Just don't do it

Jogging in LA will kill you:

LOS ANGELES (Reuters) - Two men, both veteran law enforcement officers, suffered fatal heart attacks while running in Sunday's Los Angeles Marathon, marking the first deaths in the event since 1990, organizers said on Monday.

Reyna collapsed 3 miles into the race. He was taken to a hospital where he was pronounced dead. Leone was stricken less than 3 miles from the finish line and died at a local hospital, officials said.

A third man had a heart attack about seven blocks into the race but survived.
