Scorching heat on its way to Inland Northwest

At what point does an Ironman melt?

This weekend could reveal the answer. Record heat is expected to roast the region as tens of thousands of people head outside for two of the biggest community events of the year.

The National Weather Service forecast calls for triple-digit highs, including 104 on Sunday – the final day of Hoopfest in Spokane and the day about 2,000 triathletes hit the Ironman course in Coeur d’Alene.

Event organizers are bracing for health problems such as dehydration, cramps, sunburn, heat exhaustion, heat stroke and hyponatremia, or low sodium in the blood.

It’s shaping up to be the hottest Ironman in 13 years of the race in Coeur d’Alene, and competitors are being cautioned to take extra care to stay cool, hydrated and healthy for the grueling 2.4-mile swim in Lake Coeur d’Alene, 112-mile bike course and 26.2-mile run.

“Clearly, this is not a day for anyone to go for a personal best. You really just need to stay well within yourself and monitor yourself during the race for signs you are overheating,” said Dr. P.Z. Pearce, founder of Champions Sports Medicine in Spokane and medical director for the first two years of Ironman Coeur d’Alene.

“The problem with Ironman is you can’t get out of the sun,” Pearce said. “Sweating is the only method to cool when the ambient air temperature is above 92 degrees. … You’re going to have to replace your fluid loss from sweat but also replace the salt that you’re losing in sweat.”

When the level of sodium in the blood is too low, it can cause hyponatremia, a potentially fatal metabolic condition. “It’s one of the most serious things we see at Ironman,” Pearce said.

Athletes also must protect against sunburn but use sunscreen that allows them to sweat. “The waterproof ones plug up the pores and you don’t sweat as well,” he said.

Athletes should go a bit slower and take in more electrolytes and water throughout the race, said Keats McGonigal, operations manager for Ironman.

“Most of our athletes are pretty hardy by nature, and they’ve been training for this for months and years,” McGonigal said. “I’d say, in general, most of them are still going to be ready to go and make this thing happen.”

The Hoopfest 3-on-3 basketball tournament ordered cool-air misters and fans for this weekend, and organizers plan to have extra water for court monitors, who usually spend six to seven hours on the asphalt courts.

“It’s not the first time we’ve had hot weather, but it’s definitely the upper boundary,” Executive Director Matt Santangelo said. “Our biggest concern is for the court monitors, so we’re trying to be proactive and increase the number of water runs we are providing.”

Volunteer medical teams staffing Hoopfest will be prepared to treat heat stroke, heat exhaustion and burns, said Robbie Thorn, the emergency department manager at Providence Holy Family Hospital.

“When patients fall to the ground and are injured, they sometimes forget how hot the pavement is,” Thorn said. “If their skin is in contact with the asphalt too long, it can burn and require first aid.”

Crews will have extra IV supplies plus ice and towels to cool down patients, she said.

“Players can start hydrating early,” Thorn advised. “Drink lots of fluid the night before and continue throughout the day. Water and drinks with electrolytes are helpful for staying hydrated. Avoid carbonated beverages.”

McGonigal said Ironman will have more water, ice and Gatorade on the course this year, and the medical and changing tents will have fans or air conditioners. Misting stations and cold sponges will be provided on the marathon course, where competitors will experience the hottest part of the day.

“We’re also hitting hard with athlete education, trying to communicate to them it’s going to be warm and that they need to plan their nutrition and their hydration and pacing accordingly in order to have the most successful day they can,” he said.

Usually, the cold lake temperature is one of the chief environmental concerns of Ironman Coeur d’Alene, but lately the water has been above 70 degrees. Many swimmers likely will forgo wetsuits this year, McGonigal said.

The marathon will be especially taxing. “Probably most of our patients will be during that run course,” said Tom Greif, deputy chief of operations for the Coeur d’Alene Fire Department, which provides emergency medical services along the Ironman course.

“You’re looking at athletes being out there for 12-plus hours, some of them as much as 16,” Greif said. “We expect to see a lot of athletes not being able to adapt” to the heat.

Racers should not hesitate to stop to rest and cool off, or even quit if they feel they are overheating, Pearce said. The inaugural Coeur d’Alene Ironman in 2003 saw a high of 100 degrees, and more than a quarter of the athletes did not finish that year.

“You have until midnight to finish,” Pearce said. “Know you’re not going to have the best time you ever had.”
