FAQ
What are the most popular Idaho half marathons?
The Coeur d’Alene Half Marathon is one of Idaho’s most popular half marathons with just over 2,000 finishers.
What are the best Idaho half marathons for beginners in 2026?
We recommend the Coeur d’Alene Half Marathon, the Bear Lake Half Marathon, and the Mesa Falls Half Marathon.
We like the Coeur d’Alene for its crowds and flat, lakeside course.
We like the Bear Lake Half Marathon in St. Charles as the course actually crosses into three different states: Idaho, Wyoming, and Utah. An amazing race particularly if you’re trying to cross off racing in all 50 states.
The Mesa Falls Half Marathon in Ashton frequently comes up as one of the most scenic with a course along the Warm River.
