Triple-digit temperatures and a swarm of angry bees did not deter 1,335 athletes from completing Ironman Coeur d'Alene 2015.

There were 1,711 hopefuls who started the triathlon Sunday morning, and by the 11 p.m. cutoff, 376 had dropped out. A total of 2,012 athletes registered for this year's Ironman Coeur d'Alene, significantly fewer than in previous years. In 2014, 2,466 athletes registered.

Ironman finishers must swim 2.4 miles, bicycle 112 miles and run another 26.2 miles. This year, they did most of it in 100-plus degree heat.

"The number of DNFs was higher than normal but was not the highest we have had at a race," Ironman spokesman Dan Berglund told The Press Monday. DNF is an acronym for "did not finish."

Pawel Kozlowksi, a triathlon enthusiast in New York, tweeted a different definition of DNF for this year's Ironman Coeur d'Alene: "DNF=Did Not Fry."

And there was some "frying" Sunday in the Lake City.

Coeur d'Alene Fire Chief Kenny Gabriel said emergency workers were slammed during the event.

"There was a rush around 1 p.m. when we were as busy as we could possibly be," he said, adding triage played a major role. "The sag wagons were really helpful."

Sag wagons are support vehicles that travel behind the racers and pick them up if they fall behind or drop out. Gabriel said they were transporting racers that needed minor medical attention, which freed up the ambulances and other emergency vehicles.

He said the drive times getting to calls were a little challenging, but overall "it was a Herculean effort for everyone involved in keeping the athletes safe."

Lisa Aitken, spokeswoman for Kootenai Health, said hospital staff members treated significantly more Ironman athletes and members of the general public for heat-related incidents than they did last year.

"Eight Ironman athletes came to Kootenai Health for heat-related illnesses and two were admitted to the hospital," Aitken told The Press. "Fortunately, a lot of preparation was done in anticipation of increased heat-related illness. We had plenty of extra staffing and supplies on hand so we were able to care for patients as we would any other day."

Local law enforcement agencies were not significantly affected by the day's events.

Kootenai County Sheriff's Lt. Stu Miller told The Press calls for service were "pretty average" for the weekend. The sheriff's dispatch center received 305 calls from midnight Saturday to midnight Sunday. The week before, during the same time frame, sheriff's deputies received 289 calls.

Ironman organizers have their own dispatch, Miller said, so event-related calls don't go to the sheriff's office.

Coeur d'Alene Police Sgt. Christie Wood said her department saw no major incidents, other than being called upon to assist Idaho State Police when a truck carrying bees overturned on Interstate 90.

Although there were no threats, Wood confirmed that extra law enforcement officers provided additional security during the event, since terrorist activities have occurred in recent years at large public events throughout the nation.
