This just illustrates what I've been saying all along: exercise is very, very bad for you.

LATimes:

The weather was perfect, the field enthusiastic, the times respectable, but Los Angeles' annual street party masquerading as street race was marred Sunday by the deaths of two runners and the collapse of an elderly man who was hospitalized in critical condition.

Two retired law enforcement officers died after collapsing on the route. Det. Raul Reyna, 53, suffered a heart attack at mile 24 near Olympic Boulevard and Westmoreland Avenue, two miles short of the finish line. He died at Good Samaritan Hospital. The 28-year Los Angeles Police Department veteran had worked on the use of force investigation team at Parker Center, officials said.

Retired Los Angeles County Sheriff's Deputy James Leone, 60, collapsed at mile 3, near Exposition Boulevard and Figueroa Street. "He just dropped … keeled over and hit his face on the pavement," said David Lawson, who interrupted his own run to administer CPR to the fallen runner."

His face was covered with blood and his eyes were open, but we never really got a pulse," said Lawson, a private pilot who volunteers part time on a ski patrol team. He and another runner, a physician, spent several minutes trying to revive Leone before paramedics arrived, said Lawson, who then resumed his run. Leone was pronounced dead upon arrival at California Hospital Medical Center.
