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!
Gender specific, of course… and 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 Spring Fever a tradition!’

♦ 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.

Not only will both water & electrolytes be handed to you at the finish line, but course aid stations are an average of just 1.4 miles apart.

And no fees if you forget to return your timing chip either… we don’t need it back.

♦ 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!
