Flowers, chocolates, and cards might be enough for most folks on Valentine’s Day. But for a special breed of Seattleite, the Hallmark holiday is not complete until they have paraded through the streets of Fremont in their drawers and g-strings.

That’s exactly what hundreds gathered this past Saturday to do during the annual Cupid’s Undie Run, a charity fun-run benefiting The Children’s Tumor Foundation. The organization is researching a cure to Neurofibromatosis, a genetic disorder in which tumors grow on the nervous system, causing chronic pain, blindness, and learning disabilities.

Those who stripped down on Saturday raised tens of thousands for the organization, nevermind getting a rare opportunity to run through Fremont in your bedroom’s finest as well as enjoy some post-run drinks and dancing at the Fremont Ballroom bar.

The charity run took place in 30 cities in 2014, raising $2.8 million. It expanded to 38 for 2015, with a goal of raising $5 million.

See the full slideshow of Saturday’s run here.
