From around the Northwest, the nation and the world, they’ve made their way to Coeur d’Alene this week for the 11th Ironman to start and finish at the city’s celebrated shoreline. More than 2,600 athletes will compete in Sunday’s triathlon, a 140-mile course that begins with a swim in Lake Coeur d’Alene, follows with a demanding bike ride on the west side of the lake and ends with a marathon on the north shore. They have a little more than 17 hours to finish.
