LATR Backyard Ultra

The LATR Backyard Ultra is a endurance event held at Lake Ahquabi State Park in Indianola, Iowa. The competition follows the backyard ultra format, where participants must complete a 4.167 mile lap every hour. To remain in the race, runners must be in the starting corral when the next hour begins. The race continues indefinitely until only one runner is able to complete a lap alone.

The course follows the Lake Trail in a counter-clockwise direction around Lake Ahquabi. The terrain consists primarily of dirt and gravel, featuring common trail elements such as roots, rocks, and uneven surfaces. The route is largely shaded by mature timber and offers views of the lake. During overnight hours, participants are required to use headlamps, though some additional lighting is placed along the trail.

Water, Tailwind, and snacks are available at the starting corral and at an aid station located near the mid-way point of the loop. Several restrooms are situated along the course and at the beach shelter house. Participants may receive assistance from their crew only between laps at the designated crew area near the beach shelter.

Specific regulations for the event include:

  • No trekking poles or personal aids are allowed on the course.
  • No pacers are permitted at any time.
  • Participants may not leave the course during a lap except to use restrooms.
  • The winner must complete one more lap than any other participant.

The event is a bronze-level affiliate of Big's Backyard Ultra. The winner receives a prize package and a bronze coin, which provides entry into a future silver bracket event. Visit the organization's website for the most recent information.
