JOIN US THIS FEBRUARY TO FIND A CURE FOR NF

Cupid’s Undie Run kicks off with drinking and dancing, then we jog it out with a mile(ish) run and end it all with an epic dance party! So register now – start a team or run solo – and start fundraising to earn Open Bar, undies and more!

UPCOMING EVENTS

WHY WE RUN IN OUR UNDIES

and how it's making a difference.


We run in our undies because those affected by NF can’t cover up their tumors. They can’t put on clothes to feel more comfortable, so why should we? Since 2010, we have brought together over 89,000 undie runners to build a community of supporters that just won’t quit. Our community has raised over $16.9 million since the inception of Cupid’s Undie Run, with 100% of net proceeds funding NF research, through our partner the Children’s Tumor Foundation. And we are seeing real results, including a ground-breaking clinical trial where 70% of participants experienced 20-50% tumor reduction! But we aren’t even close to being done, and we won’t stop until we #EndNF.

FREQUENTLY ASKED QUESTIONS

Is this a run, or a party, or both?!

BOTH! Cupid’s Undie Run kicks off with mingling, music, and drinks. Then we all head out for a mile(ish) run and stretch it out back inside at an epic dance party.  It’s all for charity, and it’s all in your undies!

How do I earn cool stuff?

The more you fundraise, the more rewards you’ll earn. Want the Cupid’s commemorative t-shirt?  Raise $100! Want to add undies, and the coveted open bar to that? Raise just $250!  Check out all the other rewards you can earn here.

What do I get for referring friends?

Have a friend register using your personal referral link and you’ll receive $15 towards earning some awesome Cupid’s swag. At the same time, your friend will receive 15% off their registration fee. And there is no limit to how many people you can refer. It’s a WIN, WIN, WIN!

What should I wear?

Well, we will definitely be in undies! However, if undies aren’t your thing, get creative with it and try out a costume, tutu, or onesie! Have fun with it, but remember, it’s for the kids, so we ask that participants keep it PG-13.

Where does the money go?

Cupid’s Undie Run is a fundraising event with 100% of the net proceeds funding NF research through the Children’s Tumor Foundation, a 4-star rated charity, and the world’s leader in NF research.
