Common Questions About Racing in Boise
When is race season in Boise?
October is the busiest month for races in Boise, with 6 of the 23, followed by May with 4. If you are flexible on the date, that is the quickest way to narrow things down.
How early should I register for a race in Boise?
15 of the 23 races in Boise already have a price increase scheduled, so entry gets more expensive the longer you leave it. Race pricing almost always steps up as the date approaches, and signing up early is usually the cheapest option.
Are Boise races beginner-friendly?
Yes, for the most part. Across the 11 races in Boise with published results, the typical median finish is around 48:45, which means half of every one of those fields came in slower than that. Recreational runners and walk-runners are the bulk of these fields, not the exception.
Where can I train for a race in Boise?
Browse Boise run clubs on RunSesh to find a training group at your pace.
Are there trail races near Boise?
Yes, one race around Boise gets you off the pavement: 1 is a trail race. Surfaces are not always published, so it is worth checking a specific race before you register.
