WAIT… don’t register until you’ve checked out the deep
discounts & primo perks that come with our Run Amok Series!


♦ RRCA Certified Race Director- Organization you can count on!
With more than 75 events under the belt of our director and a staff with 25+ years experience, your event will run smoothly. (Ha! No pun intended.)
♦ Early AND Race Day Packet Pick-Up- For those who like to prep in advance!
Sure, picking up early gets you another chance to win a prize, but no worries if you wait until race day… we make it quick & easy.
♦ Race Shirts- The one you’ll want to wear EVERY day!
Long sleeved, & gender specific, of course… still poly for those moisture wicking properties, but with a touch of cotton for extreme comfiness.
♦ Finisher Medals- Custom molded & distance specific, even for the 5K!
Then a little something special for our 1 Milers too.
♦ Brag Tags- For all repeat finishers!
Our little way of saying ‘Thanks for making Polar Prowl a tradition!’
♦ Souvenir Race Bibs- Event specific and personalized!
Personalized for all who get in by the advanced deadline… yet another keepsake to remember your day!
♦ FREE Race Pics- Unlimited downloads are on us!
Professional photographers at the finish line AND on course… enjoy!
♦ Gear Check- No trips back to the car for our athletes… no sir-ee!
Leave it with us… we’ll keep an eye on it for you.
♦ Porta-Poos-A-Plenty- 3 Units for 500 people? What, are you crazy?
Ever had to run without using a restroom because the lines were too long? Us too… ouch! We provide more than TRIPLE the facilities as other events.
♦ Accurately Measured Courses- Race the distance you trained for!
Not a little more and not a little less… we measure each course no fewer than 3 times before race day and mark them so they’re crystal clear.
♦ Medical Support- Nothing is more important than your safety!
Here’s hopin’ those guys are really bored, but just in case… you’ll find our med crew both at the start / finish AND on course.  Plus, each and every volunteer you pass knows who to call for help.
♦ Tons of Aid Stations- No need to carry any extra weight!
Not only will both water & electrolytes be handed to you at the finish line, but course aid stations are an average of just 1.2 miles apart.
♦ Disposable Timing Chips- No hassle at the finish line!
And no fees if you forget to return your timing chip either… we don’t need it back.
♦ Electronic Results- No more endless sheets of data to sort through!
All results scroll on easy to read computer screens in the expo area during the event and are posted online by the end of the day.
♦ Text Results & Placements- Individually sent to all who opt in!
Just provide your mobile number with your entry, then text the keyword ALLOUT to 550055 from that mobile device.  Yup… it’s that easy!
♦ Post-Race Meal- Breakfast tacos, fruit, bagels & chocolate milk for all!
Yup, even if you’re dead last… we’re not going anywhere until we cheer you in.
♦ 3 Deep Awards- Overall AND Divisions!
Events small enough to stay friendly and personal give you a better chance of landing on the podium! (1 Mile awards will be given to the top 3 in each gender only, for the time being.)
♦ Prizes Galore- If you’re registered, you’re entered… easy peasy! Just bring us your ticket at the start of your award ceremony and you’re in! (Psst… in most cases, everyone who sticks around for the giveaway goes home with a prize!)

Discount Code:  NOSWAG

IMPORTANT: Your decision to forego your race SWAG and register at the reduced rate is final. The moment you provide payment information & click to process your entry, changing your mind to add a shirt and goodie bag later will not be an option under any circumstances.

*Because goodies must be ordered far enough in advance to have them printed & shipped, athletes who register during late pricing will receive SWAG on a first come, first-served basis.  If the shirt size you prefer is unavailable when you register, please select your next best size to be sure you get one, then stop by the packet pick-up area after you race to see if a swap is possible.

**To be certain those who registered earliest receive the shirt size they requested, athletes who enter during walk-up (at Early Packet Pick-up or on Race Day) will need to wait until after they race to select from the sizes available.


Without YOU, these events simply wouldn’t be possible!

There’s no experience necessary, but space is limited so please let us know you’re available right away! Athletes: We know endurance sports can take a big chunk out of your pocketbook and we’ve got your back.  Check out our ‘Earn a Free Entry’ program! Groups: Tired of those bake sales & car washes? We are happy to be a part of your fundraising efforts! (Donations begin with just 10 volunteers and you need not be an official nonprofit.) Students: Earn those credits in the most fun way possible!
