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!

Awards and Timing

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.

Two spectators per car will be allowed free entry to Tucson Studios where the event is located. You are free to explore Old Tucson Studios after the event. If there are more than 2 spectators per car, additional entries will be sold by Old Tucson for $5.
