The runners were among some 12,000 participants in the race,
one in a series of half and full Rock'n'Roll marathons held
across the United States and abroad but for the first time in
Raleigh, said Dan Cruz, spokesman for the marathon series.
Details on the deaths were still being gathered, but one runner
apparently collapsed near the finish line and the other further
back on the 13.1-mile (21-km) course, Cruz said.
The race continued, he said.
At least one of the runners who died was a man but no other
information was available, Cruz said.
Sunday was warm in Raleigh, with temperatures climbing into the
high 70s (mid 20 C) by early afternoon, according to the
National Weather Service.
"This is a tragic end to a successful week," Cruz said. "It's
sad for all parties involved."
The deaths were confirmed in a statement by marathon medical
director P.Z. Pearce. He did not cite the causes of death.
"We are greatly saddened by these tragic losses and our prayers
go out to the each of the runner's family and friends," Pearce
said. "We have spoken with each of the families and they have
asked everyone to kindly respect their privacy during this most
difficult of times."
