Too many race shirts to wear ’em all?  Not a fan of goodies in a bag?  That’s cool… just enter this discount code when you register and bam… $5 saved!  (Don’t worry, you’ll still be sportin’ that finish line bling with a burrito filled belly when you download all those free race pics!)

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, late and walk-up entrants 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.


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

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?
