LA Marathon disqualifies 70-year-old for cheating.

LOS ANGELES — The Los Angeles Marathon disqualified 70-year-old runner Frank Meza, saying video shows he left the course during his record-setting performance in March and that his time during one stretch was so fast it was “impossible,” according to a report Monday.

Meza has repeatedly denied cheating and did so again on Monday, the Los Angeles Times reported.

“I didn’t cut the course,” he said.

Some in the running community have questioned his finish in 2 hours 53 minutes 10 seconds — the fastest ever for a man his age.
