Cave Creek Thriller Trail Runs

50K | 24K | 11K | 5K

Lake Pleasant to Cave Creek
On The Maricopa Trail

****RACE POSTPONED ****
October 10, 2025
For Immediate Release

Due to the recent precipitation, the watershed around Cave Creek Regional Park is saturated and the area is at high risk for flash flooding.

Between the flooding risk, the forecasted rain, and potential damage to the park trails, Maricopa County Regional Parks and Aravaipa Running have come to the decision to postpone the event.

Thrasher Night Trail has not been affected and is still a go for this evening.

We have been able to finalize our new race date, and we’re excited to share that Cave Creek Thriller has been rescheduled for December 20th.

Here’s what you need to know:

No action is needed: You’ve already been rolled over to the new date.
Can’t make it? No problem—we’re happy to offer a 100% race credit for the full amount you paid, redeemable toward any Aravaipa event.
To request a credit, just email us at [email protected] by November 1st.
After November 1st, our standard withdrawal policy will go back into effect.

We truly appreciate your understanding, patience, and support. Postponing a race is never easy, but we’re so grateful for this community and can’t wait to welcome you to the start line in December for an unforgettable race day.

Now celebrating 16 years, the Cave Creek Thriller hosts four different distances and acts as the first race of the Fall Desert Runner Trail Series.

What began as a looped course within the Cave Creek Regional Park years ago, 50K runners will have the unique opportunity to connect two regional parks in one day on the Maricopa Trail!

50 KM Event Details

50K runners will have the unique opportunity to connect two regional parks in one day! Starting at the Agua Fria Trailhead near Lake Pleasant, you’ll travel along the Maricopa Trail, a short section of the Black Canyon Trail, pass through the Anthem Trailhead along a desert corridor, climb past Spear S Ranch and finally enter Cave Creek Regional Park to finish along the Go John, Quartz & Overton Trails.

NOTE: Each year 50K runners go out too fast during the first miles (it is very runnable) and end up in trouble as they begin climbing at mile 18 and the temperature heats up (sometimes 90+ degrees). Please race smart to cross our finish line with an Ultra finish!

Aid stations every 3.0 to 9.25 miles including water, electrolyte drink, sweet snacks, salty snacks, and fruit. Please plan to run with at least one bottle of water.

50 KM: You will have a longer stretch without aid between the Start line and Deadman Aid. Terrain will be exposed, rocky, and steep. Come prepared with plenty of water to be successful in the later stages of the race!

This is a CUPLESS Race. Please come prepared with your own reusable cup or you will be able to purchase a cup on site.

Cupless Events

In an effort to continually lessen our race footprint, we are once again cupless for the Desert Runner Trail Series. We will have UltrAspire reusable cups available at registration and on race day or feel free to bring your own! To check them out or purchase one directly visit our website HERE.

Trail Etiquette
Remember to always remain on designed trails, no short cutting.
If you decide to use headphones, please be respectful of runners behind you attempting to pass. Also, remove ear buds as you approach aid stations or a road crossing.
Please do not listen to music with a speaker (yes, we know you listen to the best music).
This course includes some legit single track. If you are fast and attempting to pass, please alert the runner in front of you before flying past them. Likewise, if you hear a runner approaching you from behind, attempt to find a spot to allow the runner to pass.

As a general rule, when passing a runner, announce, “on your left.”
Uphill runners/hikers have the right of way to downhill runners. Remain in control as you descend and respect the other

Volunteer Helpers
If you would like to join our volunteer team, we are looking for help with event setup, aid station captains, aid station helpers, timing, photography, videography, social media, course sweep and event breakdown. Volunteer perks include a piece of Aravaipa merchandise or race goody and Aravaipa Race Credits. You can see our current opportunities and sign up here: Cave Creek Thriller Volunteer Form

For the 2024-2025 Desert Runner Trail Series, Aravaipa Running will be working with the Southwest Wildlife Conservation to assist in their mission rescues and rehabilitates wildlife that has been injured, displaced, and orphaned.
