Three men—Mike Sacco, Lejon Boudreaux and ultra-marathoner Dean Karnazes—have joined with the Black AIDS Institute to raise awareness for World AIDS Day, December 1, by participating in the Run-in-a-Million Run from San Francisco to Los Angeles (earthtimes.org, 11/30).

The 510-mile marathon will begin tomorrow on World AIDS Day and end on December 14. At the end of each day of running, the men will participate in local activities to raise awareness and encourage people to learn their status.

”Our goal is to raise money to end the AIDS epidemic and to reach at least 1 million people with messages about HIV testing, treatment and stigma. We will speak to people about the importance of each person taking part in this critical fight in their own individual way,” says Sacco.

A blog about the run will be posted on blackaids.org.
