THE PANTLESS PARTY WITH A PURPOSE
Run a ‘Mile(ish)' in Your Undies, Because Kicking
NF's Butt is Worth the Chilly Cheeks
WHAT THE HECK IS NF?
AND WHY WE'RE RUNNING IN OUR UNDIES TO BEAT IT
NF refers to a group of genetic conditions that cause tumors to grow on nerves throughout the body. NF impacts everyone differently and may lead to blindness, deafness, bone abnormalities, disfigurement, learning challenges, disabling pain, or cancer.
That’s where we come in. Cupid’s Undie Run is a fun way to raise awareness and fund groundbreaking research for NF. By running in undies, costumes, or whatever you love, we’re showing up boldly for the NF community. We’re proving that nothing will stop us from finding a cure.
HOW IT WORKS?
