We attract heroes, party animals, undie-lovers and the generous-as-hell. We're fighting NF, a rare and deadly disease that affects 1 in every 3,000 births. We will win. Are you in?

What’s up with the undies?!

Raising money to cure a nasty genetic disorder not enough for you? OK, how about a one mile-ish run in your underwear in the middle of February, topped off with a wicked pre-game and after-party, great company, and more fun that you’ve EVER had on a Valentine’s Day?

We know… we had you at “underwear.”

Cupid’s Undie Run started with the goal of raising money to #EndNF and, having raised $3.5 million last year, this thing just keeps getting bigger.

Pants drop this February. Be there!

Join in and take part in the best, craziest thing you’ve ever done. You’ll tell your grandkids about it – and sleep well knowing you helped raise millions for the Children’s Tumor Foundation.

Why we run

Tomorrow a new family will have their world turned upside down, they will be told that their child has a rare nerve disorder they can barely pronounce. There will be MRIs, many more doctors visits, and currently no treatments. We run and raise because we believe there is a solution to end NF and through the research guided by the Children’s Tumor Foundation and the funds we raise, we will find it.

Cupid’s Undie Run isn’t your typical “fun run.”

Fundraising is our #1 priority, and the numbers speak for themselves. Just look how things have changed over the years.

Started from humble beginnings between a few friends looking to make a difference, Cupid’s has grown from a single city raising $10k to $2.8 million fundraised in 2014. In 2015, we raised $3.5 million, bumping our cumulative total over the years up to almost $8 million. And we’re not stopping there.

Those fundraising dollars don’t just magically appear, though. That’s where you come in.

Register to run or donateHeck, do both.
Either way, partner with the pants-less and help us #EndNF!
