Alright… it’s almost time.

Monkey Butt Mayhem is tomorrow.

Get your gear ready.
Double check your alarms.
Try to get some sleep (we know, easier said than done).

Tomorrow: trails, community, cookies, and a little bit of chaos.

We can’t wait.

Good night—and good luck.

🐒 Banana-levels fun awaits while getting essentially the best stair-climbing workout you could ask for! A hill repeat challenge where hiking is encouraged because the goal is finishing short race loops, collecting as many feet of elevation gain as you can get in the time limit. Choose from 3 or 6 hours to take on Monkey Butt Hill on the Cross Timbers Hiking Trail. Run or jog the downhills and hike the climb, while taking breaks whenever you need.

Imagine a race where there's a monkey's butt on your entrant item, your finisher medal, and on any awards you win. A silly vibe and a fun race format await you, named after Monkey Butt Hill on the Cross Timbers Trail north of Dallas, TX. Runner and hiker friendly, with a cookie-only aid station too!...

🐒 Your next trail adventure with The Active Joe is right around the corner, and it's wildly entertaining! Named after the infamous Monkey Butt Hill on the Cross Timbers Trail, that short but steep climb gives you 100 feet of elevation in just 1/10 of a mile. Athletes tackle it again and again to see how many loops they can complete.

Your options:
⛰ 3-Hour Challenge – climb as many loops as you can
⛰ 6-Hour Challenge – double the time, double the fun
Expect a race that doesn’t take itself too seriously — including a cookie-only aid station and plenty of encouragement from the trail community.

Bananas! 🍌 Our runners went all in on the Mayhem.
Together, they spent a wild 105 hours on the trails — that’s over 4 days of climbing that hill!
Huge thanks to everyone who came to swing through the course with us! 🙌
And thanks to participant Kelsey Long for these action shots!

Big Thank You to Kelsey Long who ran the 3 hour but ALSO took a lot of pictures along the way to share with the runners! You can see your pictures here: https://www.facebook.com/media/set/?vanity=kelseylong&set=a.10110778326394305 - also shoutout to Kelsey who took a trash bag with her out on the second loop when she saw that someone (not associated with the race, happened before race weekend) had dumped about 10 lbs of trash out on the side of the trail! She collected it all and brought it back to the finish, and thanks to Andy Rose for taking it to the dumpster! Being eco-conscious is super cool - let's take care of our lands!
