The New York City Marathon always brings out the stars of the running world. This year, one of them is someone who's never competed in any big-time races.
Chilean miner Edison Pena is among the 45,000 people entered in the event on Sunday.
The 34-year-old is one of 33 miners rescued last month after spending 69 days trapped 2,300 feet (700 meters) underground by a cave-in.
An avid runner, he jogged several miles (kilometers) every day through tunnels, wearing steel-toed boots he cut down to the ankle.
NYC Marathon officials heard about Pena's subterranean training and planned to invite him as an honored guest. But he wanted to actually run the race.
Pena hopes to finish the 26.2 miles (42.2 kilometers) in 6 hours.
