The 2017 TRC POSTOAK Challenge will be held February 24, 2017, February 25, 2017 and February 26, 2017

Online Registration is open!

From the Race Director: All new for 2017, The POSTOAK Challenge Triple!!!!


We will run a 26.2-50k-26.2 Triple, a grand total of 83.5 miles in three days of trail running. You can also run a 13.1-25k-13.1 Triple for a total of 41.75 miles. These are the only Triples we are offering. The Friday marathon and half marathon will start and finish at the Pole Barn which will also be the bag drop, there will be three Aid Stations. The marathon will be four loops, the half marathon will be two loops, they will stay in the upper trails, no going over Holmes Peak, no Hill From Hell. It will, by far, be the easiest of the three days.

At the TRC POSTOAK Challenge our philosophy is simple, let's run and have fun, it is a weekend party for all involved. We have the best Aid Station Sponsors you will find anywhere and they make sure you are taken care of and that you are having fun. Our motto is "You are not only paying a registration fee, you are paying a cover charge".

If you are not quite ready for the Triple, you can always run a Double. All you have to do is run one race on Saturday and another race on Sunday. That gives a runner nine ways to double. The most popular this year was the 50K / 26.2. That's 57.3 miles of rugged trail running in two days. The best part about the event is that everyone has so much fun. Even runners who could not compete on the second day were smiling and having a good time cheering on their friends.

The TRC POSTOAK Challenge is directed by a Volunteer Committee comprised of local runners to benefit the Tulsa RiverParks Authority. For more information or to contact the Race director please email us at
