Children’s Tumor Foundation

Held in 35 cities across the United States and four cities in Australia, Cupid’s Undie Run is the world’s largest organized underwear run and benefits the Children’s Tumor Foundation (CTF). The event combines a pre-race party, a one mile-ish undie run and an after party. In 2010, founders Brendan Hanrahan, Chad Leathers and Bobby Gill set off on a mission to raise awareness and donations to the CTF after Chad’s brother’s diagnosis of neurofibromatosis (NF). A nationally recognized 501(c)(3) non-profit, Cupid’s Undie Run has donated nearly $8 million to CTF.
