Finally, an excuse to not wear pants. On September 10th, sport your tighty whiteys and boxers for the Undy 5000 to raise awareness—a lot of awareness—for colon cancer. Proceeds from the 5K will benefit the Colon Cancer Alliance, which “provides patient support and public education, supports research and conducts advocacy work across America” for sufferers of colorectal cancer. The Alliance has raised over $300,000 so far. Find your flashiest pair of undies and help them raise even more.

$30, ($40 on race day), September 10, 9 a.m., Martin Luther King Drive (next to the Philadelphia Museum of Art).
