Race day details:Location
The Flagstaff Extreme Terrain Mud Run is 3 miles south of Flagstaff, Arizona, in the historic Fort Tuthill County Park. Take exit 337 of of I-17 and go west. Our course will start and finish underneath the treetop adventure course FLG Extreme with zip lines, balance beams, and cargo nets above the course.
There will be three different packet pickups available:
You can race on a team or solo, but mud runs with friends are so much more fun!
After buying an entry, you can decide if you want to race on a team. You will have the option to create a new team or join one. So you don't have to sign your whole team up at the same time.
Why race on a team? Teams of 5 or larger (no limit!) are eligible for our best dressed team award, largest team award, and each teammate will get a coupon to save on future races and merchandise!
This is a race and all athletes will be timed! Your time will be slower than a 5k or 10k race, but it's always nice to see how you rank compared to fellow athletes.
We use chip timing so you can see how fast you really are and we provide you with a free printable finisher certificate online after the race.
The 9am wave of the 3 mile and 5+ mile courses is a competitive wave. The fastest three men and women in each distance will receive a free entry to another terrain Mud Run.
The Endurance distance is two laps on the 5+ mile course and all athletes must start at 9am. The fastest three men and women in the Endurance wave will be eligible for prizes.
We create a finish area that includes many exciting obstacles for spectators to watch their family and friends on.
There is no charge for spectators at our Flagstaff event and we encourage you to get a cold beverage, grab a bite to eat and hang out under the ziplines to cheer on your friends and family!
Each athlete will get a free beverage: a Mother Road beer, or bottled water.
Lunch and extra beverages will be available for purchase.
No outside coolers are allowed at the venue. You may bring water, energy drinks and snacks to the site but please leave other items at your vehicle.

Camping is available just 100 yards from the start line for as little as $16 per site per night. Get details on the Fort Tuthill website.

For ages 9-15. Ages 9-13 must race with a parent. This course follows the regular 5k course, it's just cheaper for those under 16.
Best for first timers and athletes that want to have a great time. If you can jog 3 miles and do a couple pushups and sit ups, you can do our 5k course! You'll be ready to slosh in the mud, jump over 6 foot high walls, 12 foot high rope walls, and 16 foot high cargo nets.
If the short course sounds too easy, get ready for a tougher course with 5-7 miles of running and over 20 obstacles to really challenge you. This is for athletes that want a tougher course and more obstacles.
Two laps on our 10k. For athletes that like to run and do over 20 obstacles, twice. Cash prizes and gear prizes for top winners. You must do the 9am wave if you choose this race.
