Cupid's Undie Run is a 1+ mile run around the US Capitol in your bedroom-best, all for a good cause: The Children's Tumor Foundation!

The Children's Tumor Foundation is the world's largest non-government organization dedicated to ending Neurofibromatosis (NF) through research. NF is a genetic disorder that causes tumors to grow on nerves throughout the body, causing blindness, deafness, learning disabilities and severe chronic pain. Currently, there is no cure for NF and there are frighteningly few treatment options. The Children's Tumor Foundation is a Charity Navigator 4-Star charity that prides itself on efficiency, spending 82.4% of its revenue on program expenses and less than 8% on administrative costs.

NF affects roughly 1:3,000 births in the U.S. and is in desperate need of new discovery, which is why 100% of funds raised through Cupid's Undie Run go directly to the Children's Tumor Foundation.

The Foundation's mission is to advance peer-reviewed research to develop treatments and cures for NF; support persons with NF and their families by making thorough and accurate information readily available; to assist in developing clinical centers and best practices to improve access to quality healthcare for those who live with NF; and expand public awareness of NF to improve diagnoses, increase understanding of the challenges that NF presents, and encourage support for NF research.
