male and Female categories for the 24-Hour, 100-mile, 100K, 50-mile, 12-hour, 50K, 6-hour, 26.2-mile, 13.1-mile, and 5K overall individual winners.  Belt buckles will be provided to 24-Hour and 50-mile finishers. 

​All runners will receive an event specific race shirt, and all finishers will receive a finisher medal.
