Flag City Backyard Ultra

The Flag City Backyard Ultra takes place at Findlay Reservoir (East Side) near Findlay, Ohio. It is a last person standing format in which competitors must complete a 4.3 mile loop each hour. Loops start at the top of the hour and the event continues until one runner completes a loop alone; that runner is the winner and all others are recorded as DNF. If no runner can complete one more loop than everyone else, there is no winner.

The course is a simple, single loop around the reservoir with no elevation gain, no mud, and no roots. The route is described as having no shortcuts and being straightforward to follow.

The race is self supported. No food, drink, or supplies are provided on course, so runners must carry their own provisions and be prepared for changing conditions. Competitors are allowed to leave the course only for restrooms during a loop. No personal aid is allowed during a loop except common aid stations. Artificial aids, including trekking poles, are not permitted. Slower runners must allow passes. A whistle is used before each loop to signal the start.

All runners receive a technical shirt. Registration is $45 and increases to $55 on April 1; registration closes on September 3. Professional timing and live coverage will include ankle and bib tags, online live results, and a full event stream. Parking is available on the grass at the base of the reservoir; vehicles may drive to the top for drop off but may not remain there. Camping is permitted the night before with porta johns available and no running water. After expenses, remaining funds will be donated to Habitat for Humanity. All entry fees are non refundable and non transferable. Visit the organization's website for the most recent information.
