DETROIT, Michigan — Three men died within 16 minutes of each other while running a marathon in Detroit, officials said.
Temperatures were cool and emergency personnel stationed throughout the course were able to reach all three men seconds after they collapsed on Sunday morning, race officials said.
The first man to collapse was Daniel Langdon, 36, who fell at about 9:02 am (1302 GMT) between the 11- and 12-mile markers.
Rick Brown, 65, collapsed in the same area at 9:17 am (1317 GMT). A minute later, Jon Fenlon, 26, collapsed just after finishing the half-marathon in 1:53:37.
It was not clear whether Langdon and Brown were competing in the full or half marathon.
Deaths at marathons are relatively rare, with various studies placing the risk at between one in 75,000 and one in 126,000 participants.
More than 19,000 people participated in the marathon sponsored by the Detroit Free Press and Flagstar bank.
"On a day when so many people bring such energy and challenge themselves to do their utmost, this news is very difficult to hear," Free Press editor and publisher Paul Anger said.
"Our deepest sympathies are with the families."
This is just too sad and macabre.
