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?

Cupid’s Undie Run – Baltimore

This Valentine’s Day weekend, come put the hilarity in charity with hundreds of half-naked runners taking to the streets in celebration of their fundraising for the Children’s Tumor Foundation.

Be a part of something great. Last year Cupid’s raised over $3.5 Million to #EndNF and we’re relying on YOU to join and make this year’s fundraising (and party) the biggest and best yet.

Start a team, join a team, or just run solo and make some new friends!

  • Noon – Doors open & the party starts!
  • 2:00 PM – UNDIE RUN
  • 3:15 PM – Awards ceremony
  • 4:00 PM – Bag check closes, Cupid’s officially ends

We recommend public transportation (the Orange Circulator stops closest) or car service (Taxi, Uber, Lyft). However, if you want to drive, we recommend parking at the Pier V Garage on Pratt Street and assigning a designated driver.

Our Goal

Start a team

or Go Solo

Running in your undies is more fun with friends!

Recruit some friends, join a pre-existing team or just go solo. So many choices, so little clothing!

NEW: Compete in fundraising leagues with like-minded cherubs. Nothing like some friendly competition amongst peers to keep things fun!

Just want

to help?

We get it, undies aren’t for everyone… but raising funds for the Children’s Tumor Foundation definitely is.
Too young, too far away, not … in to undie running? Join the campaign and donate your birthday!


Spread the love

YOU can make an impact and we hope you take on the challenge.

Whether it be $50 or $5000, we will make the most of your efforts. Proceeds benefit the Children’s Tumor Foundation, and this year, we’re shooting to top last year’s total of $3.5 million.


Cool Stuff

Cupid’s undies are never sold, only earned!

Earn your undies, open bar status, custom’s Cupid’s swag and more when you fundraise your pants off!

our heroes

Tomorrow a new family will have their world turned upside down – they will be told that their child has a rare genetic 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!
