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.
