5KRunDead (Sept/Oct), Brownsburg

Running is a great way to stay healthy in general; it's also the only way to stay healthy if you're on the course of a 5KRunDead race. Each competitor is armed with flags, and as zombies nab them, they grow weaker. The fastest and nimblest get rewarded with prizes at the end. Zombies are rewarded with prizes, too, plus the fun of being transformed into genuinely gruesome creatures by pro makeup artists. Proceeds seek to spread good health far and wide—100% will benefit cancer and Alzheimer's research.
