Questions about races in Boise

Does the calendar cover only the city of Boise?: It includes races in and around Boise, within 60 km. Each event page names the starting town; check it before planning your trip. Counts reflect the listed races, rather than every race that may exist.
Where can I check registration?: Open the event page and follow the organizer or registration link when available. Check places, price, start time and rules there; a calendar listing does not mean entries are still available.
How do the distance filters work?: 5K and 10K show distances close to 5 and 10 km; half and marathon show distances close to 21.1 and 42.2 km. Trail groups mountain races. Races without a published distance appear under All.
