If you happen to see people running around half naked in Venice on Saturday, they haven't lost their minds, only their clothes. Cupid's Undie Run, a pantless party and run for charity, happens every February extending sexy Valentine's Day vibes with heart-themed dress-up and revelry. Looking to raise awareness for neurofibromatosis (NF), a genetic disorder that laves sufferers with nerve tumors inside their bodies, the undie-clad crowd also hopes to also raise funds for NF research via the Children's Tumor Foundation (CTF). Runners from across the U.S. come together (in-person and online) to highlight the genetic disorder, which affects 1 in every 3,000 births, and L.A.'s is always a scene due to the great weather. The event also features drinking and dancing after the jog. Meet at the Venice Whaler, 10 Washington Blvd. Sat., Feb. 19. 12- 4 p.m. More info at my.cupids.org/cur/city/losangeles
