Harvest Moon Backyard Ultra

Harvest Moon Backyard Ultra takes place on October 2, 2027 in Waterloo, IA at 3659 Wyth Rd. The event is limited to 100 runners; when spots are full a waitlist will be created. The race follows the Backyard Ultra format with results recorded in terms of completed yards.

Each lap is called a yard and is 4.167 miles. Runners must be inside the corral at the start of each hour and must start at the bell. A yard must be completed in less than one hour to count. Warnings are given 3, 2, and 1 minutes before the start of each yard. Restroom breaks are allowed but runners may not leave the course until the yard is complete. Non competitors may not accompany active runners on the course. No personal aid is allowed during a yard and no artificial aids including trekking poles are permitted.

Packet pickup is scheduled Friday, October 1 from 3:00 to 5:00 PM at a location to be determined, and at the Lodge on race day from 5:45 to 6:30 AM. Between yards crews may set up a single 10 by 10 tent near the start finish area; vehicles may be used instead. There is no overnight camping on Friday night and park gates open on race day morning. Final results report yards completed. Carrot milestones are awarded for 6, 12, 18, and 24 hours. The winner is the last person to complete an additional yard over all other finishers.
