The race at a glance

Route and elevation

The YMCA Famous Idaho Potato Marathon confirms May 15, 2027 at 07:00. The 50th-anniversary race uses the Boise Greenbelt and starts and finishes near the Morrison Center on Boise State University’s campus.

  • Full-marathon start: 07:00; the half starts at 09:00.
  • Friday collection: May 14, 15:00–19:00 at the Morrison Center.
  • Full and half marathon parking is assigned to the Brady garage.

Race guide

The 50th edition starts at the Morrison Center

The start is on the southeast side of the Morrison Center near South Brady Street, while the finish is on the northwest side near South Earle Street. Save those locations before arriving; “Morrison Center” alone does not identify the correct side for each stage of the morning.

The organizer provides a coloured parking pass at collection, with a digital version for runners unable to collect on Friday. Follow the marathon garage assignment rather than the shorter races’ parking instructions. The FAQ allows race-morning collection, but leave enough time for parking, the check-in queue and reaching the 07:00 start.

The event has four courses, with later races joining the day. Follow full-marathon signs at every split instead of following the runners ahead. Use the current marathon map from the organizer’s course page, and ask a marshal if the route is unclear. A familiar Greenbelt path is not necessarily the correct race route at every junction.

The FAQ lists aid approximately every one-and-a-half miles, with named nutrition suppliers, and says there is no fixed cutoff. Confirm final support arrangements if expecting a long day; an open-ended finish policy is not a guarantee of every service at every hour. Rehearse what you plan to consume and carry your preferred permitted products when the station assortment may differ. The 5K timetable conflicts across pages, so accompanying runners should verify their own start separately.
