marathoner and two other runners died during the Detroit Marathon Sunday, organizers said. Daniel Langdon, 36, of Laingsburg, collapsed at about 9:02 A.M. between the 11- and 12-mile (around 17-19-km) markers, said Rich Harshbarger, vice president of consumer marketing for the Detroit Media Partnership. Rick Brown, 65, of Marietta, Ohio, collapsed at 9:17 A.M., near where Langdon went down, and 26-year-old Jon Fenlon of Waterford collapsed at about 9:18 A.M., just after finishing the half-marathon in 1:53:37, Harshbarger said. It was unclear whether Brown and Langdon were participating in the 13.1-mile (21-km) half marathon or the full race. Harshbarger told the Free Press that there were at least six medical stations on the race course and that emergency personnel were on the scene within seconds. The temperature was about 28 degrees (-2.22 Celsius) when the marathon started and had risen to 41 degrees (5 Celsius) by 10 A.M. More than 19,000 people took part in the race. Nicholas Stanko, of Haslett, Michigan, took first place in the marathon with a time of 2:20:24. Sarah Plaxton, of Highland, Michigan, was the top female finisher in the marathon with a time of 2:57:09.
