Saturday's Ironman 70.3 triathlon will cause some traffic delays as competitors run, bike and swim their way across the Treasure Valley.
The Idaho Department of Transportation cautioned motorists to keep an eye out for the more than 1,500 athletes who will be participating in the Boise event and allow more time for regular commutes. Police and volunteers will direct traffic along the race routes this weekend. Detours and road closures will be in place, ITD officials said.
Most of the running and biking routes will be in south, southeast and downtown Boise.
Boise residents who live alongside the race routes may need assistance accessing or leaving their homes, and may find themselves driving next to groups of cyclists. ITD urged drivers to keep the racers' safety in mind and drive carefully.
Athletes will start the triathlon with a swim in Lucky Peak's Barclay Bay, followed by biking 56 miles through Boise and Kuna, and finish with a 13.1 mile run along the Greenbelt to the 8th Street finish line.
Some roads may be impacted for several days, ITD officials said.
