The Ironman 70.3 has been coming to Boise for the past seven years — but this year is different. The morning start time. No professional class, leaving the day to amateurs and age-groupers. A tweaked course to alleviate the race’s impact on traffic. And it could be the final year the triathlon returns as the Boise Convention & Visitors Bureau and the World Triathlon Corp. continue to negotiate a contract for future years. But one thing remains the same: The challenge presented to the triathletes, who will tackle a 1.2-mile swim at Lucky Peak, a 56-mile bike ride from Lucky Peak to South Boise, and a 13.1-mile run on the Greenbelt with a finish in Julia Davis Park. Athletes should start hitting the finish line in 4-plus hours.
